I have a VB 2008 program over the Northwind DB customer table.It uses LINQ to add, delete and edit records.

I've set the Customer ID field as the primary key in the DT. I then bind everything together with a binding mavigator.
So far so good, Adding & Editing works nicely the DGV & customer table . [code]...
