日历控件几个问题各位老大多多帮助~！

1. 控件有几种格式，你选择的格式不同显示的标题不同
2.添加Calendar控件的 OnDayRender 事件
<asp:Calendar OnDayRender="OnDayRender" RunAt="server" />
    .
    .
    .
  void OnDayRender (Object sender, DayRenderEventArgs e)
  {
//再这里添加修改颜色
      if (e.Day.Date.Month == 1 && e.Day.Date.Day == 21)
      {
           //...
      }
      if((int)(e.Day.Date.DayOfWeek)==5) //星期六
{
e.Cell.BackColor =System.Drawing.Color.Gold;
}

  }

问题1:
   没有属性可以改，应该算是Calendar控件的一个BUG，我研究过，它完全是根据英文版的改过来的，所以，只显示星。所以我也是把head 给隐藏了，自己做了个Table显示星期，最上端，自己定义导航按钮。问题2 ：
   在事件private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
   //m_date 为自己计算的日期
  if(e.Day.Date == m_date)
   {
e.Cell.BackColor = System.Drawing.Color.LightCyan;
   }
}

up以下~！
我现在最郁闷的是怎么不用sql语句实现一个日期区间的计算？意思是说用日历控件得到日期区间，然后点击这个区间的日期得到的都是这个日期区间的开始和结束日期SelectedDates是做什么的好像是个数组把~！怎么用没看明白
