How to display short read only FlowDocument in a label-like control

I am looking for a way to present short FlowDocument strings in a label-like control.

In WPF the user can input text into a RichTextBox. The result is a FlowDocument string. I'm looking for a way to present that text in a Label, in which:

1. The user should not be able to edit or select (with the mouse) the text.
2. There should be no scroll bars - like in a normal label the control should expand to accommodate all the text.
3. If the user scrolls while the mouse is on the label, the control that should scroll is the parent of the control
4. The control should be as lightweight as possible.

I have the following implementation that inherits FlowDocumentScrollViewer but I am sure there must be a better implementation (possibly inheriting other control than FlowDocumentScrollViewer).

public class FlowDocumentViewer : FlowDocumentScrollViewer
{
    public FlowDocumentViewer()
    {
        this.SetValue(ScrollViewer.CanContentScrollProperty, false);
        this.SetValue(ScrollViewer.VerticalScrollBarVisibilityProperty, ScrollBarVisibility.Hidden);
        this.Padding = new Thickness(-17);
        this.Document = new FlowDocument();
    }

    protected override void OnMouseWheel(MouseWheelEventArgs e)
    {
        e.Handled = false;
    }

    public string Text
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }

    public static readonly DependencyProperty TextProperty =
        DependencyProperty.Register("Text", typeof(string), typeof(FlowDo开发者_高级运维cumentViewer), new UIPropertyMetadata(string.Empty, TextChangedHandler));

    private static void TextChangedHandler(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (e.NewValue.Equals(string.Empty))
            return;
        FlowDocumentViewer fdv = (FlowDocumentViewer)d;
        fdv.Document.Blocks.Clear();

        using (MemoryStream stream = new MemoryStream(UTF8Encoding.UTF8.GetBytes(e.NewValue.ToString())))
        {
            Section content = XamlReader.Load(stream) as Section;
            fdv.Document.Blocks.Add(content);
        }
    }
}

Have you tried setting IsReadOnly?

    <RichTextBox  IsReadOnly="True"/>

I think this XAML meets all of your requirements; it should be trivial to make a user control out of it. Just implement a FlowDocument dependency property that sets the RichTextBox's Document property.

Most of what you see below is just greeked text so that you can see how it functions when you paste it into Kaxaml or whatever; the core of it is a Grid containing a RichTextBox with a transparent Border over it so that it doesn't capture mouse events or keystrokes.
