NoScrollGrid Flow Addon | Vaadin

Extension for Grid to delegate vertical scrolling outside the Grid's scroll container

NoScrollGrid Extension for Grid

NoScrollGrid itself will never show vertical scroll bar. Scrolling down to bottom of the target scroll container (or optionally mouse wheel down/touchmove event) will increase grid's height automatically by predefined number of rows.
Grid's data provider defines the maximum size Grid can grow. Higher the Grid is set initially or by scrolling, more rows are being fetched and cached in client.


Quick sample how to use NoScrollGrid. NoScrollGrid extends Grid, so it works like Grid for most parts.

NoScrollGrid<Item> grid = new NoScrollGrid<>();

getElement() in this sample return a com.vaadin.flow.dom.Element which can be <body>. Or it can be any other element like <div> as long as it is vertically scrollable ("overflow: auto;" for example). Given element should be ancestor for NoScrollGrid element in DOM hierarchy.

To change number of items to show more, you can call setRowsShownMoreOnScrollToBottom(int) explicitly. NoScrollGrid calls this method in constructor already and sets it to same as Grid's page size.

NoScrollGrid<Item> grid = new NoScrollGrid<>(20);

Grid's page size affects the number of rows browser requests from the data provider and NoScrollGrid uses it to define size of the buffer for requested rows. Real number of rows requested and cached to client is usually number of rows that fit in NoScrollGrid's height plus buffer size.

Override NoScrollGrid.showMoreOnInit to false (default is true) to hide scroll bar initially.
