title: databinding formatted text to a richtextbox in silverlight 4
body: <p>I need to databind formatted text to a RichTextBox. For formatting it seems that I will have to create a series of Runs with their specific formats and then add them to a paragraph and add it to the blocks property on the RichTextBox. I tried to bind a paragraph property to Blocks but it doesn't seem to allow that. Paragraph doesn't have an itemsource to bind it to a list of Runs. How can I possibly databind the list of Runs to a RichTextBox Widget ?</p>
  
  <p>Thanks</p>
