View which manages some generic variable object with Prism

Question

I'm working with Prism and I have a view which will manage some variable entity objects.

E.g.: Now I'm managing a User, but later I would manage a Customer using the same view (I already have the solution to achieve it ... link 1 - link 2).

This object (or the object type) to be managed must be declared and passed by me.

In a common way, I could pass the object type through a parameter on the constructor, but as I'm using Prism and I don't directly use the constructor of the Views or ViewModels.

Here's a snippet of how I currently "invoke" my views:

var regionManager = ServiceLocator.Current.GetInstance<IRegionManager>(); var viewUri = new Uri("MyGenericView", UriKind.Relative); regionManager.RequestNavigate("AreaTrabalho", viewUri);

The problem is: I can't pass a parameter. Is there a way of passing that parameter or an alternative way of doing this (without a kind of ugly hack)?

You can implement INavigationAware on your VM's and pass parameters inside query string in your regionManager.RequestNavigate call

Implementing INavigationAware on my ViewModels didn't work for me. It only worked when implemented on the Views. And as far as I know, I can only pass string through a query string.
