Examples

This example shows how to find elements that are generated by a DataTemplate.

In this example, there is a ListBox that is bound to some XML data:

XAML

<ListBox Name="myListBox" ItemTemplate="{StaticResource myDataTemplate}"
         IsSynchronizedWithCurrentItem="True">
  <ListBox.ItemsSource>
    <Binding Source="{StaticResource InventoryData}" XPath="Books/Book"/>
  </ListBox.ItemsSource>
</ListBox>

The ListBox uses the following DataTemplate:

XAML

<DataTemplate x:Key="myDataTemplate">
  <TextBlock Name="textBlock" FontSize="14" Foreground="Blue">
    <TextBlock.Text>
      <Binding XPath="Title"/>
    </TextBlock.Text>
  </TextBlock>
</DataTemplate>

If you want to retrieve the TextBlock element generated by the DataTemplate of a certain ListBoxItem, you need to get the ListBoxItem, find the ContentPresenter within that ListBoxItem, and then call FindName on the DataTemplate that is set on that ContentPresenter. The following example shows how to perform those steps. For demonstration purposes, this example creates a message box that shows the text content of the DataTemplate-generated text block.
