Type Description

An object that represents the specified summary value.


A summary value can be displayed within footer cells and group footer cells. The node parameter represents a parent node, which identifies a group of nodes whose values are used to calculate a summary value. If this parameter represents a node contained within the ASPxTreeList.Nodes collection, the GetSummaryValue returns the summary value (total summary) displayed within a footer cell.

If the node parameter represents a parent node residing at the lower nesting level, the GetSummaryValue method returns a summary value displayed within the corresponding group footer cell.

The GetSummaryValue method returns a null reference, if the specified node isn’t contained within the ASPxTreeList.Nodes collection, and has no children.
