后台代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Timer
{
    public partial class index : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Label2.Text = "页创建在" + DateTime.Now.ToLongTimeString();
        }
        protected void Timer1_Tick(object sender, EventArgs e)
        {
            Label1.Text = "刷新在" + DateTime.Now.ToLongTimeString();
        }
    }
}
搭建在服务器IIS上，在服务器本地浏览时候能刷新时间, 而到客户端浏览时就不刷新时间了？  请求高人帮忙解决

------解决方案--------------------
当然，服务器端使用Timer刷新界面是无效的。因为这些更新根本不会传送到客户端去。

你得使用js的timer。
------解决方案--------------------
既然页面这么简单，那么贴出从你的“客户端”浏览器上得到的html源代码来！

AJAX提供Timer控件实现时间计时提示功能
//每隔一秒触发一次Timer1_Tick事件
protected void Timer1_Tick(object sender, EventArgs e)
    {
        this.Label1.Text = System.DateTime.Now.ToString();
        SqlDataReader sdr1 = this.ExceRead("select * from tb_memo ");
        while (sdr1.Read())
        {
            this.Label2.Text = sdr1["alerttime"].ToString();
            if (this.Label1.Text == sdr1["alerttime"].ToString())
            {
                this.Label2.Text = sdr1["subject"].ToString();
                ScriptManager.RegisterClientScriptBlock(UpdatePanel1, this.GetType(), "", "var MSG1 = new PopBubble('短消息提示：','" + this.Label2.Text + "'); MSG1.show();", true);
            }
        }
        sdr1.Close();
}
//显示系统时间
protected void Page_Load(object sender, EventArgs e)
    {
        string date;
        date = System.DateTime.Now.ToShortDateString() + " " + this.ddlhour.SelectedItem.Text + ":" + this.TxtMinute.Text + ":" + this.TxtSecond.Text;
        this.Label2.Text = date;
    }
//添加相关数据到数据库
protected void ImgQueDing_Click(object sender, ImageClickEventArgs e)
    {
        if (this.TxtSubject.Text.Length > 20)
