How to edit CSS style of a div using C# in .NET

Question

I\'m trying to grab a div\'s ID in the code behind (C#) and set some css on it. Can I grab it from the DOM or do I have to use some kind of control?

To expand on Peri's post & why we may not want to use viewstate the following code:

style="<%= _myCSS %>"

Protected _myCSS As String = "display: none"
Is the approach to look at if you're using AJAX, it allows for manipulating the display via asp.net back end code rather than jquery/jscript.
