    Im facing some problem here with row update in GridPanel. Im using LINQ as ORM and in GridPanel im using RowEditor plugin. I can find the updated data from grid and datacontext.submitchange is executing without any exception but there is no impact in DB table. I think im missed something. Could you please show me the snippets on how you used your GridPanel to work it with linq?

    Though this thread of your's is 2+ years old, yet im hoping you might notice my post and help me with my issue.
