textbox autocomplete
===

how do i make an autocomplete textbox in asp?
but i need to get the autocomplete data by querying the database. 
I dont really know how to explain this, sory if theres not enough detail. 
i cant use ajax, because i think i will have compability issues with my old app.
so im thinking of doing this using java script. or is there a way to do this by using .net?
im using C# for codebehind. thanks
