ContentElement::PreviewDragEnter 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^ PreviewDragEnter {
	void add(DragEventHandler^ value);
	void remove(DragEventHandler^ value);
}

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