title: Caliburn.micro : Bind two views of ViewModel with tab Control
body: <p>I  am trying to bind two views of viewmodel to two tabs of tab control by editing sample source code Caliburn.Micro.SimpleMDI included with Caliburn.Micro source. This project contains ShellViewModel and TabViewModel with TabView. I added one View named TabViewDetails. I edited ShellViewModel as follows.</p>
  
  <pre><code>public class ShellViewModel : Conductor&lt;IScreen&gt;.Collection.OneActive 
  {
      int count = 1;
  
      public void OpenTab()
      {
          TabViewModel  vm = null;
          if (Items.Count != 0)
          {
              vm = new TabViewModel() { DisplayName = "Detail Tab " + count++ };   
              var secondView = new TabViewDetails();
  
              ViewModelBinder.Bind(vm, secondView , null);
  
  
          }
          else
          {
              vm = new TabViewModel() { DisplayName = "Tab " + count++ }; 
          }
  
          ActivateItem(vm);
      }
  
  }
  </code></pre>
