为什么我的嵌套Repeater中的按钮总是要点击两次，才执行事件。

Question

内层中的Repeater中的按钮有时需要点击两次才执行，第一次点击的时候，页面也刷新，产生了回传。但是就是不执行

添加repeater的itemcommand事件，linkbutton去除onclick，设置commandName属性作为判断条件，commandargument作为需要传递的参数。
在itemCommand事件中，这样判断
if(e.CommandName=="select")  //这个设定的commandname="select"
{
  string Id=e.CommandArgument.ToString();  //获取参数
  //你的代码
}

用webform做动态表格嵌套，很头疼。用asp.net mvc就比较好办了。
