Redirect parent page to Error page if error occurs in IFRAME child page in ASP.Net

I have a data driven asp.net website with frames on the top, left, right and center screen.  If a page generates an error on any of the frames, I want to redirect the whole site back to the Default.aspx.  Currently, when a frame page errors in one of the frames, that frame gets the error pages.  Site is http://shopbuyname.com.  Is this something that can be handled?  Is there a better way?  Thanks
