I've seen the samples here for canceling a Drag and Drop event across different object using the Manager but I simply need the following.
I have a treeView and the user can drag and drop nodes within the same treeView only.
I want to prompt the user "Do you want to do this?".
if dialogResult==OK then do it else set Handled=false.
Problem is that the prompt for the messagebox is asych and the previewDrag completes and calls the Drag before the response to the messagebox result is called.
How can I prompt the user during a drag and drop and cancel if needed? Can it be done without the DragAndDrop manager and use the TreeView properties and events?
