As always thank you very much for your valuable feedback!
Optimizing our assemblies and our controls is actually ongoing task for every team here at Telerik and we are doing our best to provide smaller assemblies and lightweight controls when possible. We will continue with all these for sure however you can use the power of our products even now, without referencing undesired assemblies.
I've made for you small example using our Telerik.Windows.Data assembly and plain ItemsControl to illustrate you how to create simple data grid control with sorting support. Of course this can be extended with grouping, filtering, currency, editing, hierarchy and many more which will give even more power than ASP.NET ListView.
Please check the attached project and let me know what you think.
