          com.google.gwt.event.shared.HandlerRegistration addDataArrivedHandler(DataArrivedHandler handler)

      Notification method fired when new data arrives from the `DataSource` to be displayed in this ListGrid, (for example in response to the user scrolling a new set of rows into view). Only applies to databound listGrids where the `data` attribute is a `ResultSet`. This ResultSet may have been created manually and applied to the grid via a call to `setData()` or may have been created and automatically assigned if `fetchData()` was used to populate the grid. This method is fired directly in response to `dataArrived()` firing on the data object.

      Note that `dataArrived()`, unlike `ListGrid.dataChanged()`, only fires in limited circumstances - when data for a `ResultSet` arrives from the DataSource due to a fetch or cache invalidation, or as a result of `filtering`. If you want to catch all data changes, you should instead react to `ListGrid.dataChanged()`.

      Parameters:
        `handler` - the dataArrived handler
      Returns:
        `HandlerRegistration` used to remove this handler
