Hi Maya

The links which you provided is helpful and its working fine . Thanks for providng me a solution.

thanks. that worked. it was infragistics4  and infragistics35 mismatch.

Hello Bill,

Make sure that it’s the same service release version. For example if all your reference point to:Assembly="Infragistics4.Web.v12.1, Version=12.1.20121.1005…. 

Then make sure that the assemblies you reference are of the same version.If there is a mismatch for example if the dll version is: 12.1.20121.2020.Then you need to either change the references to point to that version or change the assemblies to match the version.

Let me know if you need further assistance.

Best Regards,

I have used Web Data Grid and Web Progress bar in one of my asp.net application. Now when  i published the code and tried to load on client site it is not loading page.

 I have added reference in web.config file and placed dlls in bin folder on production server. but it gives me error unable to load assembly 'Infragistics.Web.v12.1'

i believe i have followed the links above regarding deployment. i have version 12.1

thanks.

Bill
