UIElement3D.DragEnter UIElement3D.DragEnter UIElement3D.DragEnter UIElement3D.DragEnter Event


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

 event System::Windows::DragEventHandler ^ DragEnter;
public event System.Windows.DragEventHandler DragEnter;
member this.DragEnter : System.Windows.DragEventHandler 
Public Custom Event DragEnter As DragEventHandler 


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

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