datatemplate

问题 I have a View that is basically setup like this: <Grid> <ViewBox> <Grid> <ItemsControl ItemsSource="{Binding MyItems}" ItemTemplate="{Binding Source={StaticResource MyItemsDataTemplate}}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Grid /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </Grid> </ViewBox> </Grid> The DataTemplate used here can be reduced to this: <DataTemplate x:Key="AreaItemDisplayDataTemplate"> <Canvas Grid.ZIndex={Binding Z}> <Grid> // an shape is

问题 The default DataTemplate in a wpf application displays the result of the .ToString() method. I'm developing an application where the default DataTemplate should display nothing. I've tried: <Grid.Resources> <DataTemplate DataType="{x:Type System:Object}"> <Grid></Grid> </DataTemplate> </Grid.Resources> But this doesn't work. Does anyone knows if this is possible without specifiing a specific DataTemplate for every class type in the application? 回答1: I know of no way to do this. As per Joe's

问题 I try to implement a multi column ListView. Everything worked just fine until I tried to style the mouseover- and selection-look of the list view items. I therefore created a ControlTemplate (see XAML below). When I use the ControlTemplate, the DataTemplates for the columns are ignored. When I remove the ControlTemplate everything is fine again.

问题 Edit: Ok after finally playing around numerous times without no luck, I have created a very small Wpf application. You can directly copy this code. Notice when you change values in the TextBox and press the Test button, the values never get updated. I don't understand why the two way binding dosen't work. Please help. Here is the xaml: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <ListView Grid.Row="0" ItemsSource="{Binding

问题 I have a ListBox showing data about employees such as name, department photo, badge number, etc. Employees may have different types such as Manager, Staff, Volunteers. I have 3 separate data templates - one for each type. All of these templates show basically the same data but presented differently. Depending on the user logged into the application pictures, Badge Number, etc, can or cannot be visible. So I have boolean properties for that - CanSeePhotos, CanSeeBadgeNumbers, etc. So if

This is so I
