I think you're complicating your life needlessly.
If you don't like that method, use this :
<%@ Page Language="C#" AutoEventWireup="True" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>
Changing a Page's Background Color
</title>
<script runat="server">
void SubmitBtn_Click(object Source, EventArgs e)
{
Body1.Attributes["bgcolor"] = ColorSelect.Value;
}
</script>
</head>
<body id="Body1" runat="server">
<h3>Changing a Page's Background Color</h3>
<form id="Form1" runat="server">
<p></p>
Select a background color for the page: <p></p>
<select id="ColorSelect" runat="server">
<option>White</option>
<option>Wheat</option>
<option>Gainsboro</option>
<option>LemonChiffon</option>
</select>
<input id="Submit1" type="submit" runat="server" value="Apply" onserverclick="SubmitBtn_Click"/>
</form>
</body>
</html>

You should be able to insert that code into code-behind,
almost as it is. I wrote it inline, because I prefer inline coding.
Notice that all I'm doing is adding an id attribute (body1) to the body,
and then changing the bgcolor of that HtmlGenericControl.
All you'd need to do is submit the form programmatically,
with whatever value you are going to give to "Body1.Attributes["bgcolor"]
You can see the above code working at :
