I'm new to CM and have some questions for the follwoing scenario:
In WP7, I have a UserControlViewModel and a PageViewModel.
The page contains the usercontrol (just assume a very simple UI scenario)
The usercontrol is just a ListBox with a header and the ListBox's Items property is bound to the UserControlViewModel's Items property.
1. Of which type should the two ViewModels be in the simplest case, ie. derived from Conductor<XY>, Screen ?
2. How should the UserControlVM and the PageVM communicate with each other ? For example, the UserControlVM needs the PageVM as source for its Items property:
=> either the UserControlVM gets an instance of the PageVM to call a method "GetAllItems()" or the PageVM gets an instance of UserControlVM to call a method "SetItems()" ?
Also a general question: should the "child" VMs know their "parents" or the other way round ?
