I am trying to write an adapter for anchor tag or a hyperlink control.  However I do not understand how to hook up the adapter to the hyperlink.  I used the sample class WebControlAdapterExtender and I am trying to modify it just for a text box control.  Now how do I make a hyperlink on a page use the custom adapter instead of the built in hyperlink writer.

 We are trying to do this because we want to use hyperlinks with runat=server however the onClick javascript it generates is not accessible.  My organization requires WCAG Priority 1 compliance.

Thanks for the help.
