Which property do you enable to keep rows in a break together on the same page?

The 'Start on New Page' property in the Format Section forces a section to always begin on a new page rather than preventing rows from being split across pages.

The generic 'Start on New Page' property forces a new page at the start of each element but does not prevent mid-block page breaks from splitting rows within a break.

The 'Avoid page breaks in block' property, found in the block's layout or format properties, instructs the rendering engine to keep all rows belonging to a break section together on a single page. When enabled, if the rows do not fit on the current page, the entire break group is moved to the next page rather than being split mid-block.

There is no standard Web Intelligence property named 'Avoid page break' located specifically in the Format Section; the correct property name is 'Avoid page breaks in block' and it is a block-level property.
