title: WPF ListView VerticalScrollBar is not shown
body: <p>I'm displaying a collection of items on a ListView. The collection is long enough to show the VerticalScrollBar of the ListView but it doesn't work.</p>
  
  <p>My XAML:</p>
  
  <pre><code>&lt;UserControl&gt;
      &lt;Grid&gt;
          &lt;ListView ItemsSource="{Binding MyCollection}"&gt;
              &lt;ListView.View&gt;
                  &lt;GridView&gt;
                      &lt;GridView.Columns&gt;
                          &lt;GridViewColumn DisplayMemberBinding="{Binding MyProperty}" Header="MyProperty" /&gt;
                          ...
                      &lt;/GridView.Columns&gt;
                  &lt;/GridView&gt;
              &lt;/ListView.View&gt;
          &lt;/ListView&gt;
      &lt;/Grid&gt;
  &lt;/UserControl&gt;
  </code></pre>
  
  <p>My UserControl is used like this:</p>
  
  <pre><code>&lt;Window&gt;
      &lt;Grid&gt;
          &lt;Grid.RowDefinitions&gt;
              &lt;RowDefinition Height="Auto" /&gt;
              &lt;RowDefinition Height="*" /&gt;
          &lt;/Grid.RowDefinitions&gt;
          &lt;Menu Grid.Row="0" IsMainMenu="True"&gt;
              &lt;MenuItem Header="_File" /&gt;
              ...
          &lt;/Menu&gt;
          &lt;TabControl Grid.Row="1" &gt;
              &lt;TabItem Header="myUserControl"&gt;
                  &lt;views:MyUserControl /&gt;
              &lt;/TabItem&gt;
              ...
          &lt;/TabControl&gt;
          ...
      &lt;/Grid&gt;
  &lt;/Window&gt;
  </code></pre>
