Remarks

The HierarchicalDataTemplate enables you to set a data template for the current level of hierarchical data, as well as, set the template for the next sublevel with the ItemTemplate property. Use a HierarchicalDataTemplate to display hierarchical data in a control, such as a TreeView.

Examples

The following example shows two hierarchical data templates declared as resources.

<StackPanel.Resources>
    <sdk:HierarchicalDataTemplate x:Key="ChildTemplate" >
       <TextBlock FontStyle="Italic" Text="{Binding Path=Title}" />
     </sdk:HierarchicalDataTemplate>
    <sdk:HierarchicalDataTemplate x:Key="NameTemplate" 
        ItemsSource="{Binding Path=ChildTopics}" 
        ItemTemplate="{StaticResource ChildTemplate}">
        <TextBlock Text="{Binding Path=Title}" FontWeight="Bold" />
        </sdk:HierarchicalDataTemplate>
</StackPanel.Resources>
