Data for cells are fetched lazily on demand from server. InfiniteGrid is not extending or using Vaadin Grid and does not share features like resizable columns or row selection. It is aimed to provide a way to have an arbitrary number of columns without a performance penalty having elements outside visible scope. In practice the max scrollable area depends on browser limitations.

Sample code

InfiniteGrid infiniteGrid = new InfiniteGrid();
infiniteGrid.setCellSize(200, 40);
infiniteGrid.setItemCount(100000, 100000);
infiniteGrid.setTextOnly(true);
infiniteGrid.setHtmlGenerator((x,y)-> String.format("%d, %d", x,y));

InfiniteGrid infiniteGrid = new InfiniteGrid();
infiniteGrid.setCellSize(200, 40);
infiniteGrid.setItemCount(100000, 100000);
infiniteGrid.setComponentGenerator((x, y) ->
        new Button(
            String.format("%d, %d", x, y),
            e -> Notification.show(String.format("clicked (%d, %d)", x, y))
        ));
