Ajax autocomplete extender populated from SQL -

-

ok, first let me state have never used control , first attempt @ using web service.

my dilemma follows. need query database column , use autocomplete. don't want query run every time user types word in textbox, best guess run query once use dataset, array, list or whatever filter autocomplete extender...

i kinda lost suggestions??

why not keep track of query executed user in session variable, use filter further results?

the trick preventing database overloading think limit how auto updater allowed update, once per 2 seconds seems reasonable me.

what this: store current list returned query word server side , tie session variable. should entire list think. then, each new word typed, long original word exists, can filter session info , spit filtered results out without having query again. basically, query again when word changes.

i'm using "session" in php sense, may using different language different terminology, concept should same.
