                if (e.CommandName == "AuditDelay")
                {                   ModalPopupDelay.Show();
                }
          }
}
执行时ModalPopupDelay.Show();代码有效，但是不弹出窗口，但是把ModalPopupDelay放到UpdatePanel 里面就可以弹出，但是刷新页面。
但是我别的页面不需要把ModalPopupDelay放到UpdatePanel 里面就可以弹出，这是怎么回事呢？

Answer 1

虽然问题解决了，但是我还是不知道原因，为什么放在ModalPopupDelay放到UpdatePanel 里面就可以弹出，但是刷新页面。？？

Answer 2

刷新页面是要在web.config里加些东西。  <compilation debug="true">
