I understand your issue, but the solution with RadMenu
is rather a workaround, achieved by faking the desired behavior. It will only work when the menu has the same back color as the scroll panel due to the specific behavior of RadMenu
when it is docked or anchored.
Feel free to ask if you have any other questions.
