Re: How to present large datasets on the Web?

> Why?  Why not provide a page at a time?  This seems wasteful...
Users request. They found it to be much slower for them to click & re-load
next page or previous page. In this app users doing property searches
based on various search criteria. I wouldn't do this for just any app, but
I think user requirements should definitely be considered. In my case, there
may be many records (normally too many for one page) related to a single
search request, and using the slide bar, the user could quickly visually
review
all before making a selection.
If you are concerned about the processor requirement, think of a single user
clicking 100 times for next page, versus one large load?
I don't think there is a general rule to fit all apps.
