• Complex event system for DungeonKeeper like game

  - by paul424

  I am working on opensource GPL3 game. http://opendungeons.sourceforge.net/ , new coders would be welcome. Now there's design question regarding Event System: We want to improve the game logic, that is program a new event system. I will just repost what's settled up already on http://forum.freegamedev.net/viewtopic.php?f=45&t=3033. From the discussion came the idea of the Publisher / Subscriber pattern + "domains": My current idea is to use the subscirbers / publishers model. Its similar to Observable pattern, but instead one subscribes to Events types, not Object's Events. For each Event would like to have both static and dynamic type. Static that is its's type would be resolved by belonging to the proper inherited class from Event. That is from Event we would have EventTile, EventCreature, EvenMapLoader, EventGameMap etc. From that there are of course subtypes like EventCreature would be EventKobold, EventKnight, EventTentacle etc. The listeners would collect the event from publishers, and send them subcribers , each of them would be a global singleton. The Listeners type hierachy would exactly mirror the type hierarchy of Events. In each constructor of Event type, the created instance would notify the proper listeners. That is when calling EventKnight the proper ctor would notify the Listeners : EventListener, CreatureLisener and KnightListener. The default action for an listner would be to notify all subscribers, but there would be some exceptions , like EventAttack would notify AttackListener which would dispatch event by the dynamic part ( that is the Creature pointer or hash). Any comments ? #include <vector> class Subscriber; class SubscriberAttack; class Event{ private: int foo; int bar; protected: // static std::vector<Publisher*> publishersList; static std::vector<Subscriber*> subscribersList; static std::vector<Event*> eventQueue; public: Event(){ eventQueue.push_back(this); } static int subscribe(Subscriber* ss); static int unsubscribe(Subscriber* ss); //static int reg_publisher(Publisher* pp); //static int unreg_publisher(Publisher* pp); }; // class Publisher{ // }; class Subscriber{ public: int (*newEvent) (Event* ee); Subscriber( ){ Event::subscribe(this); } Subscriber( int (*fp) (Event* ee) ):newEvent(fp){ Subscriber(); } ~Subscriber(){ Event::unsubscribe(this); } }; class EventAttack: Event{ private: int foo; int bar; protected: // static std::vector<Publisher*> publishersList; static std::vector<SubscriberAttack*> subscribersList; static std::vector<EventAttack*> eventQueue; public: EventAttack(){ eventQueue.push_back(this); } static int subscribe(SubscriberAttack* ss); static int unsubscribe(SubscriberAttack* ss); //static int reg_publisher(Publisher* pp); //static int unreg_publisher(Publisher* pp); }; class AttackSubscriber :Subscriber{ public: int (*newEvent) (EventAttack* ee); AttackSubscriber( ){ EventAttack::subscribe(this); } AttackSubscriber( int (*fp) (EventAttack* ee) ):newEventAttack(fp){ AttackSubscriber(); } ~AttackSubscriber(){ EventAttack::unsubscribe(this); } }; From that point, others wanted the Subject-Observer pattern, that is one would subscribe to all event types produced by particular object. That way it came out to add the domain system : Huh, to meet the ability to listen to particular game's object events, I though of introducing entity domains . Domains are trees, which nodes are labeled by unique names for each level. ( like the www addresses ). Each Entity wanting to participate in our event system ( that is be able to publish / produce events ) should at least now its domain name. That would end up in Player1/Room/Treasury/#24 or Player1/Creature/Kobold/#3 producing events. The subscriber picks some part of a tree. For example by specifiing subtree with the root in one of the nodes like Player1/Room/* ,would subscribe us to all Players1's room's event, and Player1/Creature/Kobold/#3 would subscribe to Players' third kobold's event. Does such event system make sense to you ? I have many implementation details to ask as well, but first let's start some general discussion. Note1: Notice that in the case of a fight between two creatues fight , the creature being attacked would have to throw an event, becuase it is HE/SHE/IT who have its domain address. So that would be BeingAttackedEvent() etc. I will edit that post if some other reflections on this would come out. Note2: the existing class hierarchy might be used to get the domains addresses being build in constructor . In a ctor you would just add + ."className" to domain address. If you are in a class'es hierarchy leaf constructor one might use nextID , hash or any other charactteristic, just to make the addresses distinguishable . Note3:subscribing to all entity's Events would require knowledge of all possible events produced by this entity . This could be done in one function call, but information on E produced would have to be handled for every Entity. SmartNote4 : Finding proper subscribers in a tree would be easy. One would start in particular Leaf for example Player1/Creature/Kobold/#3 and go up one parent a time , notifiying each Subscriber in a Node ie. : Player1/Creature/Kobold/* , Player1/Creature/* , Player1/* etc, , up to a root that is /* .<<<< Note5: The Event system was needed to have some way of incorporating Angelscript code into application. So the Event dispatcher was to be a gate to A-script functions. But it came out to this one.

• Part 3 of 4 : Tips/Tricks for Silverlight Developers.

  - by mbcrump

  Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #11) What is it? Underline Text in a TextBlock. Why do I care? I’ve seen people do some crazy things to get underlined text in a Silverlight Application. In case you didn’t know there is a property for that. How do I do it: On a TextBlock you have a property called TextDecorations. You can easily set this property in XAML or CodeBehind with the following snippet: <UserControl x:Class="SilverlightApplication19.MainPage" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <TextBlock Name="txtTB" Text="MichaelCrump.NET" TextDecorations="Underline" /> </Grid> </UserControl> or you can do it in CodeBehind… txtTB.TextDecorations = TextDecorations.Underline;   Tip/Trick #12) What is it? Get the browser information from a Silverlight Application. Why do I care? This will allow you to program around certain browser conditions that otherwise may not be aware of. How do I do it: It is very easy to extract Browser Information out a Silverlight Application by using the BrowserInformation class. You can copy/paste this code snippet to have access to all of them. string strBrowserName = HtmlPage.BrowserInformation.Name; string strBrowserMinorVersion = HtmlPage.BrowserInformation.BrowserVersion.Minor.ToString(); string strIsCookiesEnabled = HtmlPage.BrowserInformation.CookiesEnabled.ToString(); string strPlatform = HtmlPage.BrowserInformation.Platform; string strProductName = HtmlPage.BrowserInformation.ProductName; string strProductVersion = HtmlPage.BrowserInformation.ProductVersion; string strUserAgent = HtmlPage.BrowserInformation.UserAgent; string strBrowserVersion = HtmlPage.BrowserInformation.BrowserVersion.ToString(); string strBrowserMajorVersion = HtmlPage.BrowserInformation.BrowserVersion.Major.ToString(); Tip/Trick #13) What is it? Always check the minRuntimeVersion after creating a new Silverlight Application. Why do I care? Whenever you create a new Silverlight Application and host it inside of an ASP.net website you will notice Visual Studio generates some code for you as shown below. The minRuntimeVersion value is set by the SDK installed on your system. Be careful, if you are playing with beta’s like “Lightswitch” because you will have a higher version of the SDK installed. So when you create a new Silverlight 4 project and deploy it your customers they will get a prompt telling them they need to upgrade Silverlight. They also will not be able to upgrade to your version because its not released to the public yet. How do I do it: Open up the .aspx or .html file Visual Studio generated and look for the line below. Make sure it matches whatever version you are actually targeting. Tip/Trick #14) What is it? The VisualTreeHelper class provides useful methods for involving nodes in a visual tree. Why do I care? It’s nice to have the ability to “walk” a visual tree or to get the rendered elements of a ListBox. I have it very useful for debugging my Silverlight application. How do I do it: Many examples exist on the web, but say that you have a huge Silverlight application and want to find the parent object of a control.  In the code snippet below, we would get 3 MessageBoxes with (StackPanel first, Grid second and UserControl Third). This is a tiny application, but imagine how helpful this would be on a large project. <UserControl x:Class="SilverlightApplication18.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <StackPanel> <Button Content="Button" Height="23" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </StackPanel> </Grid> </UserControl> private void button1_Click(object sender, RoutedEventArgs e) { DependencyObject obj = button1; while ((obj = VisualTreeHelper.GetParent(obj)) != null) { MessageBox.Show(obj.GetType().ToString()); } } Tip/Trick #15) What is it? Add ChildWindows to your Silverlight Application. Why do I care? ChildWindows are a great way to direct a user attention to a particular part of your application. This could be used when saving or entering data. How do I do it: Right click your Silverlight Application and click Add then New Item. Select Silverlight Child Window as shown below. Add an event and call the ChildWindow with the following snippet below: private void button1_Click(object sender, RoutedEventArgs e) { ChildWindow1 cw = new ChildWindow1(); cw.Show(); } Your main application can still process information but this screen forces the user to select an action before proceeding. The code behind of the ChildWindow will look like the following: namespace SilverlightApplication18 { public partial class ChildWindow1 : ChildWindow { public ChildWindow1() { InitializeComponent(); } private void OKButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = true; //TODO: Add logic to save what the user entered. } private void CancelButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = false; } } } Thanks for reading and please come back for Part 4.  Subscribe to my feed CodeProject

• Compiling JS-Test-Driver Plugin and Installing it on Eclipse 3.5.1 Galileo?

  I downloaded the source of the js-test-driver from: http://js-test-driver.googlecode.com/svn/tags/1.2 It compiles just fine, but one of the unit tests fails: [junit] Tests run: 1, Failures: 1, Errors: 0, Time elapsed: 0.012 sec [junit] Test com.google.jstestdriver.eclipse.ui.views.FailureOnlyViewerFilterTest FAILED I am using: - ANT 1.7.1 - javac 1.6.0_12 And I'm trying to install the js-test-driver plugin on Eclipse 3.5.1 Galileo Despite the failed test I installed the plugin into my C:\eclipse\dropins\js-test-driver directory by copying (exporting from svn) the compiled feature and plugins directories there, to see if it would yield any hints to what the problem is. When I started eclipse, added the plugin to the panel using Window-Show View-Other...

• asp.net mvc jquery + tabs +jqgrid +jqgrid loaded only for first tab

  - by niao

  Greetings, I have a problem using jqgrid and jquery tab (I am coding in asp.net mvc) I have two tabs. Each tabs should contains jqgrid with different data. I specify tabs as follows: <script type="text/javascript"> $(document).ready(function() { $("#tabs").tabs(); getContentTab (1); }); function getContentTab(index) { var url='<%= Url.Content("~/Admin/GetWorkspaces") %>/' + index; var targetDiv = "#tabs-" + index; var ajaxLoading = "<img id='ajax-loader' src='<%= Url.Content("~/Content") %>/ajax-loader.gif' align='left' height='28' width='28'>"; $(targetDiv).html("<p>" + ajaxLoading + " Loading...</p>"); $.get(url,null, function(result) { $(targetDiv).html(result); }); } </script> <div id="tabs"> <ul> <li><a href="#tabs-1" onclick="getContentTab(1);">tab1</a></li> <li><a href="#tabs-2" onclick="getContentTab(2);">tab2</a></li> </ul> <div id="tabs-1"> </div> <div id="tabs-2"> </div> </div> As seen above GetWorkspaces action gets my tabs: public ActionResult GetWorkspaces(int id) { string viewName = string.Empty; switch (id) { case 1: viewName = "MarketplaceOfferView"; break; case 2: viewName = "MyMessagesView"; break; } return PartialView(viewName); } each of view is a partial view. In these partial views I have jqgrids specified as follows: <script type="text/javascript"> jQuery("#list").ready(function() { jQuery("#list").jqGrid({ url: '/Admin/GetGridData/', datatype: 'json', mtype: 'GET', colNames: ['Klient', 'Zapytanie', 'Atrakcyjnosc', 'Cena', 'Data poczatkowa', 'Data koncowa', 'Branza', 'Lokalizacja' ], colModel: [ { name: 'CompanyName', index: 'CompanyName', width: 150, align: 'left' }, { name: 'Content', index: 'ContactName', width: 300, align: 'left' }, { name: 'Rating', index: 'Address', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'PostalCode', width: 100, align: 'left' } ], pager: jQuery('#pager'), rowNum: 100, rowList: [5, 10, 20, 50], sortname: 'Operator.FullName', sortorder: "asc", viewrecords: true, imgpath: '/scripts/themes/steel/images', caption: 'Historia moich wiadomosci', height:400 }); // .navGrid(pager, { edit: true, add: false, del: false, refresh: true, search: false }); }); </script> Historia moich wiadomosci <table id="list" class="scroll" cellpadding="0" cellspacing="0" width="100%"> </table> <div id="pager" class="scroll" style="text-align: center;"> </div> For second view I have an action: /Admin/GetGridDataForTab2/ THe problem is that I see a jqgrid only when I click on first tab. When I click on second tab the grid is not displayed and /Admin/GetGridData/ is not executed. Does anybody have an idea what is wrong?

  I have a ContextMenu with the ItemsSource bound to the selected item of a list view, like this: <ContextMenu ItemsSource="{Binding Path=PlacementTarget.SelectedItem, RelativeSource={RelativeSource Self}, Converter={StaticResource possibleConverter}}"/> The possibleConverter enumerates all possible values for a property of the the selected item, which are shown in the context menu. In the Opened event of the context menu, I select the current value like this: var cm = e.OriginalSource as ContextMenu; if (cm != null) { var lv = cm.PlacementTarget as ListView; var field = lv.SelectedItem as Field; var item = cm.ItemContainerGenerator.ContainerFromItem(cm.Items.OfType<object>().Where(o => o.ToString().Equals(field.StringValue)).FirstOrDefault()) as MenuItem; if (item != null) { item.IsChecked = true; } } Not particularly elegant, but it works. With the debugger I verified that the ContextMenu.Items.Count property has a non-zero value when expected (i.e. cm.Items.Count is non-zero in the if). So far, so good. There are, however, items in the listview where the context menu will have no items. In this case, an empty menu is shown. I tried to suppress this in the ContextMenuOpening event in the list view, like this: var lv = sender as ListView; if (lv != null) { var cm = lv.ContextMenu; if ((cm != null) && (cm.Items.Count > 0)) { // Here we want to check the current item, which is currently done in the Opened event. } else { e.Handled = true; } } Seems like it should work. However, cm.Items.Count is always zero. This is true even if ListView.SelectedItem did not change: For an item with menu entries, the menu is shown correctly after the first click, so the data binding has already happend. It is shown correct the second time as well, but in any case, Items.Count is zero in the ContextMenuOpening event. What am I missing? How can I suppress empty context menus? Why is the count zero in the ContextMenuOpening handler, which is in Windows Forms (ContextMenuStrip.Opening) the canonical point where to do these things? EDIT: Upon further investigating, it turns out that in the ContextMenuOpening handler, any binding to the listview fails, which is why ItemsSource is null. I tried to bind via ElementName, via a FindAncestor relationship, all to no avail. The PlacementTarget is null during that event. An ugly hack worked though: In the ContextMenuOpening event, I assign the list view to the ContextMenu.Tag property, while the ItemsSource binding now binds to Tag.SelectedItem. This updates the binding, so Items.Count is what it should be. It's still strange. How can you do meaningful things in ContextMenuOpening other than replacing the menu or something, if the binding fails because somehow the context menu is out of context during the event? Was it only tested with static pre-defined menu items?

• Own DataFormWebPart: Unable to display this Web Part.

  - by user307852

  Hi, What I want is to display a paginable list from my custom data source. All came from the fact that I needed some logical relationships between seach scopes and some dates. I considered ContentQueryWebpart, but CAML is too complicated as I have plenty of different conditions, CoreResults webpart is too limited as it uses KeyWordQuery so I inherited from DataFormWebPart to display my own custom search results from my own custom xml source. Thats the best way i am aware of... I knew I needed some configuration to write in my pageLayout like MyWebParts:MyCustomWebPart etc so I went to Designer, put DataFormWebPart on a page, linked it to list of pages, and set multiple item view and that gave me some configuration.. Firstly i checked if DataFormWebPart works when put on pageLayout and it sucessfully displayed my pages list in pages library. But that was not what I wanted, i needed to set my own XML data source... I then changed the configuration of WebPartPages:DataFormWebPart to match mine and detach from any listName or listId and I change the XSL tag to much simplier to display all results and now I am getting: Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator. and there is no way to know what is wrong:/ The webpart public class MyCustomWebPart : DataFormWebPart{ public override void DataBind() { ...... XmlDataSource source = new XmlDataSource(); source.Data = doc.InnerXml; this.DataSource=source; base.DataBind(); } } The doc XML: <dsQueryResponse><Rows><Row URL="http://myserver/sites/sc/myDoc.doc" TITLE="Specification.doc" AUTHOR="System.String[]" /></Rows></dsQueryResponse> The webpart is in PageLayout, inserted without webpartzone: <MyWebParts:MyCustomWebPart runat="server" Description="" ListDisplayName="" PartOrder="2" HelpLink="" AllowRemove="True" IsVisible="True" AllowHide="True" UseSQLDataSourcePaging="True" ExportControlledProperties="True" DataSourceID="" Title="" ViewFlag="0" NoDefaultStyle="TRUE" AllowConnect="True" FrameState="Normal" PageSize="10" PartImageLarge="" AsyncRefresh="True" ExportMode="All" Dir="Default" DetailLink="" ShowWithSampleData="False" FrameType="None" PartImageSmall="" IsIncluded="True" SuppressWebPartChrome="False" AllowEdit="True" ManualRefresh="False" ChromeType="None" AutoRefresh="False" AutoRefreshInterval="60" AllowMinimize="True" ViewContentTypeId="" InitialAsyncDataFetch="False" MissingAssembly="Cannot import this Web Part."

• ASP.NET MVC2 Model Validation Fails with Non-US Date Format

  - by 81bronco

  I have a small MVC2 app that displays in two cultures: en-US and es-MX. One portion contains a user input for a date that is pre-populated with the current date in the Model. When using en-US, the date field is displayed as MM/dd/yyyy and can be changed using the same format without causing any validation errors. When using es-MX, the date field is displayed as dd/MM/yyyy, but when the date is edited in this format, the server-side validation fails with the message: The value '17/05/1991' is not valid for The Date. One of the first things that jumps out at me about that message is that it is not localized. Both the message itself (which I do not think I can control) and the Display Name of the field (which I can control and is localized in my code). Should be displaying in a localized format. I have tried stepping through the code to see exactly where the validation is failing, but it seems to be happening inside some of the compiled MVC or DataAnnotations code that I cannot see. Application details: IIS6, ASP.NET 3.5 (C#), MVC 2 RTM Sample Model Code: public class TestVieModel{ [LocalizedDisplayNameDisplayName("TheDateDisplayName", NameResourceType=typeof(Resources.Model.TestViewModel))] [Required(ErrorMessageResourceName="TheDateValidationMessageRequired", ErrorMessageResourceType=typeof(Resources.Model.TestViewModel))] [DataType(DataType.Date)] public DateTime TheDate { get; set; } } Sample Controller Action Code: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Save(TestViewModel model) { if(ModelState.IsValid) { // <--- Always is false when using es-MX and a date foramtted as dd/MM/yyyy. // Do other stuff return this.View("Complete", model); } // Validation failed, redisplay the form. return this.View("Enter", model); } Sample View Code: <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<HispanicSweeps.Web.Model.LosMets.EnterViewModel>" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Test</title> </head> <body> <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.DateOfBirth) %> </div> <div class="editor-field"> <%= Html.EditorFor(model => model.DateOfBirth) %> <%= Html.ValidationMessageFor(model => model.DateOfBirth) %> </div> <p><input type="submit" value="Save" /></p> </fieldset> <% } %> </body> </html>

• Best practices for using the Entity Framework with WPF DataBinding

  - by Ken Smith

  I'm in the process of building my first real WPF application (i.e., the first intended to be used by someone besides me), and I'm still wrapping my head around the best way to do things in WPF. It's a fairly simple data access application using the still-fairly-new Entity Framework, but I haven't been able to find a lot of guidance online for the best way to use these two technologies (WPF and EF) together. So I thought I'd toss out how I'm approaching it, and see if anyone has any better suggestions. I'm using the Entity Framework with SQL Server 2008. The EF strikes me as both much more complicated than it needs to be, and not yet mature, but Linq-to-SQL is apparently dead, so I might as well use the technology that MS seems to be focusing on. This is a simple application, so I haven't (yet) seen fit to build a separate data layer around it. When I want to get at data, I use fairly simple Linq-to-Entity queries, usually straight from my code-behind, e.g.: var families = from family in entities.Family.Include("Person") orderby family.PrimaryLastName, family.Tag select family; Linq-to-Entity queries return an IOrderedQueryable result, which doesn't automatically reflect changes in the underlying data, e.g., if I add a new record via code to the entity data model, the existence of this new record is not automatically reflected in the various controls referencing the Linq query. Consequently, I'm throwing the results of these queries into an ObservableCollection, to capture underlying data changes: familyOC = new ObservableCollection<Family>(families.ToList()); I then map the ObservableCollection to a CollectionViewSource, so that I can get filtering, sorting, etc., without having to return to the database. familyCVS.Source = familyOC; familyCVS.View.Filter = new Predicate<object>(ApplyFamilyFilter); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("PrimaryLastName", System.ComponentModel.ListSortDirection.Ascending)); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("Tag", System.ComponentModel.ListSortDirection.Ascending)); I then bind the various controls and what-not to that CollectionViewSource: <ListBox DockPanel.Dock="Bottom" Margin="5,5,5,5" Name="familyList" ItemsSource="{Binding Source={StaticResource familyCVS}, Path=., Mode=TwoWay}" IsSynchronizedWithCurrentItem="True" ItemTemplate="{StaticResource familyTemplate}" SelectionChanged="familyList_SelectionChanged" /> When I need to add or delete records/objects, I manually do so from both the entity data model, and the ObservableCollection: private void DeletePerson(Person person) { entities.DeleteObject(person); entities.SaveChanges(); personOC.Remove(person); } I'm generally using StackPanel and DockPanel controls to position elements. Sometimes I'll use a Grid, but it seems hard to maintain: if you want to add a new row to the top of your grid, you have to touch every control directly hosted by the grid to tell it to use a new line. Uggh. (Microsoft has never really seemed to get the DRY concept.) I almost never use the VS WPF designer to add, modify or position controls. The WPF designer that comes with VS is sort of vaguely helpful to see what your form is going to look like, but even then, well, not really, especially if you're using data templates that aren't binding to data that's available at design time. If I need to edit my XAML, I take it like a man and do it manually. Most of my real code is in C# rather than XAML. As I've mentioned elsewhere, entirely aside from the fact that I'm not yet used to "thinking" in it, XAML strikes me as a clunky, ugly language, that also happens to come with poor designer and intellisense support, and that can't be debugged. Uggh. Consequently, whenever I can see clearly how to do something in C# code-behind that I can't easily see how to do in XAML, I do it in C#, with no apologies. There's been plenty written about how it's a good practice to almost never use code-behind in WPF page (say, for event-handling), but so far at least, that makes no sense to me whatsoever. Why should I do something in an ugly, clunky language with god-awful syntax, an astonishingly bad editor, and virtually no type safety, when I can use a nice, clean language like C# that has a world-class editor, near-perfect intellisense, and unparalleled type safety? So that's where I'm at. Any suggestions? Am I missing any big parts of this? Anything that I should really think about doing differently?

• Filtering in a HierarchicalDataTemplate via MarkupExtension?

  - by Dan Bryant

  I'm trying to create a MarkupExtension to allow filtering of items in an ItemsSource of a HierarchicalDataTemplate. In particular, I'd like to be able to supply a method name that will be executed on the DataContext in order to perform the filtering. The usage syntax I'm after looks like this: <HierarchicalDataTemplate DataType="{x:Type src:DeviceBindingViewModel}" ItemsSource="{Utilities:FilterCollection {Binding Definition.Entries}, MethodName=FilterEntries}"> <StackPanel Orientation="Horizontal"> <Image Source="{StaticResource BindingImage}" Width="24" Height="24" Margin="3"/> <TextBlock Text="{Binding DisplayName}" FontSize="12" VerticalAlignment="Center"/> </StackPanel> </HierarchicalDataTemplate> My code for the custom MarkupExtension looks like this: public sealed class FilterCollectionExtension : MarkupExtension { private readonly MultiBinding _binding; private Predicate<Object> _filterMethod; public string MethodName { get; set; } public FilterCollectionExtension(Binding binding) { _binding = new MultiBinding(); _binding.Bindings.Add(binding); //We package a reference to the DataContext with the binding so that the Converter has access to it var selfBinding = new Binding {RelativeSource = RelativeSource.Self}; _binding.Bindings.Add(selfBinding); _binding.Converter = new InternalConverter(this); } public FilterCollectionExtension(Binding binding, string methodName) : this(binding) { MethodName = methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { return _binding; } private bool FilterInternal(Object dataContext, Object value) { //Filtering is only applicable if a DataContext is defined if (dataContext != null) { if (_filterMethod == null) { var type = dataContext.GetType(); var method = type.GetMethod(MethodName, new[] { typeof(Object) }); if (method == null || method.ReturnType != typeof(bool)) throw new InvalidOperationException("Could not locate a filter predicate named " + MethodName + " on the DataContext"); _filterMethod = (Predicate<Object>)Delegate.CreateDelegate(typeof(Predicate<Object>), dataContext, method); } else { if (_filterMethod.Target != dataContext) { _filterMethod = (Predicate<Object>) Delegate.CreateDelegate(typeof (Predicate<Object>), dataContext, _filterMethod.Method); } } if (_filterMethod != null) return _filterMethod(value); } //If no filtering resolved, just allow all elements return true; } private class InternalConverter : IMultiValueConverter { private readonly FilterCollectionExtension _owner; public InternalConverter(FilterCollectionExtension owner) { _owner = owner; } public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { var enumerable = values[0]; var targetElement = (FrameworkElement)values[1]; var view = CollectionViewSource.GetDefaultView(enumerable); view.Filter = item => _owner.FilterInternal(targetElement.DataContext, item); return view; } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) { throw new NotSupportedException("Cannot convert back"); } } } I can see that the extension is instantiated and I can see it return the MultiBinding that is used by the Template. I also see the call to the InternalConverter.Convert method, which sees the expected parameters (I see the collection provided by the nested {Binding}) and is successfully able to retrieve the ICollectionView for the incoming collection. The only problem is that FilterInternal never gets called. The template is ultimately being used by a TreeView, if that's relevant. I haven't been able to figure out why the FilterInternal method is not being called and I was hoping somebody might be able to offer some insight.

• Problems with Android Fragment back stack

  - by DexterMoon

  I've got a massive problem with the way the android fragment backstack seems to work and would be most grateful for any help that is offered. Imagine you have 3 Fragments [1] [2] [3] I want the user to be able to navigate [1] > [2] > [3] but on the way back (pressing back button) [3] > [1]. As I would have imagined this would be accomplished by not calling addToBackStack(..) when creating the transaction that brings fragment [2] into the fragment holder defined in XML. The reality of this seems as though that if I dont want [2] to appear again when user presses back button on [3], I must not call addToBackStack in the transaction that shows fragment [3]. This seems completely counter-intuitive (perhaps coming from the iOS world). Anyway if i do it this way, when I go from [1] > [2] and press back I arrive back at [1] as expected. If I go [1] > [2] > [3] and then press back I jump back to [1] (as expected). Now the strange behavior happens when I try and jump to [2] again from [1]. First of all [3] is briefly displayed before [2] comes into view. If I press back at this point [3] is displayed, and if I press back once again the app exits. Can anyone help me to understand whats going on here? And here is the layout xml file for my main activity: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <fragment android:id="@+id/headerFragment" android:layout_width="match_parent" android:layout_height="wrap_content" class="com.fragment_test.FragmentControls" > <!-- Preview: layout=@layout/details --> </fragment> <FrameLayout android:id="@+id/detailFragment" android:layout_width="match_parent" android:layout_height="fill_parent" /> Update This is the code I'm using to build by nav heirarchy Fragment frag; FragmentTransaction transaction; //Create The first fragment [1], add it to the view, BUT Dont add the transaction to the backstack frag = new Fragment1(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.commit(); //Create the second [2] fragment, add it to the view and add the transaction that replaces the first fragment to the backstack frag = new Fragment2(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.addToBackStack(null); transaction.commit(); //Create third fragment frag = new Fragment3(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.commit(); //END OF SETUP CODE------------------------- //NOW: //Press back once and then issue the following code: frag = new Fragment2(); transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.detailFragment, frag); transaction.addToBackStack(null); transaction.commit(); //Now press back again and you end up at fragment [3] not [1] Many thanks

• ASP.NET MVC 2 - Saving child entities on form submit

  - by Justin

  Hey, I'm using ASP.NET MVC 2 and am struggling with saving child entities. I have an existing Invoice entity (which I create on a separate form) and then I have a LogHours view that I'd like to use to save InvoiceLog's, which are child entities of Invoice. Here's the view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TothSolutions.Data.Invoice>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Log Hours </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> $(document).ready(function () { $("#InvoiceLogs_0__Description").focus(); }); </script> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Log Hours</h2> <% using (Html.BeginForm("SaveHours", "Invoices")) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <table> <tr> <th>Date</th> <th>Description</th> <th>Hours</th> </tr> <% int index = 0; foreach (var log in Model.InvoiceLogs) { %> <tr> <td><%: log.LogDate.ToShortDateString() %></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Description")%></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Hours")%></td> <td>Hours</td> </tr> <% index++; } %> </table> <p> <%: Html.Hidden("InvoiceID") %> <%: Html.Hidden("CreateDate") %> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%: Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> And here's the controller code: //GET: /Secure/Invoices/LogHours/ public ActionResult LogHours(int id) { var invoice = DataContext.InvoiceData.Get(id); if (invoice == null) { throw new Exception("Invoice not found with id: " + id); } return View(invoice); } //POST: /Secure/Invoices/SaveHours/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveHours([Bind(Exclude = "InvoiceLogs")]Invoice invoice) { TryUpdateModel(invoice.InvoiceLogs, "InvoiceLogs"); invoice.UpdateDate = DateTime.Now; invoice.DeveloperID = DeveloperID; //attaching existing invoice. DataContext.InvoiceData.Attach(invoice); //save changes. DataContext.SaveChanges(); //redirect to invoice list. return RedirectToAction("Index"); } And the data access code: public static void Attach(Invoice invoice) { var i = new Invoice { InvoiceID = invoice.InvoiceID }; db.Invoices.Attach(i); db.Invoices.ApplyCurrentValues(invoice); } In the SaveHours action, it properly sets the values of the InvoiceLog entities after I call TryUpdateModel but when it does SaveChanges it doesn't update the database with the new values. Also, if you manually update the values of the InvoiceLog entries in the database and then go to this page it doesn't populate the textboxes so it's clearly not binding correctly. Thanks, Justin

• TableView Cells Use Whole Screen Height

  - by Kyle

  I read through this tutorial Appcelerator: Using JSON to Build a Twitter Client and attempted to create my own simple application to interact with a Jetty server I setup running some Spring code. I basically call a get http request that gives me a bunch of contacts in JSON format. I then populate several rows with my JSON data and try to build a TableView. All of that works, however, my tableView rows take up the whole screen. Each row is one screen. I can scroll up and down and see all my data, but I'm trying to figure out what's wrong in my styling that's making the cells use the whole screen. My CSS is not great, so any help is appreciated. Thanks! Here's my js file that's loading the tableView: // create variable "win" to refer to current window var win = Titanium.UI.currentWindow; // Function loadContacts() function loadContacts() { // empty array "rowData" for table view cells var rowData = []; // create http client var loader = Titanium.Network.createHTTPClient(); // set http request method and url loader.setRequestHeader("Accept", "application/json"); loader.open("GET", "http://localhost:8080/contactsample/contacts"); // run the function when the data is ready for us to process loader.onload = function(){ Ti.API.debug("JSON Data: " + this.responseText); // evaluate json var contacts = JSON.parse(this.responseText); for(var i=0; i < contacts.length; i++) { var id = contacts[i].id; Ti.API.info("JSON Data, Row[" + i + "], ID: " + contacts[i].id); var name = contacts[i].name; Ti.API.info("JSON Data, Row[" + i + "], Name: " + contacts[i].name); var phone = contacts[i].phone; Ti.API.info("JSON Data, Row[" + i + "], Phone: " + contacts[i].phone); var address = contacts[i].address; Ti.API.info("JSON Data, Row[" + i + "], Address: " + contacts[i].address); // create row var row = Titanium.UI.createTableViewRow({ height:'auto' }); // create row's view var contactView = Titanium.UI.createView({ height:'auto', layout:'vertical', top:5, right:5, bottom:5, left:5 }); var nameLbl = Titanium.UI.createLabel({ text:name, left:5, height:24, width:236, textAlign:'left', color:'#444444', font:{ fontFamily:'Trebuchet MS', fontSize:16, fontWeight:'bold' } }); var phoneLbl = Titanium.UI.createLabel({ text: phone, top:0, bottom:2, height:'auto', width:236, textAlign:'right', font:{ fontSize:14} }); var addressLbl = Titanium.UI.createLabel({ text: address, top:0, bottom:2, height:'auto', width:236, textAlign:'right', font:{ fontSize:14} }); contactView.add(nameLbl); contactView.add(phoneLbl); contactView.add(addressLbl); row.add(contactView); row.className = "item" + i; rowData.push(row); } Ti.API.info("RowData: " + rowData); // create table view var tableView = Titanium.UI.createTableView( { data: rowData }); win.add(tableView); }; // send request loader.send(); } // get contacts loadContacts(); And here are some screens showing my problem. I tried playing with the top, bottom, right, left pixels a bit and didn't seem to be getting anywhere. All help is greatly appreciated. Thanks!

• UI android question/problem with Listview

  - by user309554

  Hi, I'm trying to recreate the UI screen called 'My Places' that is used in the Weather Channel app. I'd attach a screenshot of the screen, but I can't seem to do it here. It seems they're using two listviews one on top of the other, but I'm not sure for certain. Could anybody confirm this for me? If they are doing this, how is this done? I've tried to implement this, but without full success. My top listview 'Add a place' 'comes up correctly, but the bottom listview will not appear/populate for me? I shall attach my code so far......

• How to animate an non-closed path with CAShapeLayer?

  - by mystify

  On GitHub you can find an example for CAShapeLayer which animates an path. It animates a pentagon turning into a star. First: This works only in the iPhone simulator. OS 3.0 on the device shows serious bugs with this code. But I can't find anything wrong in there. However, I tried to animate an path which is not closed. To put it simply: A few straight lines. Is there anything special I must do to get this work properly on the device? - (void)loadView { UIView *appView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; appView.backgroundColor = [UIColor blackColor]; self.view = appView; [appView release]; rootLayer = [CALayer layer]; rootLayer.frame = self.view.bounds; [self.view.layer addSublayer:rootLayer]; //Pentagon Path pentagonPath = CGPathCreateMutable(); CGPathMoveToPoint(pentagonPath, nil, 10.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 100.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 110.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 120.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 130.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 310.0f, 270.0f); //CGPathCloseSubpath(pentagonPath); //Star Path starPath = CGPathCreateMutable(); CGPathMoveToPoint(starPath, nil, 10.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 100.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 210.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 220.0f, 260.0f); CGPathAddLineToPoint(starPath, nil, 230.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 310.0f, 270.0f); //CGPathCloseSubpath(starPath); //Create Shape shapeLayer = [CAShapeLayer layer]; //shapeLayer.path = pentagonPath; UIColor *col = [UIColor colorWithWhite:0.9 alpha:1.0]; //shapeLayer.fillColor = col.CGColor; shapeLayer.strokeColor = col.CGColor; shapeLayer.lineWidth = 3.0f; // shapeLayer.contents = [UIImage imageNamed:@"test.png"]; shapeLayer.fillRule = kCAFillRuleEvenOdd; [rootLayer addSublayer:shapeLayer]; [self performSelector:@selector(startAnimation) withObject:nil afterDelay:1.0]; } -(void)startAnimation { CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"path"]; animation.duration = 2.0; animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; animation.repeatCount = 1e100f; animation.autoreverses = YES; animation.fromValue = (id)pentagonPath; animation.toValue = (id)starPath; [shapeLayer addAnimation:animation forKey:@"animatePath"]; } Note this lines, where I just make straight lines with a small peak which is animated: //Pentagon Path pentagonPath = CGPathCreateMutable(); CGPathMoveToPoint(pentagonPath, nil, 10.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 100.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 110.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 120.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 130.0f, 270.0f); CGPathAddLineToPoint(pentagonPath, nil, 310.0f, 270.0f); //CGPathCloseSubpath(pentagonPath); //Star Path starPath = CGPathCreateMutable(); CGPathMoveToPoint(starPath, nil, 10.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 100.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 210.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 220.0f, 260.0f); CGPathAddLineToPoint(starPath, nil, 230.0f, 270.0f); CGPathAddLineToPoint(starPath, nil, 310.0f, 270.0f); I don't want a closed and filled path, but only simple lines with some color and thickness. The nasty thing on the device is, that the first point seems to move towards the right side of the screen for no reason. On the simulator though, it works perfectly fine. Maybe something is wrong with this setup?

• ListView items not responding to tap

  - by Justin Williams

  I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter. The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost - LinearLayout - TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/nearby_no_events" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" android:choiceMode="multipleChoice" android:divider="#d9d9d9" android:dividerHeight="1px" android:cacheColorHint="#eee" /> </LinearLayout> And the relevant code from my Activity that is set to show in the selected tab. public class NearbyActivity extends ListActivity { private ArrayList<Event> m_events = null; private EventAdapter m_adapter = null; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nearby_activity); getEvents(); this.m_adapter = new EventAdapter(this, R.layout.eventrow, m_events); setListAdapter(this.m_adapter); } private void getEvents() { m_events = new ArrayList<Event>(); for (int i = 0; i < 100 ; i++) { Event e = new Event(); e.setEventName("Event " + i); e.setVenueName("Staples Center"); e.setStartDate(new Date()); m_events.add(e); } } private class EventAdapter extends ArrayAdapter<Event> { private ArrayList<Event> items; public EventAdapter(Context context, int textViewResourceId, ArrayList<Event> items) { super(context, textViewResourceId, items); this.items = items; } @Override public View getView (int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.eventrow, null); } Event e = items.get(position); if (e != null) { TextView nameText = (TextView)v.findViewById(R.id.eventName); TextView venueNameText = (TextView)v.findViewById(R.id.venueName); if (nameText != null) { nameText.setText(e.getEventName()); } if(venueNameText != null) { venueNameText.setText(e.getVenueName()); } } return v; } } } My listview row's are populated by an XML file as well. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:orientation="vertical" android:padding="4dip"> <TextView android:id="@+id/eventName" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:inputType="text" android:singleLine="true" android:ellipsize="marquee" android:textSize="18sp" android:textColor="#000" /> <TextView android:id="@+id/venueName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/eventName" android:layout_alignParentBottom="true" android:layout_marginRight="55dip" android:singleLine="true" android:ellipsize="end" android:scrollHorizontally="true" android:textSize="13sp" android:textColor="#313131" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" /> </RelativeLayout> Thanks for any help you can offer.

• Cocoa QuickLook initiated by NSTableView Cell

  - by Tristan Seifert

  I have an NSTableView that contains 2 different Columns - one is an NSImageCell that shows a file icon, and the second is a custom subclass of NSTextFieldCell that contains a quick look button on the right of the text. When I click the Quick Look button, the following code is invoked: [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; This does it's job and shows the blank Quick Look panel saying "No Items Selected." After I did a bit of research on the internet, I implemented a custom NSTableView subclass to be the Delegate and Data Source for the Quick Look panel. I get the notification that Quick Look asks if I want to be the delegate, and I respond with return YES. Even though I implement all methods in both QLPreviewPanelDataSource and QLPreviewPanelDelegate, at runtime I get this error on the console: 2010-12-24 15:32:17.235 BackMeUp[4763:80f] clicked: ~/Desktop/HUDTape.mov 2010-12-24 15:32:17.489 BackMeUp[4763:80f] [QL] QLError(): -[QLPreviewPanel setDelegate:] called while the panel has no controller - Fix this or this will raise soon.

The first line above is just that I know the cell has been clicked. Anyways, here is the .m file of the custom table view subclass: // // BackupListTableView.m // BackMeUp // // Created by Tristan Seifert on 12/24/10. // Copyright 2010 24/7 Server.

• Sharing the model in MVP Winforms App

  - by Keith G

  I'm working on building up an MVP application (C# Winforms). My initial version is at http://stackoverflow.com/questions/1422343/ ... Now I'm increasing the complexity. I've broken out the code to handle two separate text fields into two view/presenter pairs. It's a trivial example, but it's to work out the details of multiple presenters sharing the same model. My questions are about the model: I am basically using a property changed event raised by the model for notifying views that something has changed. Is that a good approach? What if it gets to the point where I have 100 or 1000 properties? Is it still practical at that point? Is instantiating the model in each presenter with   NoteModel _model = NoteModel.Instance   the correct approach? Note that I do want to make sure all of the presenters are sharing the same data. If there is a better approach, I'm open to suggestions .... My code looks like this: NoteModel.cs public class NoteModel : INotifyPropertyChanged { private static NoteModel _instance = null; public static NoteModel Instance { get { return _instance; } } static NoteModel() { _instance = new NoteModel(); } private NoteModel() { Initialize(); } public string Filename { get; set; } public bool IsDirty { get; set; } public readonly string DefaultName = "Untitled.txt"; string _sText; public string TheText { get { return _sText; } set { _sText = value; PropertyHasChanged("TheText"); } } string _sMoreText; public string MoreText { get { return _sMoreText; } set { _sMoreText = value; PropertyHasChanged("MoreText"); } } public void Initialize() { Filename = DefaultName; TheText = String.Empty; MoreText = String.Empty; IsDirty = false; } private void PropertyHasChanged(string sPropName) { IsDirty = true; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sPropName)); } } public event PropertyChangedEventHandler PropertyChanged; } TextEditorPresenter.cs public class TextEditorPresenter { ITextEditorView _view; NoteModel _model = NoteModel.Instance; public TextEditorPresenter(ITextEditorView view)//, NoteModel model) { //_model = model; _view = view; _model.PropertyChanged += new PropertyChangedEventHandler(model_PropertyChanged); } void model_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "TheText") _view.TheText = _model.TheText; } public void TextModified() { _model.TheText = _view.TheText; } public void ClearView() { _view.TheText = String.Empty; } } TextEditor2Presenter.cs is essentially the same except it operates on _model.MoreText instead of _model.TheText. ITextEditorView.cs public interface ITextEditorView { string TheText { get; set; } } ITextEditor2View.cs public interface ITextEditor2View { string MoreText { get; set; } }

• Dynamic Scoped Resources in WPF/XAML?

  - by firoso

  I have 2 Xaml files, one containing a DataTemplate which has a resource definition for an Image brush, and the other containing a content control which presents this DataTemplate. The data template is bound to a view model class. Everything seems to work EXCEPT the ImageBrush resource, which just shows up white... Any ideas?
