Remarks

The Tree List allows you to display concise information about the children of nodes. For example, you can display the number of records, or maximum value, etc. This is called a summary.

The Tree List stores its total summary items within the DevExpress.Xpf.Grid.TreeListControl.TotalSummary collection. Node summary items are stored within the TreeListNodeSummaryItemCollection collection. Individual summary items are represented by the TreeListSummaryItem class.
