Hi Randy,
Thanks for your update.
Query 1:”When an item is dragged from the listbox on the right: if the listbox item is dropped on the listbox, nothing should happen. If the listbox item is dropped on a treeview node, then some action will be taken.”
We have now modified the sample and if the listbox item is dropped on listbox nothing will be happen. Please find the modified Demo link below.
Query 2:”In the listbox itemDrop event is there a way to distinguish between these two targets?”
Yes, we can distinguish between the targets with using target in the listbox itemDrop argument. This args.target will give us the current target class, so that we can differentiate based on the target object.
Please let us know if you have any queries further.
Regards,
Arun P.
