備註

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.

OnPaddingChanged 方法也允許衍生類別處理事件，而不用附加委派。The OnPaddingChanged 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

OnPaddingChanged(EventArgs)在衍生類別中覆寫時，請務必呼叫基類的方法， OnPaddingChanged(EventArgs) 以便註冊的委派會接收事件。When overriding OnPaddingChanged(EventArgs) in a derived class, be sure to call the base class' OnPaddingChanged(EventArgs) method so that registered delegates receive the event.
