If I’m ‘Drop’ing a TreeView node onto another Node. At the end of a Drag/Drop operation, I want to prompt the user to ‘Confirm’ the Drop, and then cancel/undo the Drop if they cancel.

This confirmation is currently in the Drop operation event , ie by opening a child window. However by the time the user confirms one way or the other, the event will already have finished and so I don’t have an opportunity to ‘Cancel’ in the normal way? ie…

itemDragArgs.Cancel = true;
itemDragArgs.Handled = true;

Has anyone had any experience with such a scenario?

    We have a similar scenario with some other controls in which,

    • The dropped Node is ignored (cancelled & handled = true) but keep the reference of the node (in an object field or smth)
    • upon confirmation, add the object to the node.

    Something like this would be of any help?
