Group Summary

  • 2 minutes to read

The group summary represents the value of the aggregate function calculated over all data rows within a group. Group summaries are displayed within group rows or group footer cells.

BootstrapGrid_GroupSummary

Group summaries are represented by the ASPxSummaryItem objects. Bootstrap Grid View stores its group summaries within the ASPxGridView.GroupSummary collection. To manage this collection at design time, you can use the Edit Form as shown above.

The ASPxSummaryItem object provides two properties allowing you to determine the location to display the summary.

To obtain group summary values, use the following methods.

Method Description
ASPxGridView.GetGroupRowSummaryText Returns the summary text displayed within the specified group row.
ASPxGridView.GetGroupSummaryValue Returns a summary value calculated against the specified group of rows.
ASPxSummaryItem.GetGroupRowDisplayText Formats the specified value according to the current group row summary item's format settings.
ASPxGridViewSettings.ShowGroupFooter Specifies the ASPxGridView group footers visibility.
ASPxSummaryItem.GetGroupFooterDisplayText Formats the specified value according to the current total summary item's format settings, when the summary is displayed within group row footers.
