Good day everybody i been been on this issue for day now. I have a website application i did with visual studio 2008 containing lots of reports and they were all working fine. When i more to visual studio 2012, i change all the microsoft report reference from 9.0.0.0 to 11.0.0.0 and also changed handler from 9.0.0.0 to 11.0.0.0 in both the aspx pages and web.config. When i runned the report, report viewer was not showing and there is no error exception/error message. I want to know if there is anything am not doing well because i have debugged the report many times without any exception. Please i need help
