Obviously you are struggling with dynamic creation of RadDocks, so I believe it will be easier for us to help you if you could isolate the problematic scenario in a simple running project
that you will send us so we can review it and provide assistance. I am attaching instructions how you can open a support ticket where you can attach files. Furthermore, please provide detailed information on what you expect to happen and what actually happens - I need to know what you try to achieve to be able to offer suggestions for modifications of your code. looking forward to your answer.
