Hello Jon,

You can define a different DataTemplate for each level of the tree - thus declaring different templates for the separate types of data items. Then you can define a ContextMenu only in the Products and Categories DataTemplates. For example the Products DataTemplate can be defines as:

<telerik:HierarchicalDataTemplate x:Key="ProductsTemplate" >

<TextBlock Text="{Binding Name}">

<telerikNavigation:RadContextMenu.ContextMenu>

<telerikNavigation:RadContextMenu Opened="RadContextMenu_Opened">

<telerikNavigation:RadMenuItem Header="Item1" />

<telerikNavigation:RadMenuItem Header="Item2" />

</telerikNavigation:RadContextMenu>

</telerikNavigation:RadContextMenu.ContextMenu>

</TextBlock>

</telerik:HierarchicalDataTemplate>

Give this approach a try and let me know if it works for you.

However, if your scenario requires a different approach or you need more info, please let us know.

Hi Jon,

Since you generate the RadTreeViewItems in the code-behind, you can check if you are about to create "branch 3 or 4" item just attach a ContextMenu to it.

RadTreeViewItem newItem = new RadTreeViewItem();

//initialize it here.

//Check if the newItem should have ContextMenu?

//Then

RadContextMenu menu = new RadContextMenu();

//add MenuItems here

RadContextMenu.SetContextMenu(newItem , menu);

If you have further questions, please ask us.
