如何将Calendar日历控件中文星期变成英文

1、给Calendar添加个PreRender属性

程序代码

protected void Calendar1_PreRender(object sender, EventArgs e)
        {
            Thread myThread = Thread.CurrentThread;
            CultureInfo myClt = (CultureInfo)myThread.CurrentCulture.Clone();
            myClt.DateTimeFormat.DayNames = new string[] { "Sun","Mon", "Tus", "Wes", "Thu", "Fri", "Sat" };            
            myClt.DateTimeFormat.FirstDayOfWeek = DayOfWeek.Monday;
            myThread.CurrentCulture = myClt;  

        }

2、记得把Calendar的DayNameFormat="Full" 默认是Short值，如果不改，是无法显示出来的。
效果如图：


3、如果需要给星期天加个背景，可在DayRender事件中添加

程序代码

//星期日添加背影颜色
            if (e.Day.Date.DayOfWeek == DayOfWeek.Sunday)
            {
                e.Cell.BackColor = System.Drawing.Color.YellowGreen;
            }

4、给日期下方添加文字

程序代码

DateTime dt = new DateTime(2009, 6, 3);
            if (e.Day.Date.Date == dt)
            {
               e.Cell.Controls.Add(new LiteralControl("<br>*"));  
            }
