showInColumn
Type: GridColumn
A GridColumn object (or descendant) specifying the column whose footer cells should display summary values. null (Nothing in Visual Basic) to display summary values within group rows. This value initializes the created item's GridGroupSummaryItem.ShowInGroupColumnFooter property.

Expanded Remarks

If you need to add several group summary items to the collection, consider using the GridSummaryItemCollection.BeginUpdate and GridSummaryItemCollection.EndUpdate methods to prevent the collection from being updated until all required items have been added. Alternatively, you can use the GridSummaryItemCollection.AddRange method, which adds the specified summary items array.

To remove a summary item from the collection, use the GridSummaryItemCollection.Remove method.
