title: Binding List<string> property to Listbox WPF
body: <p>Can someone help me? I have the folowing XAML code in my MainWindow.xaml file:</p>
  
  <pre><code>       &lt;ListBox ItemsSource="{Binding Files}" HorizontalAlignment="Left" 
                  Height="371"   Margin="281,53,0,0" VerticalAlignment="Top" 
                  Width="609"&gt;
               &lt;ListBox.ItemTemplate&gt;
                  &lt;DataTemplate&gt;
                      &lt;StackPanel Orientation="Horizontal"&gt;
                          &lt;TextBlock Text="{Binding}" /&gt;
                      &lt;/StackPanel&gt;
  
                  &lt;/DataTemplate&gt;
              &lt;/ListBox.ItemTemplate&gt;
          &lt;/ListBox&gt;
  </code></pre>
  
  <p>And in my ViewModel.cs I have property:</p>
  
  <pre><code>public List&lt;string&gt; Files { get; set; }
  </code></pre>
  
  <p>But, when I click the button and add some items to Files nothing happens.</p>
  
  <p>P.S. Sorry for my bad English :)</p>
