Remove the updatepanel ans see if it getting called, if not then try to delete the click event and add it again
http://blogs.visoftinc.com/2007/09/23/asp-net-ajax-updatepanel-not-working-common-problems/
remove <xhtmlConformance mode="Legacy"/> from the web.config
Or you can delete the old converted web.config and then simply create a new one and
