Declaration

TcxDataSummaryGroups = class(
    TcxCollection
)

Remarks

The TcxDataSummaryGroups class represents a collection of the so called summary groups. A summary group is an association of specific grouping items with group summaries. When data in a grid control is grouped by any of the grouping items, relevant group summaries are calculated.

The Items property provides the indexed access to individual summary groups. Each summary group is maintained by a separate TcxDataSummaryGroup object.

The main class, which calculates all grid summaries, is TcxDataSummary. Both the TcxDataSummary.SummaryGroups and TcxDataSummary.DefaultGroupSummaryItems properties support group summaries. The TcxDataSummary.DefaultGroupSummaryItems property defines the default group summaries when grouping by any item. You can redefine group summaries for specific items via the TcxDataSummary.SummaryGroups property.
