備註

從中移除子控制項時, OnControlRemoved會呼叫ToolStripThe OnControlRemoved is called when a child control is removed from the ToolStrip.

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊, 請參閱處理和引發事件For more information, see Handling and Raising Events.

OnControlRemoved 方法也允許衍生類別處理事件,而不用附加委派。The OnControlRemoved method also allows derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

當在衍生類別中覆寫 OnControlRemoved(ControlEventArgs) 時,請確定呼叫基底類別的 OnControlRemoved(ControlEventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnControlRemoved(ControlEventArgs) in a derived class, be sure to call the base class's OnControlRemoved(ControlEventArgs) method so that registered delegates receive the event.
