Hide RadTreeViewContextMenu - RadMenuItem

[mike]

I have built a treeview with 2 levels.
Level 2 has a RadTreeViewContextMenu with several RadMenuItem's - Add, edit, delete copy etc...
The delete RadMenuItem must be hidden if there is only 1 node at level 2 within the parent.

I am easily able to hide a RadTreeViewContextMenu - RadMenuItem with the following syntax:

 

 

treeview.ContextMenus[i].Items[i].Visible = false;}

but this will hide the delete RadMenuItem for ALL nodes at level 2 in all level 1 nodes.

Is it possible to hide a RadMenuItem within a group of nodes?

eg ..........
Parent A
    child 1 // display delete RadMenuItem
    child 2 // display delete RadMenuItem
    child 3 // display delete RadMenuItem
Parent B
    child 1 // HIDE the delete RadMenuItem
