    I build a list as itemsource for treeview.  i am able to see the child items but not able to see the  header of the Parent elements.
    Here posting my code:

    page.xaml:
    --------------

    <
    telerikNavigation:RadTreeView x:Name="radTreeView" Grid.Row="1" >

     

     

     

    <telerikNavigation:RadTreeView.ItemTemplate>

     

     

     

    <core:HierarchicalDataTemplate x:Name="datatemplate" ItemsSource="{Binding DataPoints}">

     

     

     

    <TextBlock Text="{Binding DisplayName}"/>

     

     

     

    </core:HierarchicalDataTemplate>

     

     

     

    </telerikNavigation:RadTreeView.ItemTemplate>

     

     

     

    </telerikNavigation:RadTreeView>

    page.xaml.cs:
    ------------------------
    radtreeview.itemsSource=data; //include the child list object(DataPoints) in this  object

    Hi naga,

    If you are not able to see the headers of your parent elements this must be caused by binding to an incorrect value in your HierarchicalDataTemplate. From the code snippet you posted I see that you are binding the TextBox element that is going to be rendered as the header of the parent treeview items is bound to a property called "DisplayName". Does this property exist?
