title: WPF - Border template with content
body: <p>Let's assume I have the following control template:</p>
  
  <pre><code>&lt;ControlTemplate x:Key="Test"&gt;
      &lt;Grid&gt;
          &lt;Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1" Width="33" Height="33" CornerRadius="3"/&gt;
          &lt;ContentControl Content="{TemplateBinding Property=ContentControl.Content}" VerticalAlignment="Center" HorizontalAlignment="Center"/&gt;
      &lt;/Grid&gt;
  &lt;/ControlTemplate&gt;
  </code></pre>
  
  <p>How can I change content of the control in wpf? I've tried something like</p>
  
  <pre><code>&lt;Control Template="{StaticResource Test}" BorderBrush="Black" Content="aa"&gt;&lt;/Control&gt;
  </code></pre>
  
  <p>But when I do so I it says me that the property content is not recognized or it is not found.</p>
