Windows Phone 8.1 navigate using string instead of a type

Question

In Windows Phone 8.1 there is any way to navigate from one page to another using an string instead of a Type?

There is no reflection and Frame.Navigate only accepts type.

Thank you.

Most people write a NavigationService that wraps the frame navigation an looks up page names in a dictionary. You will still have to register the types somewhere. – Bencion

What do you mean, there is no reflection? – Septuplet

any problem with types? – Orvilleorwell

@KaiBrummund Nice idea, the best is do a dictionary! :-) – Prostatitis

@BlackCid Having a NavigationService ot some sort is generally a good idea, and you should go for it. I'm pretty sure you can also use Reflection, though, if you need to. – Septuplet

Answer 1

I agree with Kai Brummund. You should write a NavigationService. A good example of a navigation service is the MVVM light navigation service. Here you can find the source code.

Or... you just can use MVVMLight which comes with an integrated NavigationService (INavigationService). You set it in ViewModelLocator like this:

private const string URL_DETALLE = "/View/DetalleView.xaml";
public ViewModelLocator()
{
    // ...

    var navigationService = this.CreateNavigationService();

    if (!SimpleIoc.Default.IsRegistered<INavigationService>())
    {
        SimpleIoc.Default.Register<INavigationService>(() => navigationService);
    }

    //...
}   

private INavigationService CreateNavigationService()
{
    var navigationService = new NavigationService();
    navigationService.Configure(URL_DETALLE, typeof(DetalleView));

    return navigationService;
}

Then in your VM constructor you will recieve this navigaton service and you can use it this way:

private INavigationService navigationService;
public DetalleViewModel(INavigationService navigationService)
{
    this.navigationService = navigationService;
    this.navigationService.NavigateTo(ViewModelLocator.URL_DETALLE);
}

Hope it helps ;)
