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?
