title: How can you store state between screens in SketchFlow?
body: <p>I'm building a prototype using Expression Blend 3 and SketchFlow (a Silverlight SketchFlow application to be specific) and it consists of multiple screens that I want to share state between.</p>
  
  <p>Take this example:</p>
  
  <ol>
  <li><p>Screen 1 - 'Login' screen: I want the user to type in a fake user name and password.</p></li>
  <li><p>Screen 2 - 'Home' screen: I want to display that user name so the user sees that their input is reflected.</p></li>
  </ol>
  
  <p>This is just a trivial example and not something that most prototypes need to demonstrate, but the same functionality could be used in an application where <strong><em>the selection on one screen needs to be persisted for the next screen</em></strong>.</p>
  
  <p>How can I do this in SketchFlow?  I know that I can write Silverlight code to store some data in isolated storage, but I'm trying to go with the 'zero code' approach since this will be a throw-away prototype and would prefer to use some built-in mechanism in SketchFlow if available.</p>
  
  <p><strong>Does Sketchflow offer a way to state data between screens?</strong></p>
