Command.Click 事件
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
在使用者啟動 Command 控制項時發生。 這個 API 已經過時。 如需如何開發 ASP.NET 行動應用程式的資訊，請參閱 具有 ASP.NET 的Mobile Apps & Sites。
public:
event EventHandler ^ Click;public event EventHandler Click;member this.Click : EventHandler Public Custom Event Click As EventHandler 事件類型
範例
下列程式代碼範例示範如何附加命令事件。 按兩下任一 Command 按鈕會 OnItemCommand 引發事件。 用戶定義函式會使用 CommandEventArgs 自變數來查看按下的 Command 按鈕。
注意
下列程式代碼範例使用單一檔案程序代碼模型，如果直接複製到程序代碼後置檔案，可能無法正確運作。 此程式代碼範例必須複製到擴展名為 .aspx 的空白文本檔。 如需 Web Forms 程式代碼模型的詳細資訊，請參閱 ASP.NET 網頁代碼模型。

Command啟用控件時，它會引發 OnClick 事件。 如需詳細資訊，請參閱 中的和一 System.Web.UI.MobileControls.Command節。
