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

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?

If you're newing up an element with initializer syntax, you can do something like this:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Attributes = { ["style"] = "min-width: 35px;" }
    },
  }
};

Or if using the CssStyleCollection specifically:

var row = new HtmlTableRow
{
  Cells =
  {
    new HtmlTableCell
    {
        InnerText = text,
        Style = { ["min-width"] = "35px" }
    },
  }
};

It's an HtmlGenericControl so not sure what the recommended way to do this is, so you could also do:

testSpace.Attributes.Add("style", "text-align: center;");

or

testSpace.Attributes.Add("class", "centerIt");

or

testSpace.Attributes["style"] = "text-align: center;";

or

testSpace.Attributes["class"] = "centerIt";

Another way to do it: 

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

or

testSpace.Style["background-image"] = "url(images/foo.png)";

in vb.net you can do it this way:

testSpace.Style.Item("display") = "none"
