title: Styles overwriting in WPF
body: <p>I'm using <a href="http://mahapps.com/MahApps.Metro/" rel="noreferrer">MahApps.Metro</a> to achieve Metro UI in my app.</p>
  
  <p>I have a listview and MahApps.Metro is changing style for it. MahApps styles for listview are <a href="https://github.com/MahApps/MahApps.Metro/blob/master/MahApps.Metro/Styles/Controls.ListView.xaml" rel="noreferrer">here</a>.</p>
  
  <p>Loading of styles:</p>
  
  <pre><code>&lt;Window.Resources&gt;
      &lt;ResourceDictionary&gt;
          &lt;ResourceDictionary.MergedDictionaries&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colours.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedSingleRowTabControl.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" /&gt;
              &lt;ResourceDictionary Source="pack://application:,,,/FineRSS;component/Resources/Icons.xaml" /&gt;
          &lt;/ResourceDictionary.MergedDictionaries&gt;
      &lt;/ResourceDictionary&gt;
  &lt;/Window.Resources&gt;
  </code></pre>
  
  <p>I need to keep track of selected listviewitems so I'm using the next approach:</p>
  
  <pre><code>&lt;ListView.ItemContainerStyle&gt;
                  &lt;Style TargetType="{x:Type ListViewItem}"&gt;
                      &lt;Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}"/&gt;
                  &lt;/Style&gt;
  &lt;/ListView.ItemContainerStyle&gt;
  </code></pre>
  
  <p>But MahApps.Metro's style is overwritten to ListView's default.</p>
  
  <p>What can I do to keep either styles and IsSelected binding? </p>
