You can't use any Controls outside of a WebForm. This is just a guess, but I
would expect that the string passed to the function is converted to a
Control prior to inserting it in the Page (all HTML in the Page Template is
converted to Controls at run-time). Is there some special reason you don't
want a form tag in the Page? If so, you could always use the old
Response.Write() method.
