Wpf Prism MVVM change between modules

Question

I'm working on a WPF project using Prism and MVVM, I'm new using this tools. I've been creating modules and testing it and everything works fine. To test it in the Bootstrapper I add each module using AddModule method of the ModuleCatalog, but now I need to put all my modules together and go from one module to another.

Program starts and load Module_1, when the user finish all in this module press a complete button and the program shows Module_2 and so on...

What I need to do to change from one module to another after an user action?

Thank you in advance.

Module can be loaded on demand. After pressing complete button in the first module load Module_2. How to: Load Modules on Demand. In the module's Initialize() method you can register views you need with regions, e.g.

public void Initialize()
{
    regionManager.RegisterViewWithRegion("MainRegion", () => container.Resolve<Module2View>());
}

After load module completed navigate to this view:

moduleManager.LoadModuleCompleted += (s, e) =>
    {
        if (e.ModuleInfo.ModuleName == "Module_2")
        {
            regionManager.RequestNavigate("MainRegion", new Uri("Module2View", UriKind.Relative));
        }
    };

It's just a quick sample. You can find more information on MSDN. Hope it helps.
