UIElement3D.PreviewDragLeave Event

 

Occurs when the input system reports an underlying drag event with this element as the drag origin.

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

member PreviewDragLeave : IEvent<DragEventHandler,
    DragEventArgs>

This event creates an alias for the DragDrop.PreviewDragLeave attached event for this class, so that PreviewDragLeave is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the PreviewDragLeave event are attached to the underlying DragDrop.PreviewDragLeave attached event and receive the same event data instance.

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