Aggregates
The TreeList enables you to display aggregated number results when the user groups its data.
To enable grouping with aggregate functions, use the DataSource.Aggregates()
, ClientGroupFooterTemplate()
, ClientGroupHeaderColumnTemplate()
, or ClientFooterTemplate()
methods of the TreeList, and the aggregate
fields of its data source. For a runnable example, refer to the demo on using aggregate functions in the TreeList.
