title: How to enable horizontal scrolling in ListView in WinRT
body: <p>I am creating a Windows 8.1 application and I have a list view where every row can extend beyond the screen limits. I want to allow the use to scroll left and right when the row is wide, but I can't seem to get the horizontal scroll viewer to appear event when setting its properties explicitly. </p>
  
  <pre><code>    &lt;ListView
          ItemsSource="{Binding AllColors}"
          ScrollViewer.HorizontalScrollBarVisibility="Visible"
          ScrollViewer.HorizontalScrollMode="Enabled"
          &gt; 
          &lt;ListView.ItemContainerStyle&gt;
              &lt;Style TargetType="ListViewItem"&gt;
                  &lt;Setter Property="Width" Value="3600"/&gt;
                  &lt;Setter Property="HorizontalAlignment" Value="Stretch"/&gt;
                  &lt;Setter Property="HorizontalContentAlignment" Value="Stretch"/&gt;
              &lt;/Style&gt;
          &lt;/ListView.ItemContainerStyle&gt;
          &lt;ListView.ItemTemplate&gt;
              &lt;DataTemplate&gt;
                  &lt;Rectangle Height="100"&gt;
                      &lt;Rectangle.Fill&gt;
                          &lt;LinearGradientBrush&gt;
                              &lt;GradientStop Offset="0" Color="Black"/&gt;
                              &lt;GradientStop Offset="0.5" Color="{Binding}"/&gt;
                              &lt;GradientStop Offset="1" Color="White"/&gt;
                          &lt;/LinearGradientBrush&gt;
                      &lt;/Rectangle.Fill&gt;
                  &lt;/Rectangle&gt;
              &lt;/DataTemplate&gt;
          &lt;/ListView.ItemTemplate&gt;
      &lt;/ListView&gt;
  </code></pre>
  
  <p>The horizontal scroll bar appears, but it does not allow scrolling (as if there is no need to...) while the items inside it are much wider then the screen.</p>
  
  <p>Is there a way to do that?</p>
