UIElement.PreviewQueryContinueDrag Event

Definition

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

C#
public event System.Windows.QueryContinueDragEventHandler PreviewQueryContinueDrag;

Event Type

Remarks

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

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