Hi Monika Lather,
Let us suppose that you've added the RadTreeView as a first item of the RadListBox. To be able to find it
use the findControl
function to access the TreeView in the OnClientTransferring event:
tree = sender.get_items().getItem(0).findControl(
is the RadListBox
Please let me know if this was helpful.
