範例
以下程式碼範例示範如何宣告式指定並編寫事件處理程序。ServerClick 點擊控制鍵時 HtmlAnchor ，會顯示訊息。

備註
當按下控制鍵時ServerClick，事件HtmlAnchor會被觸發。 此伺服器事件會造成客戶端與伺服器之間的往返。
發起事件會透過代理呼叫事件處理者。 欲了解更多資訊，請參閱 處理與提升事件。
此 OnServerClick 方法也允許衍生類別在不附加代理的情況下處理事件。 這是在衍生類別中處理事件的首選技術。
給繼承者的注意事項
在導出類別中覆寫 OnServerClick(EventArgs) 時，務必呼叫基底類別的方法 OnServerClick(EventArgs) ，讓註冊代理接收事件。
