How do you modify a CSS style in the code behind file for divs in ASP.NET?

Question

I'm trying to modify a CSS style attribute for a div based on the information I get from a database table in the code behind of my aspx page. The following is essentially what I am trying to do, but I get errors.

Aspx:

<div id="testSpace" runat="server">     Test </div> 

Code Behind:

testSpace.Style = "display:none;"     testSpace.Style("display") = "none"; 

What am I doing wrong?

Answer 1

testSpace.Style.Add("display", "none");
