Hello Saurabh,
Thank you for writing.
I am not sure that I have understood the issue correctly. I have tested a scenario similar to the described one and if you press Alt + O and then Alt + N, the "New" menu item, which is child to the "Open" is invoked. Could you please describe in greater detail what is the observed behavior in your case and which version of RadControls you are using?
I am looking forward to your reply.
Greetings,
