Re: Dynamic filtering of record sets

Thanks, guys.

Pratik, there are several places in the web application I am
evaluating where this sort of filtering is used. For instance, in the
application, the user creates a number of pages, each with a unique
title. There is a central place where the titles of all these pages
is listed and these titles are links to each specific page. At the
top of the list is a filter field where the user can enter in a
string. As each letter is typed, the string is compared against the
titles of all the pages and ones that don't contain the string are
removed from the list.

Bryan, this is what I was thinking of. I just wasn't sure if this was
the best strategy or if there was another, better, way that I hadn't
thought of.

Best,
Rob

For instance, you have a field and as you type each character, a set of records below it are updated. This is not intended to be an auto-complete or a combo box type thing, since the list of items updated is separate from the field.
