Error while adding new controls

Hi,

This is Kesav. I posted the same question and I got following reply.
-------------------------------------
Hi Kesav,

Please try the following Migration utilities shipped with the Syncfusion installation.

Start --> All Porgrams --> Syncfusion --> Essential Studio 4.2.0.37 --> Utilities --> Migration --> Convert Resx(Framework 2.0)

Please try this utility and let us know if this helps.

Thank you for your interest in Syncfusion Essential Studio.

Regards,
Nanda

I did this, eventhough the problem has not been solved. Still I am getting the same problem.

I think the problem related to Syncfusion Grid.
(Please have a look into the following exception)

Please provide a solution.

Thanks and Regards

Hi Kesav,

The recommended solution is to remove the older version ( 2.x/3.x ). So, please uninstall the older version and check for any reference files in the GAC folder ( C:\WINDOWS\assembly ) for the version 2.1.0.9 and delete them. Then upgrade to the new version ( 4.2.0.37 ).

Please try these steps and see if it helps.

- First change the reference in the project to 4.x files
- and then try converting using the Syncfusion .resx utility

Let me know if you need any further assistance.

Best regards,
Haneef
