Question

I am making a Winodws Phone 7 program, I’ve got another question. So, my question concerns, how would I bring in two classes using one datacontext? My code currently looks like:

    public MainPage()
    {
        InitializeComponent();

        DataContext = App.ViewModel;
    }

Now, what I want to do is add another Model:

    public MainPage()
    {
        InitializeComponent();

        DataContext = App.ViewModel, App.ViewModel2;
    }

But that doesn’t seem to work.

How would I make it to where I can have two objects in one form?

This is a silverlight / Windows Phone 7 application.

I need to have 2 modules loaded as one is for Accounts and the other is for Buddies, and I don’t want 10 different pages as it’d look nicer with just one page for all the normal things.

Thanks.

You will need an object that contains both.

DataContext = new { VM1 = App.ViewModel, VM2 = App.ViewModel2 }

I would not use an anonymous type, just an example, since you want support for INotifyPropertyChanged. Basically you are looking for composition.
