Im trying to learn MVVM so far its going well , I have stumble on a situation which I don’t know how to implement ..

What I want :
– A view with left navigation and right details pane .. right details will have a contentcontainer which would hold my User Controls for the views to be selected by left pane

What I have :
– A MainViewModel
– ViewModels for Each of the Entities I have on my database

My Problem :
– Since I will have an ObservableCollection of my VIEWMODELS in my MAINVIEWMODEL ( as per the example i’m patterning my application ) do I create a public property for each of my MODEL Entities which will be used for the databinding I have defined in my UserControls ??

    You can create a Base Type for all of your ViewModels to be displayed on the right side.(lets call that as BaseContentViewModel)
    Then your left side ListBox will be bind to ObservableCollection<BaseContentViewModel> and the SelectedValue of the ListBox will bind to a new MainViewModel.SelectedContent proeprty of Type BaseContentViewModel.

    And on the right side you need to have a ContentControl to which SelectedContent bind to ContentControl.Content

    Now it is just a matter of defining different UserControls as DataTemplates in the Resource XAMLs (Usually refers as ViewToViewModelMapping in MVVM)
