Hi Roberto,

We made some changes in IsEnabled property - when you set it to False then RadMenuItem will be disabled no matter what ICommand CanExecute return. But if IsEnabled is True then IsEnabled actual value will be based on ICommand CanExecute result. That is why probably we clear your binding.
Please specify Binding Mode=TwoWay so that Binding will not be removed internally.

Let us know if this works for you.

Kind regards,
Hristo
