  • help with eclipse debugging /or/ subclassed SimpleAdapter not calling setViewImage()

    - by edzillion
    Hi I was following the method for asynchronously loading images into a listview as outlined in evan charlton's blog here. The problem I am having is that the setViewImage function is not being called by the system: @Override public void setViewImage(final ImageView image, final String value) { if (value != null && value.length() > 0 && image instanceof RemoteImageView) { RemoteImageView riv = (RemoteImageView) image; riv.setLocalURI(API.getCacheFileName(value)); riv.setRemoteURI(value); super.setViewImage(image, R.drawable.icon); } else { image.setVisibility(View.GONE); } } I have built his example code, and setViewImage is called fine - it seems to me that the code is functionally identical. Looking into the docs it says: First, if a SimpleAdapter.ViewBinder is available, setViewValue(android.view.View, Object, String) is invoked. If the returned value is true, binding has occured. If the returned value is false and the view to bind is a TextView, setViewText(TextView, String) is invoked. If the returned value is false and the view to bind is an ImageView, setViewImage(ImageView, int) or setViewImage(ImageView, String) is invoked. If no appropriate binding can be found, an IllegalStateException is thrown. I don't really understand how to debug (in eclipse) to find out how this process is occuring, advice on how to do so would be a help. Thanks.

  • UserControl as ListBoxItem and IsSelected

    - by mattjf
    I have a usercontrol that I want to use as a ListBoxItem. <ListBox.ItemTemplate> <DataTemplate> <local:MyUserControl/> </DataTemplate> </ListBox.ItemTemplate> I'd like to play a storyboard when the usercontrol is unselected. <UserControl.Resources> <Style TargetType="{x:Type UserControl}"> <Style.Triggers> <DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}, Mode=FindAncestor}}" Value="False"> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource OnMouseLeaveSB}"/> </DataTrigger.EnterActions> </DataTrigger> </Style.Triggers> </Style> </UserControl.Resources> But the storyboard is never firing. Is there a better way to do this? Edited to Add: What I am really trying to accomplish this this: When the mouse is over the UserControl, I want to play a storyboard (OnMouseEnterSB). When the mouse leaves the UserControl, I want to play another storyboard (OnMouseLeaveSB). I have all this working fine. When the UserControl is selected, however, and the mouse leaves, I do NOT want to play the storyboard. Finally, when the UserControl is unselected, I want to play the OnMouseLeaveSB storyboard.

  • How do you replace an entire xaml element?

    - by luke
    <ListView> <ListView.Resources> <DataTempalte x:Key="label"> <TextBlock Text="{Binding Label}"/> </DataTEmplate> <DataTemplate x:Key="editor"> <UserControl Content="{Binding Control.content}"/> <!-- This is the line --> </DataTemplate> </ListView.Resources> <ListView.View> <GridView> <GridViewColumn Header="Name" CellTemplate="{StaticResource label}"/> <GridViewColumn Header="Value" CellTemplate="{StaticResource editor}"/> </GridView> </ListView.View> On the marketed line, I'm replacing the contents of a UserControl with the contents of another UserControl that is dynamically created in code. I'd like to replace the entire control, and not just the content. Is there a way to do this?

  • How to restart a wcf server from within a client?

    - by djerry
    Hey guys, I'm using Wcf for server - client communication. The server will need to run as a service, so there's no GUI. The admin can change settings using the client program and for those changes to be made on server, it needs to restart. This is my server setup NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://localhost:8000"); //_svc = new ServiceHost(typeof(MonitoringSystemService), address); _monSysService = new MonitoringSystemService(); _svc = new ServiceHost(_monSysService, address); publishMetaData(_svc, "http://localhost:8001"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); MonitoringSystemService is a class i'm using to handle client - server comm. It looks like this: [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, MaxItemsInObjectGraph = 2147483647)] public class MonitoringSystemService : IMonitoringSystemService {} So i need to call a restart method on the client to the server, but i don't know how to restart (even stop - start) the server. I hope i'm not missing any vital information. Thanks in advance.

  • What do you need to implement to provide a Content Set for an NSArrayController?

    - by whuuh
    Heys, I am writing something in Xcode. I use Core Data for persistency and link the view and the model together with Cocoa Bindings; pretty much your ordinary Core Data application. I have an array controller (NSArrayController) in my Xib. This has its managedObjectContext bound to the AppDelegate, as is convention, and tracks an entity. So far so good. Now, the "Content Set" biding of this NSArrayController limits its content set (as you'd expect), by a keyPath from the selection in another NSArrayController (otherAc.selection.detailsOfMaster). This is the usual way to implement a Master-Detail relationship. I want to variably change the key path at runtime, using other controls. This way, I sould return a content set that includes several other content sets, which is all advanced and beyond Interface Builder. To achieve this, I think I should bind the Content Set to my AppDelegate instead. I have tried to do this, but don't know what methods to implement. If I just create the KVC methods (objectSet, setObjectSet), then I can provide a Content Set for the Array Controller in the contentSet method. However, I don't think I'm binding this properly, because it doesn't "refresh". I'm new to binding; what do I need to implement to properly update the Content Set when other things, like the selection in the master NSArrayController, changes?

  • Can't get focus on a TextBox inside a ListBox using Silverlight

    - by Steve Temple
    I'm having a little trouble in silverlight with a listBox containing databound textBox elements. The items display correctly in the list and the textBox is populated correctly but I can't get focus on the text box in the list. If I hover over the edges of the textBox it highlights but it won't let me click into it to edit the text. Any ideas? My XAML looks like this: <ListBox x:Name="listImages"> <ListBox.ItemTemplate> <DataTemplate> <Grid x:Name="LayoutRoot" Background="White"> <Image Height="102" HorizontalAlignment="Left" Name="imgThumb" Stretch="UniformToFill" VerticalAlignment="Top" Width="155" Source="{Binding ImageFilename, Converter={StaticResource ImageConverter}}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="154,25,0,0" Name="txtAltText" VerticalAlignment="Top" Width="239" Text="{Binding Alt}" /> <dataInput:Label Height="19" HorizontalAlignment="Left" Margin="154,6,0,0" Name="lblAltText" VerticalAlignment="Top" Width="239" Content="Alt Text" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

  • In JSF - What is the correct way to do this? Two dropdown lists with dependency.

    - by Ben
    Hi, I'm making two dropdown lists in JSF which are dependent. Specifically, one list has all the languages and the second list contains values that are displayed in the currently selected language. I've implemented this by having the second list use information from a Hash and rebuilding that Hash in the setter of the currently selected language. JSF Code Bit: <rich:dropDownMenu value="#{bean.currentlySelectedLanguage}" id="languageSelector"> ... (binding to languages hash) ... <rich:dropDownMenu value="#{bean.currentlySelectedScript}" id="ScriptPullDown"> ... (binding to scripts hash) ... Backing Bean Code Bit: setCurrentlySelectedLanguage(String lang){ this.currentlySelectedLanguage = lang; rebuildScriptNames(lang); } I'm wondering if that's a good way of doing this or if theres a better method that I am not aware of. Thank you! EDIT - Adding info.. I used a a4j:support that with event="onchange" and ReRender="ScriptPullDown" to rerender the script pull down. I could probably add an action expression to run a method when the value changes. But is there a benefit to doing this over using code in the setter function?

  • WPF Notify changes on object

    - by Erik Z
    I have a gridview were I define some columns, like this... <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding MyProp}" /> </DataTemplate> </GridViewColumn.CellTemplate> I bind my gridview to a collection and implemts INotifyPropertyChanged in the property MyProp. This works well and any changes of MyProp are reflected to the gridview. If I add another column that is bound to the object itself I dont get any notifications/updates. My code... <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Converter={StaticResource myConverter}}"/> </DataTemplate> </GridViewColumn.CellTemplate> I think I need something like INotifyPropertyChanged for the object but I have no idea how to do this. Any suggestions?

  • SL3 Nav framework + MVVM ligh

    - by Murari
    Hi All, Thanks for taking time to read through my question. Any guidance is really appreciated. I am using SL3 Navigation framework in my LOB application. I m currently using MVVM Light as the framework guidance. I have a datagrid consisting of employees and when the "user" clicks on "employee id link" in the datagrid, i am transferring the user to "Edit Page". I would like to transfer the "employee id" as query parameter to "edit page". The issue here is: I can access the query parameter in the EditStaffView.xaml.cs - which i don't want to do. protected override void OnNavigatedTo(NavigationEventArgs e) { if (this.NavigationContext.QueryString.ContainsKey("staffcode")) { string title = this.NavigationContext.QueryString["staffcode"]; } } I would like to retrieve the query parameter in my viewmodel and based on the query parameter, i will perform certain operations. When the constructor is called I would like the "view" to pass the staffid as shown below public EditStaffViewModel(int staffId) { LoadData(staffId); } I am constructing my hyperlink buttons in the datagrid dyanmically as shown below: staffListingModel.HyperlinkNavigationUri = string.Format("{0}{1}", NavigationUri.DataEntryEditStaff,"?staffcode={" + staffListingModel.StaffCode + "}"); and XAML looks HyperlinkButton Content="{Binding StaffCode,Mode=TwoWay}" NavigateUri="{Binding HyperlinkNavigationUri}" HyperlinkButton Any idea how to do this ?? Thanks for the help. Murari

  • Bind button visibility to the expresion (C#)

    - by drasto
    I have a delete button in each row of GridView (component ASP.NET). I want some of the delete buttons to be invisible. The visibility of the delete button should depend on the data that are back the row. GridView is backed by EntityDataSource. GridView displays entities called Category, one instance in each row. Entity Category has (besides others) also a field of type EntityCollection. Name of that field is Items. Basically I want to allow user to delete a row only if the Items field of backing Category entity is an empty collection. I cannot make up the binding of Visible property. I have no experience with bindings and Google does not really help. This is how the button looks right now: <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="Delete" Visible=??? ></asp:Button> I don't know what should replace ???. The button schold be visible only when this expression evaluates to true: ((SimpleEShop.Model.Category) dataItem).Items.LongCount() <= 0 where dataItem variable contains data of current row in the table. What is the binding that I need ?

  • How to tell which dataform button ended edit when using EventToCommand

    - by Rodd
    I'm new to SilverLight and Mvvm-Light. I have a DataForm on my view that displays/edits a SelectedPerson property (a Person object) of my view model. I want to execute a command on my viewmodel when the user clicks the Save button but don't want to take action if the user clicks cancel. I added the following to my ViewModel: public RelayCommand PersonEditEnded {get; set;} ... public void Initialize() { PersonEditEnded = new RelayCommand(DoSomething); ... } public void DoSomething() { } I added the following to my View: <toolkit:DataForm x:Name="PersonForm" ... CurrentItem="{Binding SelectedPerson, Mode=TwoWay}"> <i:Interaction.Triggers> <i:EventTrigger EventName="EditEnded"> <gs:EventToCommand Command="{Binding PersonEditEnded, Mode=OneWay}"/> </i:EventTrigger> </i:Interaction.Triggers> </toolkit:DataForm> This works and the DoSomething method is being called when the user presses Submit. However, DoSomething is also called when user presses Cancel. Is there a way to know which button was pressed or to supress the call when Cancel is pressed? Thanks for whatever help you can offer!

  • Publishing a WCF Server and client and their endpoints

    - by Ahmadreza
    Imagine developing a WCF solution with two projects (WCF Service/ and web application as WCF Client). As long as I'm developing these two projects in visual studio and referencing service to client (Web Application) as server reference there is no problem. Visual studio automatically assign a port for WCF server and configure all needed configuration including Server And Client binging to something like this in server: <service behaviorConfiguration="DefaultServiceBehavior" name="MYWCFProject.MyService"> <endpoint address="" binding="wsHttpBinding" contract="MYWCFProject.IMyService"> <identity> <dns value="localhost" /> </identity> </endpoint> <host> <baseAddresses> <add baseAddress="http://localhost:8731/MyService.svc" /> </baseAddresses> </host> </service> and in client: <client> <endpoint address="http://localhost:8731/MyService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMyService" contract="MyWCFProject.IMyService" name="WSHttpBinding_IMyService"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> The problem is I want to frequently publish this two project in two different servers as my production servers and Service url will be "http://mywcfdomain/MyService.svc". I don't want to change config file every time I publish my server project. The question is: is there any feature in Visual Studio 2008 to automatically change the URLs or I have to define two different endpoints and I set them within my code (based on a parameter in my configuration for example Development/Published).

  • WPF - Centering a checkbox in a GridViewColumn?

    - by Sonny Boy
    Hey all, I'm currently struggling on getting my checkboxes to property center within my GridViewColumns. I've defined a style for my checkboxes like so: <Style TargetType="{x:Type CheckBox}" x:Key="DataGridCheckBox"> <Setter Property="HorizontalAlignment" Value="Center" /> <Setter Property="HorizontalContentAlignment" Value="Center" /> <Setter Property="IsEnabled" Value="False" /> <Setter Property="Margin" Value="4" /> <Setter Property="VerticalAlignment" Value="Center" /> <Setter Property="VerticalContentAlignment" Value="Center" /> <Setter Property="Width" Value="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type GridViewColumn}},Path=ActualWidth}" /> </Style> And my checkboxes are added into the GridViewColumn using a DataTemplate like this: <GridViewColumn Header="Comment"> <GridViewColumn.CellTemplate> <DataTemplate> <CheckBox Style="{StaticResource DataGridCheckBox}" IsChecked="{Binding PropertyItem.Comment, Converter={StaticResource booleanConverter}, ConverterParameter='string'}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> But the problem I have is that the checkboxes remain left-aligned (even when resizing the column). Any ideas? Thanks in advance, Sonny

  • First test of a Windows Phone application

    - by Maurizio Reginelli
    I downloaded the Microsoft Visual Studio 2010 Express for Windows Phone and I wrote a simple application to make a first test of the emulator. In this application I have only a button with the property Content binded to a string called ButtonText and with the property Background binded to a SolidColorBrush named FillColor. I handled the Click event with this code: void MyButton_Click(object sender, RoutedEventArgs e) { if (toggle == true) { ButtonText = "Blue"; FillColor = new SolidColorBrush(Colors.Blue); } else { ButtonText = "Red"; FillColor = new SolidColorBrush(Colors.Red); } toggle = !toggle; } Unfortunately this doesn't work. While the Content of the Button changes each time the button is pressed, I cannot say the same for the Background which remains at the same color. Could you tell me what is wrong? Thank you. I also post the XAML: <Grid x:Name="ContentGrid" Grid.Row="1"> <Button Name="MyButton" Width="300" Height="300" Content="{Binding Path=ButtonText}" Background="{Binding Path=FillColor}" /> </Grid>

  • C++0x rvalue references and temporaries

    - by Doug
    (I asked a variation of this question on comp.std.c++ but didn't get an answer.) Why does the call to f(arg) in this code call the const ref overload of f? void f(const std::string &); //less efficient void f(std::string &&); //more efficient void g(const char * arg) { f(arg); } My intuition says that the f(string &&) overload should be chosen, because arg needs to be converted to a temporary no matter what, and the temporary matches the rvalue reference better than the lvalue reference. This is not what happens in GCC and MSVC. In at least G++ and MSVC, any lvalue does not bind to an rvalue reference argument, even if there is an intermediate temporary created. Indeed, if the const ref overload isn't present, the compilers diagnose an error. However, writing f(arg + 0) or f(std::string(arg)) does choose the rvalue reference overload as you would expect. From my reading of the C++0x standard, it seems like the implicit conversion of a const char * to a string should be considered when considering if f(string &&) is viable, just as when passing a const lvalue ref arguments. Section 13.3 (overload resolution) doesn't differentiate between rvalue refs and const references in too many places. Also, it seems that the rule that prevents lvalues from binding to rvalue references (13.3.3.1.4/3) shouldn't apply if there's an intermediate temporary - after all, it's perfectly safe to move from the temporary. Is this: Me misreading/misunderstand the standard, where the implemented behavior is the intended behavior, and there's some good reason why my example should behave the way it does? A mistake that the compiler vendors have somehow all made? Or a mistake based on common implementation strategies? Or a mistake in e.g. GCC (where this lvalue/rvalue reference binding rule was first implemented), that was copied by other vendors? A defect in the standard, or an unintended consequence, or something that should be clarified?

  • Why does resolveBinding() return null even though I setResolveBindings(true) on my ASTParser?

    - by Woody Zenfell III
    I am writing an Eclipse plug-in that uses JDT AST's ASTParser to parse a method. I am looking within that method for the creation of a particular type of object. When I find a ClassInstanceCreation, I call getType() on it to see what type is being instantiated. I want to be sure that the fully-resolved type being dealt with there is the one I think it is, so I tell the resultant Type object to resolveBinding(). I get null back even though there are no compilation errors and even though I called setResolveBindings(true) on my ASTParser. I gave my ASTParser (via setSource()) the ICompilationUnit that contains my method, so the parser has access to the entire workspace context. final IMethod method = ...; final ASTParser parser = ASTParser.newParser(AST.JLS3); parser.setResolveBindings(true); parser.setSource(method.getCompilationUnit()); parser.setSourceRange(method.getSourceRange().getOffset(), method.getSourceRange().getLength()); parser.setKind(ASTParser.K_CLASS_BODY_DECLARATIONS); final TypeDeclaration astRoot = (TypeDeclaration) parser.createAST(null); final ClassInstanceCreation classInstanceCreation = walkAstAndFindMyExpression(astRoot); final Type instantiatedType = classInstanceCreation.getType(); System.out.println("BINDING: " + instantiatedType.resolveBinding()); Why does resolveBinding() return null? How can I get the binding information?

  • Set form MinWidth and MinHeight based on child property

    - by Jon Mitchell
    I'm writing an application in WPF using the MVVM pattern. In my application I've got an IPopupWindowService which I use to create a popup dialog window. So to show a ViewModel in a popup window you'd do something like this: var container = ServiceLocator.Current.GetInstance<IUnityContainer>(); var popupService = container.Resolve<IPopupWindowService>(); var myViewModel = container.Resolve<IMyViewModel>(); popupService.Show((ViewModelBase)myViewModel); This is all well and good. What I want to do is be able to set the MinHeight and MinWidth on the View bound to myViewModel and have the popup window use those settings so that a user cannot make the window smaller than its contents will allow. At the moment when the user shrinks the window the contents stops resizing but the window doesn't. EDIT: I map my Views to my ViewModels in ResourceDictionarys like so: <DataTemplate DataType="{x:Type ViewModels:MyViewModel}"> <Views:MyView /> </DataTemplate> And my popup view looks like this: <Window x:Class="TheCompany.Cubit.Shell.Views.PopupWindowView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" SizeToContent="WidthAndHeight" WindowStartupLocation="CenterOwner"> <DockPanel x:Name="panelContent"> <StackPanel HorizontalAlignment="Right" DockPanel.Dock="Bottom" Orientation="Horizontal" Visibility="{Binding RelativeSource={RelativeSource AncestorType=Window},Path=ButtonPanelVisibility}"> <Button Width="75" IsDefault="True" x:Uid="ViewDialog_AcceptButton" Click="OnAcceptButtonClick" Margin="4">OK</Button> <Button Width="75" IsCancel="True" x:Uid="ViewDialog_CancelButton" Click="OnCancelButtonClick" Margin="0,4,4,4">Cancel</Button> </StackPanel> <ContentPresenter Content="{Binding}" /> </DockPanel>

  • How can I change the visibility of elements inside a DataTemplate when a row is selected in a Silver

    - by miketrash
    I'm using the MVVM pattern. I've bound my items and I want to only show the edit button when a row is selected in the datagrid. It appears to be possible with triggers in WPF but we don't have triggers in Silverlight. I tried a TemplatedParent binding but I'm not sure what the TemplatedParent is in this case. We don't have RelativeSource ancestor in Silverlight either. At this point I'm going to look at a solution using the code behind... <data:DataGrid.Columns> <data:DataGridTemplateColumn IsReadOnly="True" Header="Name" Width="300"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid> <TextBlock x:Name="textBlock" Text="{Binding Name, Mode=OneWay}" VerticalAlignment="Center" Margin="4,4,0,4"/> <Button Margin="1,1,4,1" HorizontalAlignment="Right" VerticalAlignment="Center" Padding="7,4" Content="Edit" /> </Grid> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns>

  • How to define a default tooltip style for all Controls

    I would like to define a style with a template when there are validation errors and would display the first error message as a tooltip.

  • Set ContentTemplate in CodeBehind: XamlParseException 2260 Error

    - by user362215
    Hi, I'd like to change the ContentTemplate of a ContentPresenter in the CodeBehind file. But if I run the Silverlight 4 application a XamlParseException with the error code 2260 occures. foreach (ContentPresenter item in Headers) { item.ContentTemplate = Parent.UnselectedHeaderTemplate; } if ((index >= 0) && (index < Headers.Count)) { ContentPresenter item0 = (ContentPresenter)Headers[index]; item0.ContentTemplate = Parent.SelectedHeaderTemplate; } If I do only the foreach code without the code in the "if", it works. And if I only do the code in the "if" without the foreach it works too. But togheter (the "if"-code and the foreach-code) it doesn't work. I have no idea why it doesn't work. The two templates look like this: <Setter Property="UnselectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="#FF999999" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> <!-- SelectedHeader template --> <Setter Property="SelectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="{TemplateBinding Foreground}" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> If you have an idea what problem is please tell me.

  • How can I load combo box's data when it has been defined in DataTemplate codebehind ?

    - by Naseem
    Hi, In my silverlight application,I need to have dynamic columns in my DataGrid . So I had to create all the columns and their DataTemplate dynamically .When user wants to edit the column , a combo box will be displayed which has different values based on selected column. For creating each column I have wrote : foreach (var itemFilter in ProductFilterCollection) { DataGridTemplateColumn templateColumn = new DataGridTemplateColumn(); templateColumn.Header = itemFilter.Description.ToString(); templateColumn.CellTemplate = CreateCellTemplate(typeof(TextBlock), itemFilter.Description.ToString()); templateColumn.CellEditingTemplate = CreateEditingTemplate(typeof(ComboBox), itemFilter.Description.ToString()); grdTest.Columns.Add(templateColumn); } Here is the code for creating DataTemplate dynamically. public DataTemplate CreateCellTemplate(Type type, string strBinding) { return (DataTemplate)XamlReader.Load(@"<DataTemplate xmlns=""http://schemas.microsoft.com/client/2007""> <" + type.Name + @" Text=""{Binding " + strBinding + @"}""/> </DataTemplate>"); } public DataTemplate CreateEditingTemplate(Type type, string strBinding) { return (DataTemplate)XamlReader.Load(@"<DataTemplate xmlns=""http://schemas.microsoft.com/client/2007""> <" + type.Name + @" Loaded=""ddlTest_Loaded"" Tag=""{Binding " + strBinding + @"}""/> </DataTemplate>"); } I need to use Loaded="ddlTest_Loaded" in CreateEditingTemplate() ,in order to load the combo box . However it causes exception . When I remove Loaded event it's fine however the combo box is empty. How can I load the combo box when I define it in DataTemplate codebehind.

  • Including partial views when applying the Mode-View-ViewModel design pattern

    - by Filip Ekberg
    Consider that I have an application that just handles Messages and Users I want my Window to have a common Menu and an area where the current View is displayed. I can only work with either Messages or Users so I cannot work simultaniously with both Views. Therefore I have the following Controls MessageView.xaml UserView.xaml Just to make it a bit easier, both the Message Model and the User Model looks like this: Name Description Now, I have the following three ViewModels: MainWindowViewModel UsersViewModel MessagesViewModel The UsersViewModel and the MessagesViewModel both just fetch an ObserverableCollection<T> of its regarding Model which is bound in the corresponding View like this: <DataGrid ItemSource="{Binding ModelCollection}" /> The MainWindowViewModel hooks up two different Commands that have implemented ICommand that looks something like the following: public class ShowMessagesCommand : ICommand { private ViewModelBase ViewModel { get; set; } public ShowMessagesCommand (ViewModelBase viewModel) { ViewModel = viewModel; } public void Execute(object parameter) { var viewModel = new ProductsViewModel(); ViewModel.PartialViewModel = new MessageView { DataContext = viewModel }; } public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; } And there is another one a like it that will show Users. Now this introduced ViewModelBase which only holds the following: public UIElement PartialViewModel { get { return (UIElement)GetValue(PartialViewModelProperty); } set { SetValue(PartialViewModelProperty, value); } } public static readonly DependencyProperty PartialViewModelProperty = DependencyProperty.Register("PartialViewModel", typeof(UIElement), typeof(ViewModelBase), new UIPropertyMetadata(null)); This dependency property is used in the MainWindow.xaml to display the User Control dynamicly like this: <UserControl Content="{Binding PartialViewModel}" /> There are also two buttons on this Window that fires the Commands: ShowMessagesCommand ShowUsersCommand And when these are fired, the UserControl changes because PartialViewModel is a dependency property. I want to know if this is bad practice? Should I not inject the User Control like this? Is there another "better" alternative that corresponds better with the design pattern? Or is this a nice way of including partial views?

    First, fair warning: I am a complete newbie with C# and WPF. I have a combobox (editable, searchable) and I would like to be able to intercept the Delete key and remove the currently highlighted item from the list. The behavior I'm looking for is like that of MS Outlook when entering in email addresses. When you give a few characters, a dropdown list of potential matches is displayed. If you move to one of these (with the arrow keys) and hit Delete, that entry is permanently removed. I want to do that with an entry in the combobox. Here is the XAML (simplified): <ComboBox x:Name="Directory" KeyUp="Directory_KeyUp" IsTextSearchEnabled="True" IsEditable="True" Text="{Binding Path=CurrentDirectory, Mode=TwoWay}" ItemsSource="{Binding Source={x:Static self:Properties.Settings.Default}, Path=DirectoryList, Mode=TwoWay}" / The handler is: private void Directory_KeyUp(object sender, KeyEventArgs e) { ComboBox box = sender as ComboBox; if (box.IsDropDownOpen && (e.Key == Key.Delete)) { TrimCombobox("DirectoryList", box.HighlightedItem); // won't compile! } } When using the debugger, I can see box.HighlightedItem has the value I want but when I try and put in that code, it fails to compile with: System.Windows.Controls.ComboBox' does not contain a definition for 'HighlightedItem'... So: how do I access that value? Keep in mind that the item has not been selected. It is merely highlighted as the mouse hovers over it. Thanks for your help.

  • why can't i bind ipv6 socket to a linklocal address

    - by Haiyuan Zhang
    #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <netdb.h> #include <stdio.h> void error(char *msg) { perror(msg); exit(0); } int main(int argc, char *argv[]) { int sock, length, fromlen, n; struct sockaddr_in6 server; struct sockaddr_in6 from; int portNr = 5555; char buf[1024]; length = sizeof (struct sockaddr_in6); sock=socket(AF_INET6, SOCK_DGRAM, 0); if (sock < 0) error("Opening socket"); bzero((char *)&server, length); server.sin6_family=AF_INET6; server.sin6_addr=in6addr_any; server.sin6_port=htons(portNr); inet_pton( AF_INET6, "fe80::21f:29ff:feed:2f7e", (void *)&server.sin6_addr.s6_addr); //inet_pton( AF_INET6, "::1", (void *)&server.sin6_addr.s6_addr); if (bind(sock,(struct sockaddr *)&server,length)<0) error("binding"); fromlen = sizeof(struct sockaddr_in6); while (1) { n = recvfrom(sock,buf,1024,0,(struct sockaddr *)&from,&fromlen); if (n < 0) error("recvfrom"); write(1,"Received a datagram: ",21); write(1,buf,n); n = sendto(sock,"Got your message\n",17, 0,(struct sockaddr *)&from,fromlen); if (n < 0) error("sendto"); } } when I compile and run the above code I got : binding: Invalid argument and if change to bind the ::1 and leave other thing unchanged in the source code, the code works! so could you tell me what's wrong with my code ? thanks in advance.
