Drag and Drop with WPF ListBox

问题

I have two ListBox in WPF application. One is the source second is the destination. I took the help from the article http://dotnetslackers.com/ADO_NET/re-191632_Generic_WPF_Drag_and_Drop_Adorner.aspx

Now I have managed to perform the drag and drop.

Now I have one feature to implement in which if we drop any item over an existing one, it will replace the existing item with the current dragged item.

Please guide.

You may want to look at Gong Solutions Drag/Drop for WPF, the guide it uses an adorner and should be able to show you how to remove the old item and add a new one, as @kenny suggested.
