Watin for dynamic web?

Question

I had use in the past Firebug to identify elements on a web page and then created windows app with c# and watin to interact with those pages. The problem is that I encounter this web page that can only be seen with IE 9 ( firebug is out of the picture) and most elements are created dynamically. Is there anything to read those elements and/or a place for watin references to interact with parent/child, thanks
