Hello ,

It seems that your demo project failed to attach. Could you resend it so we can investigate the behavior mentioned in your post on our side?

Thank you for your cooperation.

Hello ,

We weren't able to reproduce the described behavior. We have tested it on several different machines with different OS systems (Win10, Win 8.1, Win 7) with no success. 

As a side note, it sounds very strange that PreviewKeyDown event is called when RadDiagramShape is dragged. You can double check your code if there could be any other reason causing this behavior. We have attached to this reply the sample project which we were using to test your scenario. You can check it if we are missing something.

We are looking forward to your answer.
