Remarks

DataGridView stores group summaries in the GroupSummaries collection. An individual summary is a GridColumnSummary object. The grid calculates a group summary for each data group and displays each group summary value within the corresponding group row. Use the GetGroupSummaryValue property to obtain a summary value calculated for the specified group.
