Occurs when a drag-and-drop operation is completed.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Point clientPoint = targetControl.PointToClient(new Point(de.X, de.Y));
In versions earlier than .NET Framework 2.0, if you put a UserControl with DragEnter and events on a Windows Form and drag and drop something onto the UserControl at design time, the DropDrop and DropEnter events are raised. However, when you close and reopen the solution, the DragEnter and events are not raised again.
For more information about handling events, see Handling and Raising Events.
