- - ### Method Detail

    - #### onDataArrived

          void onDataArrived(DataArrivedEvent event)

      Notification method fired whenever this TreeGrid receives new data nodes from the dataSource. Only applies to databound TreeGrids where `data` is a `ResultTree` - either explicitly created and applied via `setData()` or automatically generated via a `fetchData()` call.

      Note that `dataArrived()`, unlike `TreeGrid.dataChanged()`, only fires in limited circumstances - when data for a `ResultTree` arrives from the server 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 `TreeGrid.dataChanged()`.

      Parameters:
        `event` - the event
