Hi,

I downloaded an example from below URL

I am confused about how views are getting loded when the ContentControl is bound to ViewModel in ApplicationView.xaml in this example. Nowhere in the code Views as associated with ViewModel.

Can someone please explain me about this?

Perhaps you missed this in the "Views" section, "This allows me to use DataTemplates to tell WPF how to draw each IPageViewModel".

Thanks Phantom, you are right. I really missed DataTemplates. Thanks for the answer.

Why not asking Rachel about it? I would not take any responsibility for explaining her view on this.

If you define a DataTemplate in your Resources that has a DataType property but not a Key property, it is considered an Implicit DataTemplate. This means, it will be used anytime WPF tries to render an object of the specified DataType.

My example has DataTemplates without a Key property defined for each of the ViewModels, so when WPF tries to render the ViewModel into the ContentControl.Content area, it uses the specified DataTemplate instead =)
