The Group and Field objects also have KeepTogether properties.

The Group object's Group.KeepTogether property works across sections. It determines whether group headers should be kept together with their first detail section or whether entire groups should be kept together on a page.

The Field object's Field.KeepTogether property determines whether the field should be rendered on a single page or whether it is allowed to be split across page breaks.
