TcxDataSummaryItems Class

Represents a collection of summaries.

Declaration

TcxDataSummaryItems = class(
    TcxCollection
)

Remarks

TcxDataSummaryItems is a collection of single summaries, each of which is represented by the TcxDataSummaryItem class. The TcxDataSummaryItem object associates an item with the summary type (sum, average, maximum, etc.). Use the Items property to access an individual summary.

The TcxDataFooterSummaryItems and TcxDataGroupSummaryItems classes are derived from TcxDataSummaryItems. They implement group summaries and footer summaries respectively. Use the TcxCustomDataController.Summary property in order to set both group summaries and footer summaries for your grid.

The OnSummary event allows you to change the default behavior of summary calculation. Use this event when you want to exclude specific values from the summary result or replace individual element values with another ones.
