Hi Friend,

Yes, you can. Try the following:

import java.awt.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.text.*;
import javax.swing.event.*;
import javax.swing.table.*;
import javax.swing.plaf.basic.*;

public class GridView extends JPanel {
RadioButtonUI ui = new RadioButtonUI();
int pageSize = 5;

Model model = new Model();
TableRowSorter<Model> sorter = new TableRowSorter<Model>(model);
Box box = Box.createHorizontalBox();
public GridView() {
super(new BorderLayout());
JTable table = new JTable(model) {
public Component prepareRenderer(TableCellRenderer tcr, int row, int column) {
Component c = super.prepareRenderer(tcr, row, column);
if(isRowSelected(row)) {
return c;
table.setIntercellSpacing(new Dimension());
showPages(10, 1);

add(new JScrollPane(table));
add(box, BorderLayout.SOUTH);
setPreferredSize(new Dimension(320, 240));
private void showPages(final int itemsPerPage, final int currentPageIndex) {
sorter.setRowFilter(filter(itemsPerPage, currentPageIndex-1));
ArrayList<JRadioButton> l = new ArrayList<JRadioButton>();

int startPageIndex = currentPageIndex-pageSize;
if(startPageIndex<=0) startPageIndex = 1;
int maxPageIndex = (model.getRowCount()/itemsPerPage)+1;
int endPageIndex = currentPageIndex+pageSize-1;
if(endPageIndex>maxPageIndex) endPageIndex = maxPageIndex;

l.add(createRadioButtons(itemsPerPage, currentPageIndex-1, "Prev"));
for(int i=startPageIndex;i<=endPageIndex;i++)
l.add(createLinks(itemsPerPage, currentPageIndex, i-1));
l.add(createRadioButtons(itemsPerPage, currentPageIndex+1, "Next"));

ButtonGroup bg = new ButtonGroup();
for(JRadioButton r:l) {
box.add(r); bg.add(r);
private JRadioButton createLinks(final int itemsPerPage, final int current, final int target) {
JRadioButton radio = new JRadioButton(""+(target+1)) {
protected void fireStateChanged() {
ButtonModel model = getModel();
if(!model.isEnabled()) {
}else if(model.isPressed() && model.isArmed()) {
}else if(model.isSelected()) {
if(target+1==current) {
radio.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
showPages(itemsPerPage, target+1);
return radio;
