UIElement3D.PreviewQueryContinueDrag Event


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)

member PreviewQueryContinueDrag : IEvent<QueryContinueDragEventHandler,

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  for this class, so that PreviewQueryContinueDrag is part of the class members list when UIElement3D 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. GTMT

PreviewQueryContinueDrag is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
