Question

I’m starting a new project in WPF and am now looking into using Prism. For now I’m simply trying to set up the navigation of the application using Prism. Unfortunately, my lack of experience with the framework makes it a bit difficult to get started.

To be more precise about my first challenge I have an application with a “navigation/menu” region and a “main” region.

In “navigation/menu” region, I have several checkboxes, in this case we have four of them, which represents a sequential navigation. I.E. we’ve selected View 2 and View 4.

So, when the user click Start, in “main” region must appear each view selected in that order. Check the below image, View 2 is first. Then when the user press next, must show View 4.

I mean on a more structural level..

if I could only get through the first steps..

Answer 1

Prism support TabControl Region Adapter, navigation can be done using standard requestNavigation method.

1. You need add all your tab content using Region.Add method to the region in your module’s init phase.

   view:

   <TabControl prism:RegionManger.RegionName="tabRegion" />
   

   C# code:

   IRegionManager manager;
   manager.Regions["tabRegion"].Views.Add(Container.Resolve(typeof(YourViewType)));
   

2. In your viewModel, you should write you navigation command:

   public void NextView() {
       regionManager.RequestNavigation("tabRegion", new Uri("YourViewType", UriKind.Relative));
   }
   

   bind to your “next” button:

   <Button Command="{Binding NextViewCommand}" />
   

3. If you want to control whether user can navigate to next page, you can implement INavigationAware interface.

4. If you don’t want lost data between navigation, you can make your view model has ContainerMangedLifeCycle or implement IsNavigationTarget method to return true.

Sorry for untested code sample, but you should get the point.
