OnRowHeightInfoNeeded 方法还允许派生类对事件进行处理而不必附加委托。The OnRowHeightInfoNeeded 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 OnRowHeightInfoNeeded(DataGridViewRowHeightInfoNeededEventArgs) 时,请确保调用基类 "OnRowHeightInfoNeeded(DataGridViewRowHeightInfoNeededEventArgs) 方法,以便注册的委托接收事件。When overriding OnRowHeightInfoNeeded(DataGridViewRowHeightInfoNeededEventArgs) in a derived class, be sure to call the base class' OnRowHeightInfoNeeded(DataGridViewRowHeightInfoNeededEventArgs) method so that registered delegates receive the event.
