WPF, Prism v2, Region in a modal dialog, add region in code behind

Question

I have a composite WPF application. In one of my modules I want to make a wizard and have the steps show up in a region so I can switch between the steps easier. Originally

Answer 1

It is actually quite simple.

In your popup xaml add a regionname as you do in the shell. Then in the popups constructor, add the following call:

public Popup(IRegionManager regionManager)
{
     InitializeComponent();
     RegionManager.SetRegionManager(this,regionManager);
}

This works for me in Prism v.1 - shouldn't be too much different in later versions.
