Did you know that you may make any HTML tag in a web form into a web forms control by putting runat="server" inline in it?

Then from the C# code behind you may do things like set the .Visible equal to false, etc. There are a few common things one may generically do with any control such as set the Visible setting. You will also need an ID="yournamehere" inline setting to give a handle to use at the server side.
