please help me .

Hello Lourdu,

Thank you for contacting us.

This error can be thrown when there is an inconsistency in the version of the OpenAccess assemblies. For example you could have one version of the product installed, but some of our dll's with another version is present in your bin folder and gets loaded in the Application Domain. It usually happens when there is a difference between the versions of Telerik.OpenAccess.dll and Telerik.OpenAccess.35.Extensions.dll.

I hope this provides useful for you as well as anyone in the community that might encounter this issue.

Regards,
Yavor Slavchev
