Thank you for your feedback. With the release ofUI for Windows Universal - we introduced DataBoundListBox control built for WinRT framework. With the new framework there are many improvements, however, it has its limitations. One of them is the lack of built-in pull-to-refresh gesture recognized by the framework. Thus, we are working on implementing the same behavior and API as with the Silverlight stack.
I have logged your feedback as bug report and will do our best to provide the same behavior as with WP8.0.
Also, thank you for your suggestions regarding the documentation and examples. Currently, we are working on improving them.
You can find our documentation for UI for Windows Universal here - http://www.telerik.com/help/windows-8-xaml/radcontrolsforwin8-introduction-overview.html
P.S. I have update your telerik points accordingly.
