Remarks
DragEventHandler is the delegate you implement to handle these events:
These events are routed events. Changing the value of the Handled property of DragEventArgs from an event handler can influence how a routed event behaves. For more info on the routed event concept, see Events and routed events overview.
The Control class has pre-wired event handlers that Control derived types can override to provide class-based handling for the drag-drop events,. These methods are:
The Windows Runtime implementation of drag-drop concepts permits only certain controls and input actions to initiate a drag-drop action. There is no generalized DoDragDrop method that would permit any UI element to initiate a drag-drop action. The main source of a drag-drop action is when you drag the items of a list such as GridView.
