I think so too, theorically. OTOH, there are some work-intensive grids, that are based on chunks of data from big tables, where the requery takes a long time, and this can be sometimes inacceptable.

>>I agree with you if you try to exclusively set filter to a big table, but not if you use set key beforehand. I have an application where a grid browses a table ( 300k records ) directly. I first use set key for the first subset to be shown ( that's where set filter shows very slow performance ), but then i activate any filter condition i want, and it's very fast!
