Control.OnQueryContinueDrag(QueryContinueDragEventArgs) Method

Definition

Raises the QueryContinueDrag event.

protected:
 virtual void OnQueryContinueDrag(System::Windows::Forms::QueryContinueDragEventArgs ^ qcdevent);
protected virtual void OnQueryContinueDrag (System.Windows.Forms.QueryContinueDragEventArgs qcdevent);
abstract member OnQueryContinueDrag : System.Windows.Forms.QueryContinueDragEventArgs -> unit
override this.OnQueryContinueDrag : System.Windows.Forms.QueryContinueDragEventArgs -> unit
Protected Overridable Sub OnQueryContinueDrag (qcdevent As QueryContinueDragEventArgs)

Parameters

qcdevent
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.
