Placing treeview inside a radcombo box which is placed inside repeater

[Amita]

We're developing a user control in which a rad treeview is placed inside a radcombo box.That user control is inside repeater control in  which we add that user control dynamically with add/remove functionality. But it complains when we add usercontrol second time about "Component with same id" and that points to treeview id.

I mean Every treeview behaves as if it had the same id, so if I click on one node to collapse/expand it, the result is that only the treeview's node in the first repeater item collapses or expands.
Is there a way to work out this problem?
