Question

I want to use a Wpf RichTextBox to edit data and resave it to SQL field.
I need of course the text to be saved as rich text, not just simple text of course.

1. What data-type should be best for storing in SQL server (2005 – forget about file stream)?
2. How do I save/retrieve it?

Answer 1

You can save the document to a XAML string using XamlWriter :

        StringWriter wr = new StringWriter();
        XamlWriter.Save(richTextBox.Document, wr);
        string xaml = wr.ToString();

You can then save the XAML string to a the database like any other text.

To reload it from a XAML string, use XamlReader :

        FlowDocument doc = XamlReader.Parse(xaml) as  FlowDocument;
