How to get values of grid in GXT?

Question

List<ColumnConfig<Vo, ?>> l = new ArrayList<ColumnConfig<Vo, ?>>();
    l.add(numColumn);
    l.add(subjectColumn);
    l.add(nameColumn);
    l.add(dateColumn);

    ColumnModel<Vo> cm = new ColumnModel<Vo>(l);
    Grid<Vo> grid = new Grid<Vo>(store, cm) {
        @Override
        protected void onAfterFirstAttach() {
            super.onAfterFirstAttach();

    grid.addCellClickHandler(new CellClickHandler() {

        @Override
        public void onCellClick(CellClickEvent event) {
            // TODO Auto-generated method stub

            contentPanel.clear();

GXT Grid works with data stores, more precisely it is a ListStore I think. So that, to get Values of the grid either use that store by grid.getStore(), and after that you basically have a collection of the objects in your grid (grid.getStore().getAll() return List), or you can use Grid's SelectionModel to deal with the grid selected item like this:

grid.getSelectionModel().addSelectionChangedHandler(new SelectionChangedHandler<Vo>() {

        @Override
        public void onSelectionChanged(SelectionChangedEvent<Vo> event) {
            if (grid.getSelectionModel().getSelectedItem() != null) {
                // Do whatever you want
            } else {

            }
        }
    });

I hope it will help.
