如何用 Calendar 控件来做日程管理

 前几天领导给我任务是:写一个日程管理功能. 
 在此以前没有写过这样的功能,接到任务,没有一点思路.
 最后在网上找了些资料,但是没有找的什么好的资料.只找到可以用 Calendar 控件来实现.

最后我花了天的时间写好了日程管理功能,现在我把它拿出来和大家分享,也希望各位多多指教.
1.我要说的是主要用Calendar 控件的 DayRender 事件
              /// <summary>
        /// 读取日程信息和设置日程日历
        /// 周海军　2007-03-06
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void calSchedule_DayRender(object sender, DayRenderEventArgs e)
        {
            // 自定义显示内容
            // 获取表示呈现在Calendar控件中的日期
            CalendarDay d = ((DayRenderEventArgs)e).Day;
            CalendarDay day = e.Day;
            // 获取表示呈现在Calendar控件中的单元格
            TableCell c = ((DayRenderEventArgs)e).Cell;
            //c.Width =230;
            // 创建农历转换类
            // Lunar lr = new Lunar();
            if (d.IsOtherMonth)
            {
                c.Controls.Clear();
            }
            else
            {
                DateTime FDate = new DateTime();
                string Subject;
                DateTime Date = new DateTime();
                Date = d.Date;
                try
                {
                    c.Controls.Clear();
                    //显示当天日期，并且超链接
                    c.Controls.Add(new LiteralControl("<a href='SchedByDay.aspx?date=" + d.Date.Year.ToString() + "-" + d.Date.Month.ToString() + "-" + d.Date.Day.ToString() + "' style='color:#003080;FONT-SIZE: 12px;'>" + d.Date.Day.ToString() + "</a>"));
                    c.Controls.Add(new LiteralControl("&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;"));

                    // 显示超链接，自定义一个HyperLink，并设置好属性
                    HyperLink aHyperLink = new HyperLink();
                    aHyperLink.ImageUrl = "../images/add_small.gif";
                    aHyperLink.ToolTip = "新增个人日程";
                    aHyperLink.NavigateUrl = "Plan_AddEdit.aspx?Id=add&date=" + d.Date.Year.ToString() + "-" + d.Date.Month.ToString() + "-" + d.Date.Day.ToString() + "";
                    //
                    c.Controls.Add(aHyperLink);

                   
                }
                catch (Exception exc)
                {
                    Response.Write(exc.ToString());
                }
                // 读出该天的信息
               
                Plan_Day plan_day=new Plan_Day();
                DataTable Dt = Plan_DayInfo.Plan_GetBy_DateAndUser(Date.ToString("yyyy-MM-dd"),InUser);
               
                // 显示该天所有信息
                try
                {
                    if(Dt!=null)
                    {
                        for (int i = 0; i < Dt.Rows.Count; i++)
                        {
                            // 得到日程主键PlanID
                            int PlanID = Int32.Parse(Dt.Rows[i]["Plan_ID"].ToString());
                            // 得到日程安排日期
                            FDate = DateTime.Parse(Dt.Rows[i]["Plan_Date"].ToString());
                            // 只获取小时和分钟部分
                            string FDate_hour = FDate.Hour.ToString();
                            string FDate_Minute = FDate.Minute.ToString();
                            if (FDate_Minute == "0")
                            {
                                FDate_Minute = "00";
                            }
                            // 得到日程标题
                            Subject = Dt.Rows[i]["Plan_Subject"].ToString();
                            // 只取标题的前4位
                            if (Subject.Length > 4)
                            {
                                Subject = Subject.Substring(0, 4);
                                Subject += "..";
                            }
                            HtmlAnchor a = new HtmlAnchor();
                            // 指向日程的详细信息
                            a.HRef = "Plan_AddEdit.aspx?Id=" + PlanID + "";
                            a.InnerText = "☉"+Subject+"";
       a.Attributes.Add("style", "FONT-SIZE: 12px;");
                            c.Controls.Add(new LiteralControl("&nbsp;" + "&nbsp;" + "&nbsp;" + "&nbsp;"));
                            c.Controls.Add(new LiteralControl("<br>"));
                            c.Controls.Add(a);

                        }
                        e.Cell.Attributes["onmouseout"] = "JavaScript:this.style.backgroundColor='';";
                        e.Cell.Attributes["onmouseover"] = "JavaScript:this.style.backgroundColor='#e8e8e8';";
                    }
                }
                catch
                {
                    return;
                }
            }
        }
