Have you done some testing with real data to determine if server paging is warranted?  In my experience, data access is extremely fast.  It is the rendering of large datasets that is usually the bottleneck (though much faster since 8.5).  You can speed up data transfer by compressing the data.  I haven’t done this yet, but others have.

 

I know I would seriously doubt the value of server paging for a 400 / 25 record situation.  4000 / 250 maybe, 40,000 certainly.  That is just based on experience, no rigorous testing.

 

If you do page, clearly you can’t return a subset of a sorted set without sorting the whole set.  That will have to happen on the server, so any sort is a server hit.  One more count against paging.

 

I am just thinking, perhaps someone with some direct experience will be more help.

Subject: [flexcoders] Sorting data grid that has paging.

 

We have an issue we are trying to resolve. We know that the datagrid by default has the
ability to sort. But this only works when all potential results are downloaded into the
datagrid from the server. ex. User does a search that returns 425 results. We want to use a
paging concept to limit results to say 25 records. The sort needs to sort on all 425, not just
the 25 visible in the grid. Is there anythign in place or do we need to custom build
something? Has anyone seen a component that does this? Thanks.
