ASP.NET AJAX Textbox to DataList/Grid

I'm looking to create a free-type textbox which onkeyout "filters" a datagrid below. The old way to do this was to write a webservice and call it on each press returning the r开发者_StackOverflow中文版esults - I was hoping there was a more eloquent way of doing this. Can anyone point me in the right direction? Documentation/Tutorials/Sites etc all welcomed.

Sorry for the very noob question!

You might have luck in find an answer in this Stackoverflow question:

Filtering a list as you type with jQuery.

Or possibly with this Stackoverflow question:

vb.net dataTable/DataGridView search/sort

Hope this helps some.
