一个关于日历控件的问题!

<html>
<head>
<script language="C#" runat="server">        void Date_Selected(object s, EventArgs e) {
            Label1.Text = "你选择的日期是: " + Calendar1.SelectedDate.ToShortDateString();
        }    </script>
</head>
<body>
<form runat="server" enctype="multipart/form-data">
<asp:Calendar id="Calendar1" onselectionchanged="Date_Selected" TitleStyle-BackColor="#AAAADD" DayHeaderStyle-BackColor="#FFFFCD" runat="server" />
<p>
<asp:Label id="Label1" runat="server" />
</form>
</body>
