我正在创建一个动态Web应用程序.控件是完全从背后的代码创建的.对于页面中的几个按钮，我想回发，因此我将它们动态地添加到了updatepanel中.但是当我单击按钮时，整个页面都会回发，并且click事件似乎从未触发过. 以下是我使用的代码.请让我知道我做错了吗?

Hi, I am creating a dynamic web application.The controls are completely created from code behind.For few buttons in my page i want post back, so i added them to updatepanel dynamically.But when i click the button the entire page post backs and also the click event never seems to be firing. Below is the Code i used.please let me know what i am doing wrong?

protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { DrawBoxes(); } } public void DrawBoxes() { for (int i = 0; i < 10; i++) { TextBox txtBx = new TextBox(); txtBx.ID = i.ToString(); this.Form.Controls.Add(txtBx); } for (int i = 0; i < 10; i++) { Button bt = new Button(); bt.ID = "dymBtn" + i; bt.Text = "Click Me"; bt.Click += new EventHandler(ClickDel); UpdatePanel updPanel = new UpdatePanel(); updPanel.ID = "upd" + i; updPanel.UpdateMode = UpdatePanelUpdateMode.Conditional; updPanel.ContentTemplateContainer.Controls.Add(bt); Page.Form.Controls.Add(updPanel); } } protected void ClickDel(object sender, EventArgs e) { Button objbtn = (Button)sender; HttpContext.Current.Response.Write(objbtn.Text + "Hellllo"); }
