datatemplate

I need to set change background color for list item when mouse is over. Here is my code: <DataTemplate x:Key="ListBoxSubCategoryListTemplate" DataType="{x:Type ListBoxItem}"> <StackPanel> <Button x:Name="btnSubCategoryList" Template="{StaticResource subCategoryListItems}" Content="{Binding Path=sub_category_name}" Background="Transparent" Height="25"/> </StackPanel> </DataTemplate> <ControlTemplate x:Key="subCategoryListItems" TargetType="{x:Type Button}"> <StackPanel FlowDirection="LeftToRight" Orientation="Horizontal" > <TextBlock Width="150" Height="{TemplateBinding Button.Height}" x:Name=

The following xaml works ok inside a Window : <Border Width="45" Height="55" CornerRadius="10" > <Border.Background> <ImageBrush> <ImageBrush.ImageSource> <CroppedBitmap Source="profile.jpg" SourceRect="0 0 45 55"/> </ImageBrush.ImageSource> </ImageBrush> </Border.Background> </Border> But when I use the equivalent code in a DataTemplate I get the following error in run-time: Failed object initialization (ISupportInitialize.EndInit). 'Source' property is not set. Error at object 'System.Windows.Media.Imaging.CroppedBitmap' in markup file. Inner Exception: {"'Source' property is not set."} The

I have a generic class public abstract class BaseViewModel<T> Since I am trying to create a DataTemplate that will be applied to all classes that derive from BaseViewModel, I set the type to BaseViewModel: <DataTemplate DataType="{x:Type vm:BaseViewModel}"> However, this does not work since it looks like xaml does not support generic data types. Are there any work arounds to this? I would create a non-generic version of BaseViewModel and let the generic one inherit from it: public abstract class BaseViewModel { // members that are not T-specific, if any // (not required, but could prove useful

Is this possible? I have a ListView and I want to create a template for the columns, so that each column that I mark as a 'cellTextBox' displays with a textbox in it (and also calls the TextBox_LostFocus() on the LostFocus event). I'd really like to use a single template rather than defining a DockPanel and TextBox for every single column. However, each column is going to be bound to a different column in the data source. In other words, I'd like a "cookie cutter" for GridViewColumns that allows me to specify a different binding path for each one. I tried something like this (among other

Possible Duplicate: How to make ListBox editable when bound to a List<string>? I'm trying to set a two-binding between a List named "ListStr" object and a ListBox WPF control. Besides I want the items to be editable, so I added a DataTemplate with TextBoxes expecting that it would modify the ListStr items straight away via TextBoxes. But when I'm attempting to edit one of them, it doesn't work... Any Idea ? PS: I've tried to add the Mode=TwoWay parameter, but it's still not working Here is the XAML : <ListBox ItemsSource="{Binding Path=ListStr}" Style="{DynamicResource ResourceKey

I've been googling this for the last 2 days and cant get anywhere, I just cant do anything to any control in a datatemplate of a tabcontrol. First off, the code: private void Window_Loaded(object sender, RoutedEventArgs e) { tabControl1.ItemsSource = new string[] { "TabA", "TabB", "TabC" }; } private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e) { ContentPresenter cp = tabControl1.Template.FindName("PART_SelectedContentHost", tabControl1) as ContentPresenter; DataTemplate dt = tabControl1.ContentTemplate; Grid g = tabControl1.ContentTemplate.FindName("myGrid",

This morning I asked a question here and doing a simple working sample gave me a different behavior than expected. Full working sample at GitHub . Main partial code below. In this present case, the command is never propagated to any UserControl, either if the UserControl is use directly as a child of the Window. It also not work if the UserControl is used as a DataTemplate for a ListBox ItemTemplate. I also include a hack button to fix the problem where the Command reach the UserControls. The hack come from StackOverflow . But using the hack does not explain why UserControl does not receive
