Property Value

TcxDataSummaryGroups

Remarks

The SummaryGroups property allows you to access summary groups. Use the SummaryGroups property to associate group summaries with specific grouping items. These summaries are calculated when data is grouped by these items. You can assign any grouping item to a set of group summaries. Moreover, you can assign the same set of group summaries to several grouping items.

DefaultGroupSummaryItems also defines the collection of group summaries. It specifies summaries calculated when you group by any item that is not referenced by SummaryGroups.

You can use the GroupSummaryItems property to access the collection of group summaries at the specific level disregarding whether they are provided by the DefaultGroupSummaryItems or SummaryGroups property.

Use the GroupSummaryValues and GroupSummaryDisplayValues properties to get a value of an individual group summary or to set it manually. You can do this, for instance, in the OnAfterSummary event which occurs after all summaries have been calculated.

To return formatted text representations of summary values use GroupFooterSummaryTexts and GroupSummaryText.
