title: Howto bind TextBox control to a StringBuilder instance?
body: <p>I would like several textboxes to react to changes of an underlying string. So if I were to change the content of the string, all those textboxes would change their content too.</p>
  
  <p>Now, I can't use the String type for that as it is immutable. So I went with StringBuilder. But the Text property of a TextBox object only takes String.</p>
  
  <p>Is there an easy way to "bind" the StringBuilder object to the Text property of a TextBox?</p>
  
  <p>Many thanks!</p>
  
  <p>PS: The TextBox is currently WPF. But I might switch to Windows Forms because of Mono.</p>
