How do I switch views in a WPF application using Unity and MVVM?

I am very new to WPF and am trying to set up an application that requires switching of views.

For example, a user is viewing a system that contains a number of components, when they click on a component, it should switch to a view that is associated to that component, replacing the previous system view. It's my understanding 开发者_StackOverflowa Controller should be used here but the implementation eludes me.

I have found a few examples, but the projects are a bit too large for me to actually follow what is going on specifically with the view switching. What would really help me here is some example code from the Unity setup in the App file that allows multiple views, the Code in the controller that switches the view, and the code associated with a button that makes the controller switch the view.

Thanks

If you are just beginning with WPF and diving directly into using IoC/MVVM, then you may want to consider taking a step back and starting with the WPF fundamentals, i.e., layouts, routed events, commanding, binding, dependency properties, INotifyPropertyChanged, etc...

To get you started: tutorials on wpf and mvvm.

For most of us mere mortals, WPF has a steep learning curve. Yet, once you make it over that first hump, the 'aha moments' start kicking in on a regular basis.

I'm using Mvvm-Light, but I believe Unity will be similar.

You should have a ViewModelLocator where you register ViewModels.

You should have somewhere styles or datatemplates that tell the framework what view to show depending on the view model encountered.

You should have some property you bind to, that is a base view model.

From there, all you'll have to do is change that property to a different view model, and your view will update accordingly.

As Metro said, steep learning curve, but once you get used to it, it starts to make sense :)
