datatemplate

问题 I've got a set of ViewModels that I'm binding to the ItemsSource property of a TabControl. Let's call those ViewModels AViewModel, BViewModel, and CViewModel. Each one of those needs to have a different ItemTemplate (for the header; because they each need to show a different icon) and a different ContentTemplate (because they have very different interaction models). What I'd like is something like this: Defined in Resource.xaml files somewhere: <DataTemplate x:Key="ItemTemplate" DataType="{x

问题 I have 2 Datatemplates. One contain a grid , second one contain a button. I need to send command parameters of button as selected grid items.

问题 The TextBlock resides in a DataTemplate , thus I can't refer to it by its name. So how do I bind its (e.g.) Text property programmatically? XAML: <UserControl x:Class="MyNameSpace.MyCustomControl" ... > ... <ListBox ItemsSource="{Binding Path=ItemsSource}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> ... </UserControl> Code: public partial class MyCustomControl : UserControl { ...

问题 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? 回答1: I would create a non-generic version of BaseViewModel and let the generic one inherit from it: public

问题 I'm try to set the Foreground colour on a Hyperlink using a Style object in an ancestor's Resources , but it's not having any effect. I even used the BasedOn tip from Changing Hyperlink foreground without losing hover color, but it's not made any difference - I still get a blue hyperlink that is red on hover. Here's the XAML for my controls, including an ItemsControl whose items are shown using a hyperlink: <StackPanel Background="Red" TextElement.Foreground="White"> <StackPanel.Resources>

问题 I have a Button in a DataTemplate that is bound to a Command in my ViewModel. The button also has an EventTrigger that kicks off a Storyboard that hides the edit controls (of which the button is a part.) The Storyboard works fine if I pick up the PreviewMouseDown event, but the Command never gets called. If I pick up the MouseDown event in my EventTrigger, the Command works, but the Storyboard doesn't execute. How can I get both the Command and the Storyboard to execute when the button is
