Answer 2

+1 A:

Retrive a XAML text from RichTextBox:

private static string GetRTF(RichTextBox rt)
{
    TextRange range = new TextRange(rt.Document.ContentStart, rt.Document.ContentEnd);
    MemoryStream stream = new MemoryStream();
    range.Save(stream, DataFormats.Xaml);
    string xamlText = Encoding.UTF8.GetString(stream.ToArray());
    return xamlText;
}

Render a XAML text into a RichTextBox:

private static FlowDocument SetRTF(string xamlString)
{
    StringReader stringReader = new StringReader(xamlString);
    XmlReader xmlReader = XmlReader.Create(stringReader);
    Section sec = XamlReader.Load(xmlReader) as Section;
    FlowDocument doc = new FlowDocument();
    while (sec.Blocks.Count > 0)
        doc.Blocks.Add(sec.Blocks.FirstBlock);
    return doc;
}
