John,

>Its a very simple scenario - the primary table is meetingattendance, members and meetings are lookup tables. There are 2 comboboxes to input the information. The members combo bindingsource = members table, bindingsourcedisplaymember = members.surname, bindingsourcevaluemember = members.memberid and the bindingvaluesourcemember = meetingattendance.memberid.
>When a record is saved, the view in the only dataviewgrid on the form is refreshed to display the full details ie the members surname and not the memberid.
>I want to sychronize the records in the view to the meetingattendance table so that if I need to delete a record I just select a record in the dataviewgrid and then click the delete button.

OK, then you can just call the DataGridView's GetCurrentRowPK() and pass that to the MeetingAttenance business object's Delete(object primaryKeyValue) method.

Best Regards,
