Context Menu - How to limit 'opening' only certain nodes

[Jon]

Hi..
I have treeview with  4 branches  (will never have more)

ROOT
   -- CUSTOMERS
       --  PRODUCTs
            ----  CATEGORY

I only want to enable the context menu if they select PRODUCTS or CATEGORY.

Any ideas ? thanks again....

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..
The treeview is programmatically generated.
How can I determine the branch?  I only want the context menu on branch 3 and 4

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.
