- ## Method Details

  - ### addDataArrivedHandler

    HandlerRegistration addDataArrivedHandler(DataArrivedHandler handler)
    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:
      `handler` - the dataArrived handler
    Returns:
      `HandlerRegistration` used to remove this handler
