UIElement3D.PreviewDragOver Event

.NET Framework (current version)
 

Occurs when the input system reports an underlying drag event with this element as the potential drop target.

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

public event DragEventHandler PreviewDragOver

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

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