title: MVVM Passing data between two views / view models
body: <p>I have two Pages:</p>
  
  <ol>
  <li>Page 1</li>
  <li>Page 2</li>
  </ol>
  
  <p>and two ViewModels with the same properties:</p>
  
  <ol>
  <li><strong>ViewModel1</strong> <br>
  Properties:
  <ul>
  <li>FirstName1</li>
  <li>LastName1</li>
  </ul></li>
  <li><strong>ViewModel2</strong><br>
  Properties:
  <ul>
  <li>FirstName2</li>
  <li>LastName2</li>
  </ul></li>
  </ol>
  
  <p>Now I want to pass data(properties) between ViewModel1 to ViewModel2, and retrive this data on the Page 2.
  How do I achieve this? </p>
