So you edit one record at a time (at those external controls only). I would not put validation to container.lostfocus, it may get triggered inadvertently when user just clicked outside the container.
Basically, I would either have Add,Edit,Accept (with validation),Cancel buttons or have all validation in grid (i.e. GetNextModified) before TableUpdate.
