Hi Tim. I'm using Windows forms. I'm not using a tab control. I have a table layout with the grid on the left and the textboxes on the right. This is very simple right now. When I navigate through the grid it does update my textboxes so the datasource is bound to the grid and the textboxes. I have no rules in code. The table has an auto gen pk, 2 varchar fields, and a timestamp field. The only code I have written is for the grids autogenfields. It is set to false. Do you think the timestamp column is the problem?

Thanks.
