ContentElement::PreviewDragOver Event

 

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 {
	void add(DragEventHandler^ value);
	void remove(DragEventHandler^ value);
}

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 ContentElement 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.
