   <source lang="csharp">

<%@ Page %> <%@ Reference Control="control.ascx" %> <script runat="server" language="C#"> void Page_Load(Object sender, EventArgs e) {

   Control sampleControl = LoadControl("Control.ascx");

User control with asp control

   <source lang="csharp">

<%@ Page %> <%@ Register TagPrefix="user" TagName="SampleControl" Src="control.ascx" %> <user:SampleControl runat="server" />

User control with no user interface (VB.net)
