On the client side, you would use mx.data.DataService or you can just use the RemoteObject tag. You can read more about it here: http://www.themidnightcoders.com/articles/datamanagement-part2.htm cheers, Joe --- In [email protected], "Kelly Birr" <[EMAIL PROTECTED]> wrote: > > Dmitry, > > I've done it from ASP.NET to Flex 2.0 without FDS by caching the Datasets in > memory on the Application Server and sending pages to the UI as requested. > It works very well but it uses a lot of memory and CPU time on the mid-tier > servers and took a bit of code for the server-side threading requirements. > It may be worth trying FDS to save yourself the hassles of this sort > of implementation. > > My approach was: > > 1) Flex UI calls Web Service on server to request the list (dataset). > a) Server spins up background worker thread for list building > b) Server queries database and begins filling dataset on worker > thread > c) primary [request] thread waits for one full page of data to be > filled > > 2) Once server has filled one full page of data it sends the response to the > client with the first page and a unique "PagingContextID" (guid).
