UIElement.DragOver 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)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public event DragEventHandler DragOver
/** @event */
public void add_DragOver (DragEventHandler value)

/** @event */
public void remove_DragOver (DragEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
<object DragOver="DragEventHandler" .../>

DragEventHandler

  • The corresponding tunneling event is PreviewDragOver.

  • Override OnDragOver to implement class handling for this event in derived classes.

This event occurs even if the drag originates in the element bounds. If the drag starts outside the bounds and then moves inside, this event is also raised, as well as DragEnter and related preview events.

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