推荐答案

您必须在每个回发中创建LinkBut​​ton.如果Page中不存在该事件，则无法触发该事件.

You must create the LinkButton on every postback. If it doesn''t exist in the Page, the event cannot fire.

您可能需要添加以下内容:

You might need to add the following:

lbl = new LinkButton();
lbl.Text = "hai";
lbl.ID = "ll";

//this line
lbl.AutoPostBack = true;

pnl.Controls.Add(lbl);
lbl.Click +=new EventHandler(lbl_Click);
