How to dynamically embed a XAML/Codebehind pair as a child of a StackPanel?

Question

I have a StackPanel called "MainContent".

I can dynamically fill it with UIElements like this:

TextBlock textBlock = new TextBlock();
textBlock.Text = String.Format("This is text");
textBlock.Background = new SolidColorBrush(Colors.Beige);
MainContent.Children.Add(textBlock);

Button button = new Button();
button.Content = "This is a button";
MainContent.Children.Add(button);

But I want to go beyond that and fill it with a XAML/Codebehind pair (e.g. Page or Window):

Type type = this.GetType();
Assembly assembly = type.Assembly;
Window window = (Window)assembly.CreateInstance(String.Format("{0}.{1}", type.Namespace, "Test1"));
MainContent.Children.Add(window);

But the above code complains that I can't add a "Window to a Visual". I can do window.ShowDialog() of course but then it is external to my main window. I want the Test1 window to be embedded in my application.

How can I do this?

Added: The main question is: how can I get Window (or Page) to act as a UIElement so I can embed them dynamically in StackPanels, etc. Currently looking at XamlLoader, anyone experienced with that?

Answer 1

I don't know if it's possible. But instead of filling the panel with a Window, why not fill it with the root element of the window instead. You'll get all the content and value of the window without the unneeded chrome.

Update: you can grab the root element of a window via the Dependency Property Content

    Window w;
    object rootElement = w.Content;

Answer 2

Have you tried this?

MainContent.Children.Add(window.Content);

The easiest way is to have your XAML/code behind inherit from UserControl - and then everything will just work
