Hi Terry,
In my web app the page on which i m putting this ajaxuploader control is derived from a pagebase class and also a masterpage. I made one test page just like my other page(deriving from pagebase and also from master page) and put the ajaxuploader control and ran it in firefox and the onfileuploaded event got fired. It worked fine on test page in my webapp....
I do not know what is choking the event to get fired on the real page !!
Can we do a gotomeeting?
