Hi,
I need to retrieve some information about a target node while dragging. This is needed to give the user an optical feedback if he is allowed to drop the node he currently is dragging onto the node he currently is over.
For that I need to retrieve the supposed target node and compare several attributes against the source node to determine if the operation is valid or not.
Waiting until the user actually dropped the node and cancelling the OnClientNodeDropping event is NOT an option. The user must be able to see if the desired operation is valid or not BEFORE dropping.
So how can I retrieve the supposed target node in the OnClientNodeDragging event?
Thanks,
Sebastian
