Ted Patrick has collected a handful of nifty live data filtering UI examples. Live data filtering provides search results on the fly as you alter search parameters. The search parameters could be either search text, price, criteria and such. If the result set is generally small and fast, it eliminates the need of clicking the search button.

Ted’s samples are all Flex based. For archival purpose, I replicate his collections here, as well as a few non-Flex ones.
