Adding Style at run time

Hello,
I am a ASPX page where I have defined the style for the head element.
******************
<head runat="server" >
<style type="text/css">
.MyClass
{
background-color: aqua;
}
</style>
</head>
******************

However, instead of doing at design time, I need to do this at run time..
Can someone help how to add this @ run time to the page?.

Thanks,
Ganesh

You could declare the link id for the stylesheet with a runat sever tag and
use an external stylesheet

<head>
<link id="cssStyleSheet" rel="stylesheet" type="text/css" runat="server" />
</head>
Sub Page_Load(Sender As Object, E As EventArgs)
If Not (IsPostBack)
cssStyleSheet.Attributes.Add("href","Stylesheetname.css")
End If
End Sub

Hi Ganesh,

Here's some code that creates a style in code at runtime.

Let us know if this helps?

Hi Ganesh,

You're welcome, and here's a further reference that I just found:

Sure, that code snippet works fine Ken but the context of the head element
is much broader than a snippet infers so I thought I'd throw in the big
picture in case the OP is a serious developer who may be currently ignorant
but wants to learn how to master the framework. Once finding and loading the
documentation for a class such as the HtmlHead class the menu for MSDN
documentation will also display all the related classes such as HtmlLink,
HtmlMeta and so on. Very insightful wouldn't you agree?

As you may recall, one of the most frequently asked questions used to be
"[should I | how do I] do this using my own code or is there a class already
built in the framework?" That was early in the days when those who really
wanted to learn to be masterful were interested in delving into the
framework.
