For example, let's say I have a "User" model with a findByName() method. The ViewModel would call this in order to pass the relevant user details to the view. The model would likel...
I have lots of nested controls in the panel and I want to disable all of them, but leave scrolls enabled. Basically, I'm setting IsEnabled property of the root element (panel) to false using binding.
