Thank you for writing.
Currently, RadControls for Winforms do not support inheriting the standard Windows themes. We will add it in some of the feature release, but I cannot give you a time-frame because this is a big task and we should consider its development. Nevertheless, you could use our themeing mechanism to create your custom themes and implement a great look and feel for your application.
If you have other questions, do not hesitate to contact me again.
