The following code example demonstrates using the HtmlLink control to programmatically add a style sheet to a Web page.
<%@ Page Language="VB" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) \' Define an HtmlLink control. Dim myHtmlLink As New HtmlLink() myHtmlLink.Href = "~/StyleSheet.css" myHtmlLink.Attributes.Add("rel", "stylesheet") myHtmlLink.Attributes.Add("type", "text/css") \' Add the HtmlLink to the Head section of the page. Page.Header.Controls.Add(myHtmlLink) End Sub </script> <html > <head id="head1" runat="server"> <title>HtmlLink Example Page</title> </head> <body> <form id="form1" runat="server"> <h1>HtmlLink Example Page</h1> This is some text in the body of the Web Forms page. </form> </body> </html>
<%@ 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"> protected void Page_Init(object sender, EventArgs e) { // Define an HtmlLink control. HtmlLink myHtmlLink = new HtmlLink(); myHtmlLink.Href = "~/StyleSheet.css"; myHtmlLink.Attributes.Add("rel", "stylesheet"); myHtmlLink.Attributes.Add("type", "text/css"); // Add the HtmlLink to the Head section of the page. Page.Header.Controls.Add(myHtmlLink); } </script> <html > <head id="head1" runat="server"> <title>HtmlLink Example Page</title> </head> <body> <form id="form1" runat="server"> <h1>HtmlLink Example Page</h1> This is some text in the body of the Web Forms page. </form> </body> </html>
To run the preceding code example, you need a cascading style sheet (CSS) named Stylesheet.css, containing the following code, saved in the same directory as your Web site.
body {
padding-left: 11em;
font-family: Verdana, "Times New Roman",
Times, serif;
color: blue;
background-color: silver }
h1 {
font-family: Helvetica, Geneva, Arial,
SunSans-Regular, sans-serif;
color: purple }
