Calendar OnDayRender 动态添加控件问题

[古都老码农]

先看代码：

//日历事件
protected void calSchedule_DayRender(object sender, DayRenderEventArgs e)
        {
            //自定义显示内容
            CalendarDay calDay = ((DayRenderEventArgs)e).Day;
            //获取表示呈现在控件中的单元格
            TableCell tc = ((DayRenderEventArgs)e).Cell;
            //农历转换对象
            Common.CNDate dt = new Common.CNDate(calDay.Date);
            if (calDay.IsOtherMonth)
            {
                tc.Controls.Clear();
            }
            else
            {
                //显示日历控件的方法
                IList<XaSiteModel.Site_WorkLog> list = WorkBll.GetModelList(string.Format("CreateName='{0}' and AddTime between '{1}' and '{1}'",User.Identity.Name,calDay.Date)); //根据用户和时间查询日程的信息
                
                HyperLink aHyperLink = new HyperLink();
                aHyperLink.ImageUrl = "~/images/add_Schedule.gif";
                aHyperLink.ToolTip = "新增个人日程";   //提示
                aHyperLink.NavigateUrl = "~/Admin/Site_WorkLog/Site_WorkLogAdd.aspx"; //路径
                tc.Controls.Add(new LiteralControl(" " + " " + " "));
                tc.Controls.Add(aHyperLink);
                tc.Controls.Add(new LiteralControl("<br>" + dt.GetLunarHolDay())); //得日期
                if (list.Count > 0 )  //如果日程的集合和预约人的集合都存在则显示相应的信息
                {
                    XaSiteModel.Site_WorkLog WrokMod = new XaSiteModel.Site_WorkLog();

                    WrokMod = list[0];
                    if (list.Count > 1)
                    {
                        ShowSchedule(WrokMod.ID, WrokMod.AddTime.ToShortTimeString(), WrokMod.LogTitle, calDay.Date, tc);
                        showScheduleAll(WrokMod.CreateName, calDay.Date, tc);
                    }
                    else
                    {
                        ShowSchedule(WrokMod.ID, WrokMod.AddTime.ToShortTimeString(), WrokMod.LogTitle, calDay.Date, tc);
                    }
                }
            }
        }

//根据用户Id，日程ID，开始时间和标题等条件在日历控件中显示日程 [日历控件]
        public void ShowSchedule(long ID, string beginTime, string title, DateTime date, TableCell tc)
        {
            LinkButton LinkBtn = new LinkButton();
            LinkBtn.ID = "LinkBtn" + ID.ToString();
            if (title.Length > 4)
            {
                LinkBtn.Text = "◎ " + title.Substring(0, 4) + "...";
            }
            else
            {
                LinkBtn.Text = "◎ " + title;
            }
            LinkBtn.CommandArgument=ID.ToString();
            LinkBtn.Attributes.Add("href", "javascript:__doPostBack('" + calSchedule.UniqueID + "$" + LinkBtn.ClientID + "','')");
            LinkBtn.Click += new EventHandler(LinkBtn_Click);
            tc.Controls.Add(new LiteralControl(" " + " " + " "));
            tc.Controls.Add(new LiteralControl("<br>"));
            tc.Controls.Add(LinkBtn);
            

        }

        protected void LinkBtn_Click(object sender, EventArgs e)
        {
            ExtAspNet.Alert.ShowInTop("sfsdfsff");
        }

linkbuttion点击后，事件不触发，这是怎么回事呢！！很急，高手速进！！

ExtAspNet.Alert.ShowInTop("sfsdfsff");
这段不触发吧
