title: textbox autocomplete
body: <p>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</p>
