This example shows how to use a UserControl and a Code-behind to pass values using user-defined properties. Here is the code: The webpage. Test.aspx <%@ Page Language="C#"%>
<%@ Register TagPrefix="Prefix" TagName="Test" src="uc_test.ascx"%>
<HTML>
<HEAD></HEAD>
<BODY>
<Prefix:Test CustomProp="No" CustomProp2="Yes" id=Test1 runat="server" />
</BODY>
</HTML>The User-Control page uc_test.ascx <%@ Control Language="c#" Inherits="uc_test" SRC="uc_test.ascx.cs"%>Code-Behind - uc_test.ascx.cs using System;
