There is not too much for debugging in my code. Please see the code I provided above - it is a fully functional code using only Radzen components which easily reproduces the problem.
I would also attach the visual studio project file with the code above (which could be easily compiled and executed) but as a new user of this group I am getting a message I am not allowed to do uploads 
The infinite loop involves two methods: OnRowSelected and the data query ViewModel.Patients.
(Again strange is the infinite loop occurs even if that OnRowSelected callback is empty. If that callback is not specified the infinite loop does not occur. And also this occurs only if one of tabs is enclosed by AuthorizeView.)
Would it be possible for you to investigate that issue and provide a solution/advise?
(May I send/upload that very simple visual studio project file?)
