Examples

This example shows how to apply a DataTemplate for a locally defined Item object. For the code that defines Item and populates the TreeView, see the "Tree view using data binding" example in the TreeView article.

<TreeView Name="DessertTree"
          SelectionMode="Multiple"
          ItemsSource="{x:Bind DataSource}">
    <TreeView.ItemTemplate>
        <DataTemplate x:DataType="local:Item">
            <TreeViewItem ItemsSource="{x:Bind Children}"
                          Content="{x:Bind Name}"/>
        </DataTemplate>
    </TreeView.ItemTemplate>
</TreeView>

Remarks

In Windows 10, version 1803, there is no ItemTemplate property. Instead, you have to re-template the TreeView control and specify a custom ItemTemplate if your content is not a string. This example shows how to apply a DataTemplate to a tree view item in Windows 10, version 1803. For the code that defines Item and populates the TreeView, see the "Tree view using data binding" example in the TreeView article.

<Page.Resources>
    <DataTemplate x:Key="TreeViewItemDataTemplate" x:DataType="local:Item">
        <TreeViewItem ItemsSource="{x:Bind Children}"
                      Content="{x:Bind Name}"/>
    </DataTemplate>

    <Style TargetType="TreeView">
        <Setter Property="IsTabStop" Value="False" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="TreeView">
                    <TreeViewList x:Name="ListControl"
                                  ItemTemplate="{StaticResource TreeViewItemDataTemplate}"
                                  ItemContainerStyle="{StaticResource TreeViewItemStyle}"
                                  CanDragItems="True"
                                  AllowDrop="True"
                                  CanReorderItems="True">
                        <TreeViewList.ItemContainerTransitions>
                            <TransitionCollection>
                                <ContentThemeTransition />
                                <ReorderThemeTransition />
                                <EntranceThemeTransition IsStaggeringEnabled="False" />
                            </TransitionCollection>
                        </TreeViewList.ItemContainerTransitions>
                    </TreeViewList>
