49|error|500|The field 'Id' is read-only and can't be changed.|
If I enable the column Id i don't have any error but the item is not update but created.

I try also to use UpdateCommand Event and UpdateParameters but i received the same error.
Any experience with LLBLgen and Telerik ?

Thanks is advance for your help.

Edwin.
