Autocomplete Search Component for TextBoxes in ASP.NET

I'd like to use a component similar to the Tags autocomplete com开发者_运维百科ponent used by Stack Overflow in my ASP.NET 2.0 application. What can I use?

It uses JQuery Autocomplete. If you want something like it, you can use the Ajax Control toolkit's Autocomplete.

You can't get there with just a serverside component alone; you'll have to use JavaScript or JQuery to make it work.
