title: How to convert FlowDocument to rtf
body: <p>I have used a WPF RichTextBox to save a flowdocument from it as byte[] in database. Now i need to retrieve this data and display in a report RichTextBox as an rtf.
  when i try to convert the byte[] using TextRange or in XAMLReader i get a FlowDocument back but how do i convert it to rtf string as the report RichTextBox only takes rtf.</p>
  
  <p>Thanks</p>
