HtmlAnchor.OnServerClick(EventArgs) 方法

  • 參考

定義

命名空間:
System.Web.UI.HtmlControls
組件:
System.Web.dll

引發 ServerClick 事件。 這個方法可讓您提供該事件的自訂處理常式。

protected:
 virtual void OnServerClick(EventArgs ^ e);
protected virtual void OnServerClick (EventArgs e);
abstract member OnServerClick : EventArgs -> unit
override this.OnServerClick : EventArgs -> unit
Protected Overridable Sub OnServerClick (e As EventArgs)

參數

e
EventArgs

包含事件資料的 EventArgs。

範例

下列程式碼範例示範如何以宣告方式指定和撰寫 ServerClick 事件的事件處理常式程式碼。 HtmlAnchor按一下控制項時，會顯示訊息。

備註

ServerClick按一下控制項時 HtmlAnchor ，就會引發 事件。 此伺服器事件會導致從用戶端到伺服器和返回的來回行程。

引發事件會透過委派叫用此事件處理常式。 如需詳細資訊，請參閱 處理和引發事件。

OnServerClick 方法也允許衍生類別處理事件，而不用附加委派。 這是在衍生類別中處理事件的慣用技巧。

給繼承者的注意事項

當在衍生類別中覆寫 OnServerClick(EventArgs) 時，請確定呼叫基底類別的 OnServerClick(EventArgs) 方法，使已註冊的委派能接收到事件。
