The ASPxTreeList enables you to manually implement custom aggregate functions or calculate
summary values using a custom algorithm. Custom summaries allow you the following:
- Calculate summaries against nodes that meet specific criteria
- Involve multiple data fields in calculations
- Implement complex summary functions
To manually calculate summaries, you should set the summary item's SummaryType property to Custom
and handle the CustomSummaryCalculate event.
In this demo, we sum the budget of selected departments.
