Perfectly possible using just javascript. Its just an absolutely positioned div filled with some text depending on the validation error.
You'll need to have server side validation though which will display errors if the user has javascript disabled though.

The site is using the AjaxControlToolkit for ASP.NET.
For the validation the site use the ValidatorCallout. Have a look here : http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ValidatorCallout/ValidatorCallout.aspx

The AjaxControlToolkit can be downloaded from this site : http://www.asp.net/AJAX/AjaxControlToolkit/

Sorry AlbertVanHalen I read it as .Net 3.0, but to be fair this is in the ASP.Net & .Net Zones.
You might want to have a look for code in Dynamic Drive, it's where I used to go for stuff like this when I was writing classic asp pages.
