ContentElement.DragEnter Event


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

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

public event DragEventHandler DragEnter

This event creates an alias for the DragDrop.DragEnter attached event for this class, so that ContentElement.DragEnter is part of the class members list when ContentElement 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.
