Specifies how a group footer is positioned with respect to its group in a report.
A group is printed so that it is split across several pages if there isn’t enough space on a page to print the entire group.
A group is split across several pages “as is”. However, if there are no group rows printed above the Group Footer on a page, the last group row from the previous page is moved to the next page, and is printed before a Group Footer, so that a Group Footer is never printed on a page alone (with no group rows above it).
Use this enumeration’s members to specify if a group footer can be printed on its own on a page, or if it should always be printed with at least one group detail row. The values listed in this enumeration are used by the GroupFooterBand.GroupUnion property.
