What's the correct way to add a PageContent/ FixedPage to a FixedDocument in WPF?

Question

In WPF, in order to add a FixedPage to a FixedDocument in code one needs to:

var page = new FixedPage();
var pageContent = new PageContent();

((IAddChild)pageContent).AddChild(page);

This appears to be the only way, however:

The MSDN documentation explicitly says one shouldn't do this ('This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.'- PageContent.IAddChild.AddChild Method).
It's ugly to have to cast to an explicit interface implementation in order to add the content to PageContent.
It's not simple to perform the basic operation of PageContent.

The documentation doesn't actually explain how to do this and I couldn't find any other information on how to do it. Is there another way? A 'correct' way?

According to MSDN documentation, you simply add a FixedPage object to the PageContent.Child property and then add that to the FixedDocument by calling the FixedDocument.Pages.Add method.

For instance:

public FixedDocument RenderDocument() 
{
    FixedDocument fd = new FixedDocument();
    PageContent pc = new PageContent();
    FixedPage fp = new FixedPage();
    TextBlock tb = new TextBlock();

    //add some text to a TextBox object
    tb.Text = "This is some test text";
    //add the text box to the FixedPage
    fp.Children.Add(tb);
    //add the FixedPage to the PageContent 
    pc.Child = fp;
    //add the PageContent to the FixedDocument
    fd.Pages.Add(pc);

    return fd;
}

The MSDN documentation says the `PageContent.Child` property "Gets or **sets** the FixedPage associated with this PageContent." Here's the link: https://msdn.microsoft.com/en-us/library/system.windows.documents.pagecontent.child(v=vs.110).aspx – dtesenair Apr 17 '15 at 16:07

The `PageContent.Child` property supports both `get` and `set` at .NET 4 but only `get` at .NET 3.5 – Brian THOMAS Jul 27 '15 at 13:57
Try this:- ((System.Windows.Markup.IAddChild)pageContent).AddChild(fixedPage); – The Lonely Coder Oct 19 '15 at 14:33
what about PageContent.Source ? "The element has a single required attribute, Source, which refers to a FixedPage part" – juFo Nov 14 '18 at 14:25
