Hello all,
Is it possible to dynamically show the user whether a d&d operation on the tree is allowed?
I would like that whenever the user drags over an item in the treeview that a function is called which evaluates whether a drop is possible there.
Of course the d&d indicator should change colour or otherwise indicate that the d&d operation is possible or not.
That should happen while the user is dragging and not when he is letting go of the item. Otherwise its frustrating as the user will have to find out by trial and error where a drop is allowed.
Thanks in advance.
