Built-In Aggregate Functions
The ASPxTreeList provides five built-in aggregate functions:
- Count: returns the number of records;
- Min: returns the minimum value in a column;
- Max: returns the maximum value in a column;
- Sum: calculates the sum of all values in a column;
- Average: calculates the average value of a column.
To select the required aggregate function, use the summary item’s TreeListSummaryItem.SummaryType property.
