OnRowDirtyStateNeeded 方法还允许派生类对事件进行处理而不必附加委托。The OnRowDirtyStateNeeded method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

在派生类中重写 OnRowDirtyStateNeeded(QuestionEventArgs) 时,一定要调用基类的 OnRowDirtyStateNeeded(QuestionEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnRowDirtyStateNeeded(QuestionEventArgs) in a derived class, be sure to call the base class's OnRowDirtyStateNeeded(QuestionEventArgs) method so that registered delegates receive the event.
