Thank you for the feedback. There really seems to be a problem with the CanExecute inside a RibbonView and I logged it in our PITS
under the name "CanExecute doesn't work correctly inside collapsed RadRibbonTabs"
and it'll be ready for voting and tracking tomorrow the latest. I hope that this bug will be fixed for our next internal build or the upcoming Service Pack.
For now I was able to find one workaround - handle the loaded event of your RadRibbonGroup and invalidate the command there.
I've attached a sample project and if you have further questions please feel free to ask.
All the best,
the Telerik team
