How do I get a Hyperlink Click Event from within a GridView

I know the solution to this is to not use a Hyperlink but a LinkButton instead. The problem with a LinkButton is it uses a PostBackUrl event (not navigation), which causes an 405 error because I am dynamically linking to PDF files. All I want this hyperlink to do is cause the row to be selected (CommandName = Select), but I cannot figure out how.
