I'm afraid that currently, ASP.NET 4.0 does not include the client-side templates as they have been pushed to ajax script library (part of Ajax Control Toolkit).
From this blog post
, it seems that MS will not invest in their own templates but encourage people to use of jQuery's templates instead. Therefore we currently does not have plans to immediately include built-in support for asp templates, but more likely will consider providing demos of how to use them with some of RadControls for ASP.NET AJAX. A basic implementation of RadListView's client-binding can be found in this blog post
