FrameworkContentElement.ContextMenuOpening Event

Occurs when any context menu on the element is opened.

Namespace: System.Windows
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public event ContextMenuEventHandler ContextMenuOpening
/** @event */
public void add_ContextMenuOpening (ContextMenuEventHandler value)

/** @event */
public void remove_ContextMenuOpening (ContextMenuEventHandler value)

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

Delegate

ContextMenuEventHandler

To manually open context menus, handlers of the events should mark the relevant event as handled. Otherwise, the value of the ContextMenu property will be used to automatically open a context menu. Marking the event handled will effectively cancel the default action, and could be an opportunity to reset the value of the ContextMenu property and then open the new ContextMenu.

To use this event as an EventTrigger in a style, you must reference the underlying service event identifier:

<EventTrigger RoutedEvent="ContextMenuService.ContextMenuOpening">
  <!-- storyboard here ... -->
</EventTrigger>

(This usage is required because the event implementation on FrameworkContentElement that exposes the underlying service event does not correctly map the ContextMenuOpening identifier for use in triggers).
