            // Instantiates datastore with datawindow: d_department.
            var department = new DataStore("d_department", _context);

            // Defines what to do when DeleteRow is being executed.
            department.RowDeleting +=
                (object sender, DwRowChangeEventArgs args) =>
                {
                    Console.WriteLine("You are deleting a row!");
