Question

Convert XAML to FlowDocument to display in RichTextBox in WPF

Answer 1

+1 A:

I assume it crashes on Add() because you are adding a FrameworkContentElement which already has a logical parent. You must first remove a Block from its parent and only then add it to a different collection. Try this:

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

unfortunately this is also crashing as Section sec is remaining null =/ I've added a sample of what i'm trying to convert

It appears your XAML string actually represents a `FlowDocument`. Then things are much simpler. Just do a `return XamlReader.Load(xmlReader) as FlowDocument;` and you're done.
