public void DoDragDrop( 
   UIElement source,
   MouseEventArgs e,
   DragDropEffect effect
)

Parameters

source

System.Windows.UIElement that will be dragged.

e

System.Windows.Input.MouseEventArgs that contains the mouse position when the drag operation starts.

effect

DragDropEffect supported by the operation.

The e is not strictly required, but is usually available since drag drop operations are initiated by mouse actions. If you don't have a System.Windows.Input.MouseEventArgs to provide, pass null instead.

The method causes the drag operation to start, then returns immediately. The caller is responsible for monitoring and completing the operation using the DragStart, DragEnter, DragOver, and DragDrop events.
