I have a radtreeview where I can drag and drop nodes and reorder them. Everything is working but what I'd like to do is add a RadConfirm or RadWindow message after a node is dropped that asks for confirmation before the node is dropped. I can't seem to figure out how this can be done. In my OnClientNodeDropping, I am opening a radwindow, but because the RadWindow works asynchronously, my ClientNodeDropping function is exiting before I get a response from the radwindow. Any kind of example on how to do this would be appreciated!
