Developer Guide

Getting started

Every extension has it's own API that you can read from the classes. TableSelectionModel is (as the name indicates) a SelectionModel. Use it like this

TableSelectionModel model = new TableSelectionModel();

Using the PagedDataProvider:

// This is your existing data
PagedDataProvider<?> dataProvider = new PagedDataProvider<>(
Grid grid = new Grid();

// PagedDataProvider has a helper class for page manipulation
PagingControls controls = container.setGrid(grid);

// Set grid to certain size

// Jump to fourth page (0-based indexing)

// Jump to next (fifth) page

For a more comprehensive example, see in GridExtensionPack-demo



TableSelectionModel gives you client-side selection UX similar to Table. It supports Multiple selection in simple mode and with ctrl + click.


A simple data provider wrap. Works through paging and provides its own PagingControls for a cleaner API.

This does not work with Table.

PagedContainer (Vaadin 7.x only)

A simple Container wrap on top of any indexed container. Works through paging and provides its own PagingControls for a cleaner API.

This also works with Table, but I don't intend to track any possible issues with it.


This extension provides a way to add custom items in the Grids SidebarMenu. Setting styles and custom captions along with running certain code when the menu item is clicked, this is the easiest way to get your special actions in to said menu.


This extension makes possible to wrap text in headers. Sometimes you need long header description in columns where the data content is short (e.g. number). With this extension you can enable wrapping text in header row and it auto adjusts the header row height accordingly.


A simple helper extension that gives you an API that you can use to force the repaint of a row.


This extensions provides an easy way to configure a custom cache strategy for Grid client-side. It uses an int value and a double value with a simple equation to count the limits. See class JavaDoc for example values
