Hi,

You could take a look at the following article as a start: http://www.telerik.com/help/silverlight/radtreeview-populating-with-data-hierarchical-data-templates.html 

You could use ItemTemplate property of the HierarchicalDataTemplate element to provide data template (or hierarchical template) for the children of the element.

<DataTemplate x:Key="ThirdLevelTemplate">
    <TextBlock Text="{Binding Name}" />
</DataTemplate>
 
<telerik:HierarchicalDataTemplate x:Key="SecondLevelTemplate"
        ItemsSource="{Binding Items}"
        ItemTemplate="{StaticResource ThirdLevelTemplate}">
    <TextBlock Text="{Binding Name}" />
</telerik:HierarchicalDataTemplate>
 
<telerik:HierarchicalDataTemplate x:Key="FirstLevelTemplate"
        ItemsSource="{Binding Items}"
        ItemTemplate="{StaticResource SecondLevelTemplate}">
    <TextBlock Text="{Binding Name}" />
</telerik:HierarchicalDataTemplate>

You could also take a look at our online demos for inside and samples: http://demos.telerik.com/silverlight/#TreeView/FirstLook.

Hope this helps, please let us know if you need further assistance.
