Template Form overrides?

I am looking at some code that references an external dll that overrides some of the methods of the usual html form class. I want to include these overrides within the code-behind of the asp.net template but cannot workout how to do this.

Any ideas?

No worries worked it out! Needed to place a reference in the header:

e.g.

<%@ Register TagPrefix=“myForm” Namespace=“MyControls”%>
