It seems that we have missunderstood your scenario, our previous response was based on our understanding of the approach used to create a dialog or modal window with the
WindowDialogActivationBehavior provided in the StockStrader RI.
On the other hand regarding the use of a InteractionRequest in WPF, you might find that the samples applications provided by Prism out of the box which implement this approach are targeted only to Silverlight (e.g.
StateBased Navigation Quickstart and
ViewSwitching Navigation Quickstart). The implementation mechanism for WPF should be the same, except that in WPF there is no implementation of "ChildWindow" and you might have
to design a custom dialog window.
You might find that this is also addressed in the following Codeplex
discussion, where Karl Shifflet posted that he provided a WPF version of the
InteractionRequest in his
In The Box MVVM Training (specifically in DialogInteractionRequestView.xaml of the MVVM Scenarios application).
If you find that this is not useful regarding you scenario, it would be helpful to us if you could provide us with a little more information so we could help you futher with this.
I hope you find this handy,
