MVVM using Page Navigation On Windows Mobile 7
- by anon
The Navigation framework in Windows Mobile 7 is a cut down version of what is in Silverlight. You can only navigate to a Uri and not pass in a view. Since the NavigationService is tied to the View, how do people get this to fit into MVVM. For example:
public class ViewModel : IViewModel
{
private IUnityContainer container;
private IView view;
public ViewModel(IUnityContainer container, IView view)
{
this.container = container;
this.view = view;
}
public ICommand GoToNextPageCommand { get { ... } }
public IView { get { return this.view; } }
public void GoToNextPage()
{
// What do I put here.
}
}
public class View : PhoneApplicationPage, IView
{
...
public void SetModel(IViewModel model) { ... }
}
I am using the Unity IOC container. I have to resolve my view model first and then use the View property to get hold of the view and then show it. However using the NavigationService, I have to pass in a view Uri. There is no way for me to create the view model first. Is there a way to get around this.
