ASP.net ui control - JS AJAX

I found a cool control on the net that I would like to use in asp.net apps more nativley Right now it is here? ? <[login to view URL]>? I would like someone to make a .net wrapper around some javascript to make a control. I want to easily be able to bind it to a data source and be able to do the cool autocomplete like they do. the ui should be identical to this since it is a design pattern I would like you to expose some of the ui item to a css file so they are customizable if needed. Let me know your approach to making this control for me
