Hi,
You can use either the Register directive in your aspx file or the controls tag in web.config.
The problem with both is that you would have to add an empty class/file for it to work. With Register:
<%@ Register TagPrefix="TEST" Assembly="YourProjectAssembly" %>
--> add class THING to project
<%@ Register TagPrefix="TEST" TagName="THING" src="THING.ascx" %>
--> add empty ascx file called THING.ascx
or in web.config, you can use the controls tag. Check out http://weblogs.asp.net/scottgu/archive/2006/11/26/tip-trick-how-to-register-user-controls-and-custom-controls-in-web-config.aspx.
But wouldn't it be easier to add a div or something with id="test"?
