Remarks
The grid calculates a summary for each group and displays it within the group header (group row). Use the GetGroupSummaryValue
method to obtain a summary value for a specific group.
GridColumnSummary objects specify a data field, aggregate function, and a format for the display of a summary. The DataGridView stores these objects in the GroupSummaries collection.
