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" %>
<script runat="server">
private void Calendar1_SelectionChanged( System.Object sender, System.EventArgs e )
{
TextBox1.Text = Calendar2.SelectedDate.ToShortDateString(); Panel1.Visible = false; 
} private void OnClick( System.Object sender, System.EventArgs e ) { if ( Panel1.Visible ) { Panel1.Visible = false; } else { Panel1.Visible = true; } }
</script><!-- Insert content here --><asp:TextBox id="TextBox1" runat="server"></asp:TextBox><asp:Button id="Button1" onclick="OnClick" runat="server" size="43" Text="..." height="22" width="35" type="button"></asp:Button><div id="divCalendar"> <asp:Panel id="Panel1" runat="server" Width="172px" Height="182px" Visible="False"> <asp:Calendar id="Calendar2" runat="server" Width="200px" Height="180px" OnSelectionChanged="Calendar1_SelectionChanged" BorderWidth="2px" BackColor="White" ForeColor="Black" Font-Size="8pt" Font-Names="Verdana" BorderColor="#999999" BorderStyle="Outset" DayNameFormat="FirstLetter" CellPadding="4"> <TodayDayStyle forecolor="Black" backcolor="#CCCCCC"></TodayDayStyle> <SelectorStyle backcolor="#CCCCCC"></SelectorStyle> <NextPrevStyle verticalalign="Bottom"></NextPrevStyle> <DayHeaderStyle font-size="7pt" font-bold="True" backcolor="#CCCCCC"></DayHeaderStyle> <SelectedDayStyle font-bold="True" forecolor="White" backcolor="#666666"></SelectedDayStyle> <TitleStyle font-bold="True" bordercolor="Black" backcolor="#999999"></TitleStyle> <WeekendDayStyle backcolor="#FFFFCC"></WeekendDayStyle> <OtherMonthDayStyle forecolor="#808080"></OtherMonthDayStyle> </asp:Calendar> </asp:Panel></div>
调用页面代码：
<%@ Page Language="C#" %><%@ Register TagPrefix="expo" TagName="CusCalender" Src="NewFile.ascx" %><script runat="server"> // Insert page code here //</script><html><head> <title>Testing the Calendar</title></head><body> <form runat="server"> <expo:CusCalender id="cusCalender" runat="server"></expo:CusCalender> </form></body></html>
