- QueryContinueDragEventArgs
A QueryContinueDragEventArgs that contains the event data.
Remarks
After dragging has begun, this method is called repeatedly by the .NET Framework until the drag operation is either canceled or completed.
Note
Override this method if you want to change the point at which dragging is canceled or at which a drop occurs.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnQueryContinueDrag method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnQueryContinueDrag(QueryContinueDragEventArgs) in a derived class, be sure to call the base class's OnQueryContinueDrag(QueryContinueDragEventArgs) method so that registered delegates receive the event.
