C# 是创新性的新式编程语言

1.属性
ShowGridLines=true
SelectDate当前选择的日期
SelectMode,决定用户可以选择的类型
2.事件
SelectionChanged,用户选择时激发
3.例子
a.设置当前日期为选择日期
this.Calendar1.SelectedDate=System.DateTime.Now;
b.用户选择时的事件
private void Calendar1_SelectionChanged(object sender, System.EventArgs e)
{
	StringBuilder builder=new StringBuilder();
	foreach(DateTime date in this.Calendar1.SelectedDates)
	{
		builder.Append(date.ToLongDateString());
		builder.Append("<br>");
	}
	Output.Text=builder.ToString();

}
c.设置选择范围
DateTime start=new DateTime(2002,1,1);
DateTime end=new DateTime(2002,1,3);
this.Calendar1.SelectedDates.SelectRange(start,end);
this.Calendar1.VisibleDate=start;
4.高级自定义
a.在单元格添在文本
private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
	e.Cell.Width=80;
	e.Cell.Height=64;
	string html="<br><font color=\"red \" face=\"verdana\" size=\"1\">"+
		"Christmas</font>";
	if(e.Day.Date.Month==11&&e.Day.Date.Day==25)
	{
		e.Cell.Controls.AddAt(0,new LiteralControl("<br>"));
		e.Cell.Controls.Add(new LiteralControl(html));
	}
}
b.限制用户选择星期六、星期日
private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
	e.Day.IsSelectable=!(e.Day.Date.DayOfWeek==DayOfWeek.Saturday||
	e.Day.Date.DayOfWeek==DayOfWeek.Sunday);

}
c.防止今天之前被选择
e.Day.IsSelectable=e.Day.Date>=DateTime.Today;
