Play-To Won't Work for Secondary Views

Question

I have a Xaml/C# Windows 8.1 app that creates a secondary window using CoreApplication.CreateNewView() and ApplicationViewSwitcher.TryShowAsStandaloneAsync()

In the OnNavigatedTo() override for the new page, I am calling

                PlayToManager.GetForCurrentView().SourceRequested += this.OnSourceRequested

But I am finding that when the secondary view is active, the OnSourceRequested never gets called.

If I call add the event handler for

                PlayToManager.GetForCurrentView().SourceRequested += this.OnSourceRequested

To my primary view, it does get called.

1. Is there anything that I must do to enable new windows for my app to support Play-To source requests?
2. Is this a limitation of the platform or is it a bug?

Thanks,

Michael

Answer 1

Have you tried calling that in a dispatcher?

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Matt,

I've tried attaching the SourceRequsted event handler in a Dispatcher but that didn't fix it - the SourceRequested event handler only gets called for the initial window, not a secondary window.
