在updatePanel外动态添加一些按钮，然后添加到tiger中，点击外部按钮的时候，点第一个正常，点第二个就刷新了整个页面，求赐教！！！
代码如下：后台

C# code

 /// <summary>        /// 绑定列头        /// </summary>        private void Initial()        {            AggregateAnalyse.BLL.EM_B_MT dal = new AggregateAnalyse.BLL.EM_B_MT();            DataTable dt = dal.GetBrName("84");            if (dt == null || dt.Rows.Count < 1)            { return; }            int index = 1;            int len = dt.Rows.Count;            foreach (DataRow dr in dt.Rows)            {                HtmlGenericControl div = new HtmlGenericControl("div");                div.ID = "mx" + index.ToString();                if (index == 1)                {                    div.Attributes.Add("class", "menu_true");                    this.hidFirstBrCode.Value = dr[0].ToString();                }                else                {                    div.Attributes.Add("class", "menu_false");                }                div.Attributes.Add("onclick", string.Format("SwitchAnything('mx','cx','menu_true','menu_false',{0},1,{1});", index, len));                LinkButton btn = new LinkButton();                btn.ID = "btnMtCode" + index.ToString();                btn.Text = dr[1].ToString();                btn.CssClass = "btnMenu";                btn.Attributes.Add("Font-Underline", "false");                btn.CommandName = dr[0].ToString();                btn.Click += new EventHandler(this.BtnBrCode_Click);                div.Controls.Add(btn);                divMenu.Controls.Add(div);                AsyncPostBackTrigger triger = new AsyncPostBackTrigger();                triger.ControlID = btn.ID;                triger.EventName = "Click";                UpdatePanel1.Triggers.Add(triger);                index++;            }        }

最好用ajax或者jQuery做，updatePanel控件貌似性能不怎么好
