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?

Answer 1

How do you do this without runat="server"? For example, if you have a

...and try to update it from within an Updatepanel it will never get updated.

However, if you keep it as an ordinary non-server HTML control you can. Here's the Jquery to update it:

$("#body1").addClass('modalBackground');

How do you do this in codebehind though?
