Progressive scroll paging is very similar to scroll paging in that additional rows are added to the Interactive Grid. The difference is that when the total number of rows is not known it is not possible to set the height of the virtual scrolling area. New rows are added as the user scrolls to the end. It is not possible to jump to the end of the result set and scroll backwards. To use progressive scroll paging set the Pagination: Type to Scroll and Show Total Row Count to No. Note that progressive scroll paging applies to Icon and Details views as well.
