Hi,

Because of some incompatibilities to IE9, we had to upgrade Telerik Ajax controls recently from 2009.3.1103.35 to 2011.2.915.35.

It worked fine locally and on the Beta server but it won't work on the Live environment where we have the files on a net share.

It works properly with the old Telerik version though. We DO have IntranetZone set as FullTrust as indicated in similar posts. Otherwise even the old version of Telerik controls wouldn't work.

Could you please advise? We need this upgrade up and running as soon as possible so that the IE9 users can make use of the Teletik controls.

Thank you,
Carlos Guarany

Hello Carlos,

Based on the supplied information it is hard to say what is causing the described issue at your end. Could you please elaborate a bit more on your scenario. How do you bind the RadGrid? What data source do you use? Also it will be helpful if you post your aspx page markup with the related code behind file or send us a small runnable example which demonstrates the described issue. Thus we will be able to gather more details about your scenario, debug the application and investigate the problem.
Looking forward for your reply.

Regards,
Radoslav
