参数

注解

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息, 请参阅处理和引发事件For more information, see Handling and Raising Events.

OnRenderToolStripPanelBackground 方法还允许派生类对事件进行处理而不必附加委托。The OnRenderToolStripPanelBackground 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 OnRenderToolStripPanelBackground(ToolStripPanelRenderEventArgs) 时,一定要调用基类的 OnRenderToolStripPanelBackground(ToolStripPanelRenderEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnRenderToolStripPanelBackground(ToolStripPanelRenderEventArgs) in a derived class, be sure to call the base class's OnRenderToolStripPanelBackground(ToolStripPanelRenderEventArgs) method so that registered delegates receive the event.
