Control.OnQueryContinueDrag Method

Raises the QueryContinueDrag event.

[Visual Basic]
Protected Overridable Sub OnQueryContinueDrag( _
   ByVal qcdevent As QueryContinueDragEventArgs _
protected virtual void OnQueryContinueDrag(
 QueryContinueDragEventArgs qcdevent
protected: virtual void OnQueryContinueDrag(
 QueryContinueDragEventArgs* qcdevent
protected function OnQueryContinueDrag(
   qcdevent : QueryContinueDragEventArgs


A QueryContinueDragEventArgs that contains the event data.


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 Raising an Event.

The OnQueryContinueDrag method also allows 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 in a derived class, be sure to call the base class's OnQueryContinueDrag method so that registered delegates receive the event.
