title: WPF, Prism v2, Region in a modal dialog, add region in code behind
body: <p>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 I had this wizard showing up in a tab region and the nested region worked fine. Now I want to make it into a modal dialog box, but after I open it the inner region never gets registared with the region manager; So I can't add my wizard steps.</p>
  
  <p>I was under the impression that the region manager was global, and just adding cal:RegionManager.RegionName="WizardSteps" would do it, but apparently not. </p>
  
  <p>If i pass the region manager to the view I might be able to use it...Does anyone know how to add a region to a ContentControl in code behind?</p>
