title: How to change Label Text color of masterPageitem after selection
body: <p>I'm new to Xamarin framework and want to create an app using Master-Detail Page
  I did simple Master-Detail Navigation page demo from xamarin websit 
  <a href="https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/navigation/master-detail-page/" rel="nofollow noreferrer">master-detail-page xamarin webise</a></p>
  
  <p>only difference is I used ViewCell inside DataTemplate.In ViewCell I have Label
  instead of Image.
  after clicking on <code>MasterPageItems</code> navigation is working fine but now I want to <strong>change the label Text color</strong> also .</p>
  
  <pre><code>      &lt;ListView x:Name="listView" VerticalOptions="FillAndExpand" SeparatorVisibility="None" RowHeight="50" &gt;
      &lt;ListView.ItemTemplate&gt;
        &lt;DataTemplate&gt;
          &lt;ViewCell&gt;
            &lt;Label Text="{Binding Title}" TextColor="#1ca7ec" FontSize="18"&gt;&lt;/Label&gt;
          &lt;/ViewCell&gt;
        &lt;/DataTemplate&gt;
      &lt;/ListView.ItemTemplate&gt;
    &lt;/ListView&gt;
  
  void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
      {
          var item = e.SelectedItem as MasterPageItem; 
          if (item != null)
          {                
              Detail = new NavigationPage((Page)Activator.CreateInstance(typeof(ContactsPage)));
              masterPage.ListView.SelectedItem = null;
              IsPresented = false;
          }
      }
  </code></pre>
