<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">  
  
  void Page_Load(object sender, System.EventArgs e)
  {

    // Programmatically create an HtmlHead control.
    HtmlHead head = new HtmlHead();

    // Add the page title to the header element.
    HtmlTitle title = new HtmlTitle();
    title.Text = "HtmlHead Constructor Example";
    head.Controls.Add(title);

    // Add a defined style sheet that contains the body
    // style to the HtmlHead control.
    HtmlLink link = new HtmlLink();
    link.Href = "~/Stylesheet.css";
    link.Attributes.Add("rel", "stylesheet");
    link.Attributes.Add("type", "text/css");
    head.Controls.Add(link);

    // Add the HtmlHead controls to the Controls
    // collection of the page.
    Page.FindControl("HtmlElement").Controls.AddAt(0, head);

  }
  
</script>
