mdi - Display a WPF window inside another -

Before pointing to me or telling me that MDI is very shorter, 1995, let me explain my application.

I am creating a messagebanner window which works like a message banner today, we look at many sites today (including SO)

I want the client code to be my To make the message banner use four different methods, call:

<> MessageBanner.Show (content) ex; MessageBanner.Show (content, owner window); MessageBanner.ShowModal (content); MessageBanner.ShowModal (content, owner window);

I believe that you have received the application.

The thing is that when the owner window is displayed, then I want to display my messenger window inside the owner. Wando

Any ideas on how to do this?

I'm not sure why you want to add it to me as a window Just like you want to make it as a fluff rather than a window.
