Server Controls

For those of you writing custom server controls in ASP.NET - by default, the controls tend to render everything within span blocks.

In our case, we wanted it to use divs instead, here's how:

protected override HtmlTextWriterTag TagKey
{
    get
    {
        return HtmlTextWriterTag.Div;
    }
}

UPDATE: That is, of course, only if you use WebControl vs. Control.
