The extension methods needed for performing Bulk Update
are located in the Telerik.OpenAccess
namespace. Your project also needs to have a reference to the Telerik.OpenAccess.35.Extensions
assembly. However the lack of the respective using statement for the namespace or assembly reference would generally result in a different error.
Based on the provided error description it appears that the Set method may be called with incorrect argument. We would need some additional information to investigate the situation further. Could you please provide us with the code
you are using for the bulk update operation and the structure
of the persistent type(s) you attempt to update?
We are looking forward to your feedback.
OpenAccess ORM is now Telerik Data Access
. For more information on the new names, please, check out the Telerik Product Map
