DragEventHandler

  • The corresponding bubbling event is Drop.

  • Override OnPreviewDrop to implement class handling for this event in derived classes.

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

PreviewDrop is introduced in the .NET Framework version 3.5. For more information, see .NET Framework 3.5 Architecture.

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
