  • Checking if a RoutedEvent has any handlers

    - by AK
    I've got a custom Button class, that always performs the same action when it gets clicked (opening a specific window). I'm adding a Click event that can be assigned in the button's XAML, like a regular button. When it gets clicked, I want to execute the Click event handler if one has been assigned, otherwise I want to execute the default action. The problem is that there's apparently no way to check if any handlers have been added to an event. I thought a null check on the event would do it: if (Click == null) { DefaultClickAction(); } else { RaiseEvent(new RoutedEventArgs(ClickEvent, this));; } ...but that doesn't compile. The compiler tells me that I can't do anything other than += or -= to an event outside of the defining class, event though I'm trying to do this check INSIDE the defining class. I've implemented the correct behavior myself, but it's ugly and verbose and I can't believe there isn't a built-in way to do this. I must be missing something. Here's the relevant code: public class MyButtonClass : Control { //... public static readonly RoutedEvent ClickEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonClass)); public event RoutedEventHandler Click { add { ClickHandlerCount++; AddHandler(ClickEvent, value); } remove { ClickHandlerCount--; RemoveHandler(ClickEvent, value); } } private int ClickHandlerCount = 0; private Boolean ClickHandlerExists { get { return ClickHandlerCount > 0; } } //... }

  • Using Moq at Blend design time

    - by adrian hara
    This might be a bit out there, but suppose I want to use Moq in a ViewModel to create some design time data, like so: public class SomeViewModel { public SomeViewModel(ISomeDependency dependency) { if (IsInDesignMode) { var mock = new Mock<ISomeDependency>(); dependency = mock.Object; // this throws! } } } The mock could be set up to do some stuff, but you get the idea. My problem is that at design-time in Blend, this code throws an InvalidCastException, with the message along the lines of "Unable to cast object of type 'Castle.Proxies.ISomeDependencyProxy2b3a8f3188284ff0b1129bdf3d50d3fc' to type 'ISomeDependency'." While this doesn't necessarily look to be Moq related but Castle related, I hope the Moq example helps ;) Any idea why that is? Thanks!

  • Iterating through StaticResource loaded by ResourceDictionary

    - by akaphenom
    Given a resource dictionary loading some static resources into memory - is there any way to iterate through theResources loaded into memory? My silverlight application keeps telling me it cannot find a static resource. I wonder if I have a naming convention issue or somehting - was hoping iterating through the resources in memory would help diagnose any issue... I have the following app.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> and content template: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary>

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • How to aggregate bindings in Silverlight UserControl

    - by Peter Wone
    Imagine a UserControl containing some sort of ItemsControl. The UserControl as a whole has a DataContext, but you also need to expose the ItemsSource of the ItemsControl. I have tried all manner of arrangements, and eventually passed a DomainDataSource as a UserControl dependency property named DDS, and bound the ItemsControl like this: ItemsSource="{Binding DDS.Data, ElementName=userControl}" It works, but this is mucky, and with Silverlight mucky is nearly always a sign of incorrect approach. Your advice is sought. It looks like multi-bindings might be the answer to this.

  • Multibinding File-Paths into a Button ControlTemplate

    - by Bill
    I am trying to develop an application that uses a number of images that are stored in a seperate remote file location. The file-paths to the UI elements are stored within the Application Settings. Although I understand how to access the images from Applications Settings using a MultiBinding and a value converter, I'm not sure how to integrate the Multibinding into the ImageButton ControlTemplate below. Can anyone steer me in the right direction? <Image.Source> <MultiBinding Converter="{StaticResource MyConverter}"> <Binding Source="{StaticResource Properties.Settings}" Path="Default.pathToInterfaceImages" /> <Binding Source="ScreenSaver.png"></Binding> </MultiBinding> </Image.Source> <Button Click="btn_ScreenSaver_Click" Style="{DynamicResource ThreeImageButton}" local:ThreeImageButton.Image="C:\Skins\ScreenSaver_UP.png" local:ThreeImageButton.MouseOverImage="C:\Skins\ScreenSaver_OVER.png" local:ThreeImageButton.PressedImage="C:\Skins\ScreenSaver_DOWN.png"/> <Style x:Key="ThreeImageButton" TargetType="{x:Type Button}"> <Setter Property="FontSize" Value="10"/> <Setter Property="Height" Value="34"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <StackPanel Orientation="Horizontal" > <Image Name="PART_Image" Source= "{Binding Path=(local:ThreeImageButton.Image), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}" /> </StackPanel> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Source" Value="{Binding Path=(local:ThreeImageButton.MouseOverImage), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}" TargetName="PART_Image"/> </Trigger> <Trigger Property="IsPressed" Value="True"> <Setter Property="Source" Value="{Binding Path=(local:ThreeImageButton.PressedImage), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}" TargetName="PART_Image"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Source" Value="{Binding Path=(local:ThreeImageButton.Image), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}" TargetName="PART_Image"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> public class ThreeImageButton : DependencyObject { // Add three new Dependency Properties to the Button Class to hold the // path to each of the images that are bound to the control, displayed // during normal, mouse-over and pressed states. public static readonly DependencyProperty ImageProperty; public static readonly DependencyProperty MouseOverImageProperty; public static readonly DependencyProperty PressedImageProperty; public static ImageSource GetImage(DependencyObject obj) { return (ImageSource)obj.GetValue(ImageProperty); } public static ImageSource GetMouseOverImage(DependencyObject obj) { return (ImageSource)obj.GetValue(MouseOverImageProperty); } public static ImageSource GetPressedImage(DependencyObject obj) { return (ImageSource)obj.GetValue(PressedImageProperty); } public static void SetImage(DependencyObject obj, ImageSource value) { obj.SetValue(ImageProperty, value); } public static void SetMouseOverImage(DependencyObject obj, ImageSource value) { obj.SetValue(MouseOverImageProperty, value); } public static void SetPressedImage(DependencyObject obj, ImageSource value) { obj.SetValue(PressedImageProperty, value); } // Register each property with the control. static ThreeImageButton() { var metadata = new FrameworkPropertyMetadata((ImageSource)null); ImageProperty = DependencyProperty.RegisterAttached("Image", typeof(ImageSource), typeof(ThreeImageButton), metadata); var metadata1 = new FrameworkPropertyMetadata((ImageSource)null); MouseOverImageProperty = DependencyProperty.RegisterAttached("MouseOverImage", typeof(ImageSource), typeof(ThreeImageButton), metadata1); var metadata2 = new FrameworkPropertyMetadata((ImageSource)null); PressedImageProperty = DependencyProperty.RegisterAttached("PressedImage", typeof(ImageSource), typeof(ThreeImageButton), metadata2); } }

  • Displaying FontFamily in Combobox

    - by Torsten
    Hi. My goal is to manipulate the text-styles of my application via DependencyProperties. I got a diagram in which the texts are to be manipulated in size, fontfamily, color, etc. So I'd like to use an interface similar to a rich text editor like Word. I'm using this code in my TextStyleVM http://shevaspace.blogspot.com/2006/12/i-have-some-fun-with-formattedtext_14.html So I have a FontFamilyProperty and a Getter and Setter for it: public static DependencyProperty FontFamilyProperty = DependencyProperty.Register( "FontFamily", typeof(FontFamily), typeof(OutlinedText), new FrameworkPropertyMetadata( SystemFonts.MessageFontFamily, FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.AffectsMeasure), new ValidateValueCallback(IsValidFontFamily)); public FontFamily FontFamily { get { return (FontFamily)base.GetValue(FontFamilyProperty); } set { base.SetValue(FontFamilyProperty, value); } } Then there is a ToStyle method, which sets the style for the labels of the diagram, which are to be manipulated: Style style = new Style(); Binding fontFamilyBinding = new Binding("FontFamily"); fontFamilyBinding.Source = this; Setter fontFamilySetter = new Setter(); fontFamilySetter.Property = TextBlock.FontFamilyProperty; fontFamilySetter.Value = fontFamilyBinding; style.Setters.Add(fontFamilySetter); return style; Now this works for a TextBox. The textbox displays the current FontFamily, and if I enter a new, valid FontFamily like Arial into the textbox the FontFamily of the labels are changed. However, what I'd like to have is a combobox, which displays the SystemFonts and where I can choose one FontFamily for my labels. However, the binding doesn't seem to work. Neither the system fonts nor the current fonts of the labels are displayed. The combobox is just empty. This is my xaml: <r:RibbonLabel Content="FontFamily" /> <!--these do not work--> <r:RibbonComboBox SelectedItem="{Binding FontFamily}"/> <r:RibbonComboBox ItemsSource="{Binding FontFamily}"/> <!--this works--> <r:RibbonTextBox Text="{Binding FontFamily}"/> Now, I assume I have to set a different Setter for a ComboBox in the ToStyle Method. But I have no clue, which one. Maybe someting like this: fontFamilySetter.Property = ComboBox.ItemSource; However, if I set that Property, the TextBox still works. So is this the wrong place to start at? I'd also be grateful if someone could hint me to some documentation about using these Style-, Setter-, Binding-key-words, which are used in the ToStyle method, since this is somebody elses code I'm working with.

  • ICommand.CanExecute being passed null even though CommandParameter is set...

    - by chaiguy
    I have a tricky problem where I am binding a ContextMenu to a set of ICommand-derived objects, and setting the Command and CommandParameter properties on each MenuItem via a style: <ContextMenu ItemsSource="{Binding Source={x:Static OrangeNote:Note.MultiCommands}}"> <ContextMenu.Resources> <Style TargetType="MenuItem"> <Setter Property="Header" Value="{Binding Path=Title}" /> <Setter Property="Command" Value="{Binding}" /> <Setter Property="CommandParameter" Value="{Binding Source={x:Static OrangeNote:App.Screen}, Path=SelectedNotes}" /> ... However, while ICommand.Execute( object ) gets passed the set of selected notes as it should, ICommand.CanExecute( object ) (which is called when the menu is created) is getting passed null. I've checked and the selected notes collection is properly instantiated before the call is made (in fact it's assigned a value in its declaration, so it is never null). I can't figure out why CanEvaluate is getting passed null.

  • help with grouping and sorting for TreeView in xaml

    - by danhotb
    I am having problems getting my head around grouping and sorting in xaml and hope someone can get me straightened out! I have creaed an xml file from a tree of files and folders (just like windows explorer) that can be serveral levels deep. I have bound a TreeView control to an xml datasource and it works great! It sorts everything alphabetically but ... I would like it to sort all folders first then all files, rather than folders listed with files, as it does now. the xml : if you load this to a treeviw it will display the two files before the folder because they are first in alpha-order. here is my code: <!-- This will contain the XML-data. --> <XmlDataProvider x:Key="xmlDP" XPath="*"> <x:XData> <Select_Project /> </x:XData> </XmlDataProvider> <!-- This HierarchicalDataTemplate will visualize all XML-nodes --> <HierarchicalDataTemplate DataType="project" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="folder" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="file" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <CollectionViewSource x:Key="projectView" Source="{StaticResource xmlDP}"> <CollectionViewSource.SortDescriptions> <!-- ADD SORT DESCRIPTION HERE --> </CollectionViewSource.SortDescriptions> </CollectionViewSource> <TreeView Margin="11,79.992,18,19.089" Name="tvProject" BorderThickness="1" FontSize="12" FontFamily="Verdana"> <TreeViewItem ItemsSource="{Binding Source={StaticResource xmlDP}, XPath=*}" Header="Project"/> </TreeView>

  • implement INotifyCollectionChanged etc on xml file changed

I have that code to filter and bind xml data to list box: XmlDocument channelsDoc = new XmlDocument(); channelsDoc.Load("RssChannels.xml"); XmlNodeList channelsList = channelsDoc.GetElementsByTagName("channel"); this.RssChannelsListBox.DataContext = channelsList;

  • Can the MVVM-Light ViewModelLocator be used in nested ViewModels?

    - by dthrasher
    The Visual Studio 2008 Designer doesn't seem to like UserControls that reference the MVVM-Light ViewModelLocator. I get an error message like: Could not create an instance of type 'MyUserControl'. For example, the following XAML will cause this behavior if MyUserControl uses the ViewModelLocator to establish its DataContext. <Page x:Class="MyProject.Views.MainView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Views="clr-namespace:MyProject.Views" > <Grid> <Views:MyUserControl/> </Grid> </Page> Is the ViewModelLocator only meant to be used in top-level Views?

  • Inheriting from DataGridTextColumn and overriding GenerateElement

    - by philbrowndotcom
    I'm attempting to create a custom DataGrid where I can format individual cells based on the cell value (ie; red text for negative values, green for postitive) ala this approach... http://stackoverflow.com/questions/686165/how-to-get-binding-value-of-current-cell-in-a-wpftoolkit-datagrid I also need to convert the values from negative to parenthesised (ie; -2.34 to (2.34)). I've got the inheritance/overide working. My question is, how do I get access to the values in the cells in the overridden GenerateElement method. Thanks in advance, Phil

  • CSS: Aligning problem with rounded corners in IE 6/7 but ok in IE8/ Firefox etc

    - by mark smith
    Hi there, can anyone help? I have a problem aligning rounded corners in IE6/7. Basically everything seems to work in Firefox / IE8 but in IE6/7 the left / center / and right divs get misaligned. This basically shows exactly what i am refering to. here is the example in IE8 and everything works ok http://es.drop.io/ern0fye/asset/ie8-jpg And here is the problem (this example is running in IE8 with compat mode set to IE7) http://es.drop.io/ern0fye/asset/ie7-jpg I seem to remember there being a bug in IE6/7 with lineheight or similar but i don't recall exactly. I will paste the CSS and HTML below it is very very simple. Basically there is a left div that holds the left corner image and center div which has a background of RED which is the same as the corner images and finally a right div which holds the right corner image. I would appreciate any input anyone has. Thanks in advance. Here is the CSS .vl-top-left { float:left; width:12px; height:12px; } .vl-top-center { float:left; width: 485px; background-color: #F04A23; height:12px; } .vl-top-right { float:left; height:12px; width:12px; } and the HTML is :- <!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> <title></title> <link href="Stylesheet1.css" rel="stylesheet" type="text/css" /> </head> <body> <div class="vl-top-left"> <img src="content/images/esquina_sup_izq.gif" width="12" height="12"> </div> <div class="vl-top-center"> &nbsp; </div> <div class="vl-top-right"> <img src="content/images/esquina_sup_der.gif" width="12" height="12"> </div> </body> </html> EDIT Applied also margin:0 and padding:0 on the body and on each DIV but still the left and right div drops down as per the screenshot

  • Getting overflow-y:scroll to work with fixed positioning html & css

    - by Vagabond_King
    I have a Jquery tools scrollable thats set to be fixed to the bottom of the browser window. Ideally i would just like to get a overflow-y:scroll; working for the page as a whole when the browser is < 700px. (so no content gets hidden, as its all fixed place). This feels like it should be simple but its causing me huge headaches. js solutions are fine at this point. Thanks in advance. <body> <div id="background"> <div id="fix_to_floor"> <div class="scrollable"> <div class="frame"> <div class="page" id="page1"> <div class="inner_page"> <h2>About Us</h2> <p>content</p> <div class="floor_items"> <img src="images/chair_n_hole.png" width="950" height="700" alt="Chair N Hole"> </div> </div> </div> <div class="page" id="page2"> <div class="inner_page"> <h2>page 2</h2> <p>content</p> <div class="floor_items"> <img src="images/spachairs.png" width="950" height="700" alt="Spachairs"> </div> </div> </div> <div class="page" id="page3"> <div class="inner_page"> <span class="copy"> <h2>Products</h2> </span> </div> </div> </div> </div> </div> </div> </body> body { width: 100%; bottom:0px; position: fixed; } div#background{ height:948px; width:100%; background: #DDD url('../images/working_bg.jpg') repeat-x fixed bottom center; bottom:0px; overflow: scroll; } div#fix_to_floor{ position: fixed; margin: 0 auto; bottom:0px; height: 700px; width: 1700px; } .content img{ position: absolute; bottom: 0; } #content div.floor_items{ position: absolute; bottom:0; width:1700px; width: 950px; height: 700px; } /* **** specific page backgrounds */ /* page 3 - Products */ #page3 .inner_page{ background: url('../images/display.png') no-repeat scroll bottom center; z-index: 50; } #page3 .copy{ float: left; margin: 100px 300px; } #page1 div.floor_items img{ margin: 0 0 0 0px; } /********* SCROLLABLE *********/ div.scrollable{ bottom: 0; position: relative; /* required*/ overflow:hidden; width:1700px; height: 700px; left:0px; } /* needs to be huge and fixed. holds the content */ div.scrollable div.frame{ width: 20000em; position: absolute; height: 700px; } /* single item , must bve floated for horiz. scrolling*/ div.frame div.page{ float:left; width: 1700px; height: 700px; margin: 0; } div.page div.inner_page{ width:950px; height:700px; margin: 0 370px; /* border: 1px solid red;*/ }

  • CSS - margin and float property

    - by David Casillas
    1.- We have a div with static positioning. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph without the margin 2.- We have a div with float:left. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph plus its margin. What is the explanation of this? Here is the html code and the CSS code. And here is a link to the test site. http://prueba.davidcasillas.es/ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <link href="index.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="nivel1"> <div id="nivel21"> <p>Este es el primer parrafo</p> </div> <div id="nivel22"> <p>Este es el primer parrafo</p> </div> </div> </body> </html> body { margin:0; padding:0; } #nivel1 { border:solid; border-color:#333; margin:0; background-color:#0F3; margin:2em; } #nivel21 { margin:2em; float:left; background-color:#C00; } #nivel22 { margin:2em; background-color:#FC0; }
