TcxGridTableSummaryItem Class

An object representing a single summary to calculate for a specific column.

Declaration

TcxGridTableSummaryItem = class(
    TcxDataSummaryItem,
    IcxStoredObject,
    IcxGridSummaryItem
)

Remarks

ExpressQuantumGrid allows you to calculate different summaries using the View’s DataController.Summary property. The Summary object provides the FooterSummaryItems, DefaultGroupSummaryItems and SummaryGroups properties and these specify the collections of footer summaries, group summaries and summary groups respectively.

Individual summaries within these collections are represented by TcxDataSummaryItem class objects. When creating summaries in tabular Views, the TcxGridTableSummaryItem class is used instead of TcxDataSummaryItem. In addition to the settings inherited from the base TcxDataSummaryItem class, the TcxGridTableSummaryItem class introduces members that allow you to specify:

the column for which the summary is calculated (Column);
the visibility and the caption for the Group Row Popup Menu item associated with the summary (VisibleForCustomization and DisplayText).
