restrictions can be largely hidden from the end user as AJAX can send back to the server
those cells that have changed and updating only those calculations that need recalculating.
For paging, only those rows that are displayed need to be fetched from the server.
FarPoint introduced support for AJAX in Spread for Web Forms in version 2.5. With
Boolean properties on the FpSpread component class, Spread for Web Forms can be made
aware that the application is using AJAX. See the product tour at our web site or available
with the product download: http://www.fpoint.com/netproducts/spreadweb/tour/AJAX.
The example from that product tour, with a custom toolbar to allow user interactivity,
briefly described here to show how AJAX can improve a spreadsheet application.
