Thanks for the reply.
In Treeview, there is a property called "dropPosition" which i can set in drop / dragend event.
In TreeList, there is a property called "position" which i can set in drop / dragend event. It is not having any impact on setting the position property to value "before" / "after".
Can you please help me with a code snippet on how i can achieve the same in tree list?
Thanks in advance!
