Among the differences between version 1.1 and 2.0 of .NET Framework is the many new
controls. Even though most of them don’t add new functionality they make a lot of
things much easier and cleaner than before. Some of these new controls in ASP.NET
are the HTML controls HtmlHead, HtmlMeta and HtmlLink.
They don’t add much new functionality by them selves, but look at how clean the code
becomes when you use them:
protected void Page_Load(object sender, EventArgs e)
{
AddMetaContentType();
AddMetaTag("keywords", "word1,
word2, word3...");
AddMetaTag("description", "bla
bla bla");
AddStyleSheet("/includes/style.css");
}
private void AddMetaContentType()
{
HtmlMeta meta
= new HtmlMeta();
meta.HttpEquiv
= "content-type";
meta.Content
= Response.ContentType + "; charset=" +
Response.ContentEncoding.HeaderName;
Page.Header.Controls.Add(meta);
}
private void AddMetaTag(string name, string value)
{
HtmlMeta meta
= new HtmlMeta();
meta.Name
= name;
meta.Content
= value;
Page.Header.Controls.Add(meta);
}
private void AddStyleSheet(string relativePath)
{
HtmlLink link
= new HtmlLink();
link.Href
= relativePath;
link.Attributes["type"]
= "text/css";
link.Attributes["rel"]
= "stylesheet";
Page.Header.Controls.Add(link);
}
This is much more cleaner than adding literal controls to the page header or whatever
trick you used before. Just remember to add a runat="server" attribute to the <head>
tag of your web page.
