    }
现在的问题是：当我点击linkbutton按钮后不能翻页。我调试了下，点击linkbutton后不会触发public void PagerButtonClick(object sender, EventArgs e)这个事件，不知道是为什么？请知道的朋友帮我解答下，在线等，先谢谢了

Answer 1

你的linkbutton好像没有事件吧？

Answer 2

我现在不知道linkbutton里的事件怎么跟void PagerButtonClick(object sender, EventArgs e)联系起来

Answer 3

你的 PagerButtonClick 是什么方法？
你可以用linkbutton的onclick方法，在onclick方法里调用PagerButtonClick
