UIElement::QueryContinueDrag Event

.NET Framework (current version)

Occurs when there is a change in the keyboard or mouse button state during a drag-and-drop operation.

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

Syntax

public:
event QueryContinueDragEventHandler^ QueryContinueDrag {
	void add(QueryContinueDragEventHandler^ value);
	void remove(QueryContinueDragEventHandler^ value);
}

Remarks

The QueryContinueDrag event enables the drag source to determine whether the drag-and-drop operation should be canceled.

This event creates an alias for the DragDrop::QueryContinueDrag attached event for this class, so that QueryContinueDrag is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the QueryContinueDrag event are attached to the underlying DragDrop::QueryContinueDrag attached event and receive the same event data instance.
