            If I were to guess, I'd say it's a highly customized YUI DataTable, so that might be worth checking out.

            And if you are looking for ASP.NET AJAX grid solution with yahoo-like scrolling, the Telerik grid may give you Yahoo-like deferred scrolling. Check out this demo on their site.

            DHX's dhtmlxGrid control will do that as well. The basic edition is free.
They've got examples with 50,000 records, with and without paging.
