How to add/use an AJAX control in a non-AJAX enabled website in ASP.NET?

I have started a simple website using ASP.NET but it is not an AJAX-enabled project. Now what I need is to use an AJAX control (specifically Autocomplete) but I do not know how to add it to my website. What I should do guys? Do I need to add something in my library?

What should I do in order to see it in the toolbox..?

Please help me I'm just a newbie.开发者_StackOverflow中文版..

Thanks in advance...

Well unless you use ajaxcontroltoolkit, you cant use asp.net ajax autocomplete. I suggest you use some other javascript library and use its autocomplete feature. jQuery and Mootoold (my fav) both have autocomplete plugins
