Total Summary
The total summary is the value of an aggregate function calculated over all records displayed within the ASPxVerticalGrid. Total summaries are displayed in the summary panel, provided that the ASPxVerticalGridSettings.ShowSummaryPanel option is enabled.
Total summaries are the ASPxVerticalGridSummaryItem objects. ASPxVerticalGrid stores its total summaries within the ASPxVerticalGrid.TotalSummary collection. To manage this collection at design time, you can use the ASPxVerticalGrid Designer as shown above.
To obtain a total summary value and its text representation, use the ASPxVerticalGrid.GetTotalSummaryValue and ASPxVerticalGridSummaryItem.GetTotalSummaryDisplayText methods respectively.
