Hello Jan Pfeffer,
Thank you for contacting us.
Our controls are designed to operate in a managed environment as a standalone application. We have not tested our controls for compatibility with the mentioned programs. Please note that we do not support COM officially and you may experience issues when using our controls in this scenario.
Nevertheless, could you please send us your project and describe how to reproduce these issues. We will investigate the case and we will try to find a proper solution.
I am looking forward to your reply.
the Telerik team
