This is what I do when I evaluate checkbox per row:

foreach (DataGridViewRow row in dg.Rows)
        {
            if (Convert.ToBoolean(row["checkColumnName"].ToString())
            {
                // do checked thing
            }
            else
            {
                // do unchecked thing
            }
        }
