Control.OnQueryContinueDrag Method (QueryContinueDragEventArgs)

 

Raises the QueryContinueDrag event.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected virtual void OnQueryContinueDrag(
	QueryContinueDragEventArgs qcdevent
)

Parameters

qcdevent
Type: System.Windows.Forms.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.

System_CAPS_noteNote

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