I had in mind where the visible condition is based on the content of 1 or more

only that one view, I would still use code in the VM to evaluate the current
record!


That is what I showed in my more complex example. The multi-converter takes in 4 values and returns a decision based on those 4 values. I only showed you a small portion of that trigger, but there are actually 5 cases "1", "2", "3", "4", "5".

The problem with your solution is that you may leave holes where you update one of the values used in the calculation but forget the OnPropertyChanged("VisibilityForState1"); call.

I have done it your way in the past, but found that I didn't like having to put OnPropertyChanged() calls for 4 or 5 properties all over the place.

Also, I kind of believe that the VM should strictly be for communication between the V and M. Adding a bunch of properties to support the view couples them more closely then they should be.
