title: XAML Binding to label
body: <p>In Xamarin.Forms I have a page for displaying database items.</p>
  
  <pre><code>public ListItemsPage()
  {
      DatabaseHelper tmpDBHelper = new DatabaseHelper();
      InitializeComponent();
  
      listView.ItemsSource = tmpDBHelper.GetItems();
  }
  </code></pre>
  
  <p>These items have 4 columns: Id as <code>Guid</code>, MandantId as <code>Guid</code>, UpdateAt as <code>DateTime</code> and Url as <code>String</code>.</p>
  
  <p>Now I'd like to bind them in my XAML like this.</p>
  
  <pre><code>&lt;ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
               xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
               x:Class="Portable.Pages.ListItemsPage"
               Title="DbItemExample"&gt;
    &lt;ListView x:Name="listView"&gt;
      &lt;ListView.ItemTemplate&gt;
        &lt;DataTemplate&gt;
          &lt;ViewCell&gt;
            &lt;ViewCell.View&gt;
              &lt;StackLayout Padding="20,0,20,0"
                           Orientation="Horizontal"
                           HorizontalOptions="FillAndExpand"&gt;
  
                &lt;Label Text="{Binding Id}"
                       HorizontalOptions="StartAndExpand" /&gt;
                &lt;Label Text="{Binding Url}"
                                     HorizontalOptions="StartAndExpand" /&gt;
                &lt;Label Text="{Binding MandantId}"
                                     HorizontalOptions="StartAndExpand" /&gt;
                &lt;Label Text="{Binding UpdateAt}"
                                     HorizontalOptions="StartAndExpand" /&gt;
              &lt;/StackLayout&gt;
            &lt;/ViewCell.View&gt;
          &lt;/ViewCell&gt;
        &lt;/DataTemplate&gt;
      &lt;/ListView.ItemTemplate&gt;
    &lt;/ListView&gt;
  &lt;/ContentPage&gt;
  </code></pre>
  
  <p>If this helps, here is my model of which the db table was generated.</p>
  
  <pre><code>class DbItem
  {
      [PrimaryKey]
      public Guid Id { get; set; }
      public Guid MandantId { get; set; }
      public string Url { get; set; }
      public DateTime UpdateAt { get; set; }
  }
  </code></pre>
  
  <p>It's only displaying the Url and UpdateAt. Why is that?</p>
