title: How can I suppress a ListView from displaying when content when empty
body: <p>I have an object that contains an IEnumerable called ValidPhones as a property. When I bind it to a WPF ListView like such:</p>
  
  <pre><code>&lt;ListView DataContext="{Binding ValidPhones}"&gt;
    &lt;TextBlock&gt;
      &lt;TextBlock.Text&gt;
        &lt;MultiBinding StringFormat='{}{0}: {1}'&gt;
          &lt;Binding Path='Type' /&gt;
          &lt;Binding Path='PhoneNumber' /&gt;
        &lt;/MultiBinding&gt;
      &lt;/TextBlock.Text&gt;
    &lt;/TextBlock&gt;
  &lt;/ListView&gt;
  </code></pre>
  
  <p>It still ends up displaying the ": " in the UI even when the Enumerable is empty. Is there a simple way to suppress that from happening?</p>
