Footer Summaries

Footer summaries represent summaries that are calculated against all nodes and displayed within footer cells. They are specified via a column’s Summary.FooterSummaryItems collection.

You can use built-in functions or manually calculate summary values by handling the TreeList control’s OnSummary event. You can opt to include all nodes for the calculation base or calculate using only the root level nodes. End-users can specify the required summary types and adjust summary options via the footer context menu.
