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

            // Retrieves rows from the database for datastore.
            datastore.Retrieve();

            Console.WriteLine("After Retrieve, Rowcount: {0}",
                              datastore.RowCount);

            // Sets the value for the name column in the last row to "New Department"
            datastore.SetItem(datastore.RowCount - 1, "name", "Engineering New");

            int lastRow = datastore.RowCount - 1;
            Console.WriteLine("Gets the original value of name: {0}",
                datastore.GetItemString(lastRow, "name", DwBuffer.Primary, true));
