DataTable - Instant Row Selection

Instant row selection feature processes a selection with ajax when a row is selected. If defined a rowSelectListener or rowUnselectListener is invoked passing row data as parameter, optionally other components on page can be updated with onRowSelectUpdate/onRowUnselectUpdate options. onRowSelectStart and onRowSelectComplete are additional client side callbacks for further customization. Note that rowSelectListener is aware of JSF Navigations so by returning an outcome you can navigate to another page with the selected row information.
