- - ### Method Detail

    - #### onGroupByComplete

          void onGroupByComplete(GroupByCompleteEvent event)

      Callback fired when the listGrid is grouped or ungrouped.

      Unlike `ListGrid.groupBy()`, this notification will fire when grouping is complete, and the `data` object has been updated. On successful grouping the `fields` argument will list the new grouping and the `groupTree` will have been updated to reflect the grouped data.

      Note that the `fields` argument may be an empty array if the data is not grouped. This implies that a user or developer explicitly ungrouped the grid, or that a groupBy attempt failed due to the data length exceeding `groupByMaxRecords`.

      Parameters:
        `event` - the event
