对ASP.Net所知甚少，用 Web Matrix 作了一个日期选择控件，让大家见笑了 
控件代码如下：
```
... @?Control?ClassName = " CustomCalender " ?autoeventwireup = " false " ?Language = " C# " ?targetschema = " http://schemas.microsoft.com/intellisense/ie5 " ?
1  < script? runat ="server" > ...
2
3 ????private? void ?Calendar1_SelectionChanged(?System.Object?sender,?System.EventArgs??e??)
4  ???? ... {
5 ????????TextBox1.Text? = ?Calendar2.SelectedDate.ToShortDateString();
6 ????????Panel1.Visible? = ? false ;
7 ????
8 ????}
9 ????private? void ?OnClick(?System.Object?sender,?System.EventArgs??e??)
10  ???? ... {
11 ????????? if ?(?Panel1.Visible?)
12  ????????? ... {
13 ????????????Panel1.Visible? = ? false ;
14 ?????????}
15 ????????? else
16  ????????? ... {
17 ?????????????Panel1.Visible? = ? true ;
18 ?????????}
19 ????
20 ????}
