    When you Drag and drop an item onto itself it is creating a duplicate item in the listbox.  Is this expected behavior and if so is there a way to prevent it from creating the duplicate item.


    We don't handle the ghost entry so it isn't a real problem just visually its been annoying our users.

    Hello Frank,

    Unfortunately, I'm unable to reproduce the behavior you've described in a sample project, nor can I reproduce it in the demos available in the Silverlight Controls Samples or SDK Samples Browser.

    I'm attaching a sample project where I've set up a RadListBox with a DragDropBehavior set to the default implementation of the ListBoxDragDropBehavior class as demonstrated in the Drag & Drop Overview article. Could you please try reproducing the issue in this sample project and let me know what modifications I should make?

    If you're unable to do so, could you please provide more information on the setup you have at your end or, ideally, provide a sample project which demonstrates the issue, so that I may better assist you in finding a solution?

    Thank you in advance for your cooperation on the matter. I will be awaiting your reply.

    This can be disregarded.  We are using System.windows.control.listbox.  And using RadDragandDropmanager to handle the drag drop operations in the viewmodel.
