Question:
I have the following XML being set on my treeview:
<Root Value="YES"> <Child Name="Test"> <Sibling Data="Yes"> <Last UserData="1"/> </Sibling> <Sibling Data="No"/> </Child> <Child Name="Test2"/> </Root> and then I have set the following code in my window:
<Window.Resources> <XmlDataProvider x:Key="dataProvider" XPath="Root" Source="C:\XML.xml" /> <HierarchicalDataTemplate DataType="Root" ItemsSource="{Binding XPath=*}"> <TextBlock Text="{Binding XPath=@Value}" /> <HierarchicalDataTemplate.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Border Background="Blue"> <ContentPresenter/> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </HierarchicalDataTemplate.ItemContainerStyle> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="Child" ItemsSource="{Binding XPath=*}"> <TextBlock Text="{Binding XPath=@Name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="Sibling" ItemsSource="{Binding XPath=*}"> <TextBlock Text="{Binding XPath=@Data}" /> </HierarchicalDataTemplate> </Window.Resources> <Grid> <TreeView Margin="12" x:Name="trv" ItemsSource="{Binding Source={StaticResource dataProvider}}" /> </Grid> I would like to have a border control wrap around all the subitems for every node as in this image:

In other words, you'll notice in the image I've linked to, the parent node dialogik.Memory has a dark gray border that goes around it and around its children. That's the effect I want to achieve.
What do I need to change in my code to have it work correctly ???
Thanks !!
Solution:1
That's not possible with the TreeView. You could use an Expander though, see here:
http://msdn.microsoft.com/en-us/library/system.windows.controls.expander.aspx
..and then bind it similarly: you'd have an ItemsControl that outputs an Expander for each item, and the Expander would then contain another ItemsControl for child items, recursively.
Hope that helps!
