次の例では、名前付き領域の上にカーソルを変更するハンドラーを実装するDisplayArea(示されていません)。The following example implements a handler that changes the cursor over a named region DisplayArea (not shown). コメントのヒントに、UIElement使用状況、実際にこのサンプルは同じですが、場合DisplayAreaされた、FrameworkContentElementします。The comment hints at a UIElement usage, but in fact this sample would be identical if DisplayArea were a FrameworkContentElement.

注釈

閉じないようにするには、イベントのハンドラーのコンテキスト メニュー、する必要があります、処理済みとしてマークします。To suppress closing context menus, handlers of the event should mark it as handled.

としては、このイベントを使用して、EventTriggerスタイルでは、基になるサービスのイベント識別子を参照する必要があります。To use this event as an EventTrigger in a style, you must reference the underlying service event identifier:

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

(この使用法が必要なのでイベントの実装FrameworkContentElementこと公開基になるサービスのイベントが正しくマップされない、ContextMenuClosingトリガーで使用するための識別子)。(This usage is required because the event implementation on FrameworkContentElement that exposes the underlying service event does not correctly map the ContextMenuClosing identifier for use in triggers).
