数据绑定--单个数据

      其实ASP.NET 2.0里面有很多和ASP里指定动态显示的东西.
      页面代码:

    <form id="form1" runat="server">
        <asp:Label ID="Label1" runat="server"> The result of 7 plus 4 is <%# 7 + 4 %> </asp:Label> <br /> <br />
        <asp:Label ID="Label2" runat="server"> The result of 7 minus 4 is <%# 7 - 4 %> </asp:Label> <br /> <br />
        <asp:Label ID="Label3" runat="server"> The current date and time is <%# DateTime.Now %> </asp:Label> <br /> <br />
        <asp:Label ID="Label4" runat="server"> The physical URL of this page is <%# Request.PhysicalPath %> </asp:Label> <br /> <br />
        <asp:Label ID="Label5" runat="server"> The user's preferred language is <%# Request.UserLanguages[0] %> </asp:Label> <br /> <br />
        <asp:Label ID="Label6" runat="server"> Universal Coordinated Time is <%# UtcTime %> </asp:Label> <br /> <br />
        <asp:Label ID="Label7" runat="server"> Time in New York City is <%# GetTimeInTimeZone(-5) %> </asp:Label> <br /> <br />
        <asp:Label ID="Label8" runat="server"> Top product ID is <%# TopProductID %> </asp:Label> <br /> <br />       
        <asp:TextBox ID="TextBox1" runat="server" Text=" <%# TopProductID %> "/> <br /> <br />       
        <asp:HyperLink ID="HyperLink1" NavigateUrl='<%# "~/DisplayProduct.aspx?ProductID=" + TopProductID %>' runat="server">Display product</asp:HyperLink> <br /> <br />
 </form>
