Your application has a user control named UserCtrl.ascx. You write the following code fragment to create a Web page
named Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" %>
<html>
...
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lblHeader" runat="server"></asp:Label>
<asp:Label ID="lbFooter" runat="server"></asp:Label>

</form>
</body>
</html>
