title: Getting value from style setter property in xaml
body: <p>How can I get the value of style setter property in xaml?</p>
  
  <p>For example, I have next style:</p>
  
  <pre><code>&lt;Style TargetType="TextBox"&gt;
      &lt;Setter Property="Background" Value="YellowGreen" /&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>How can I get the value of Background property from TextBox default style?</p>
  
  <pre><code>&lt;Style TargetType="Button"&gt;
      &lt;Setter Property="Background" Value="{Binding ???}" /&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>I need this because <strong>I haven't access to <code>TextBox</code> style</strong>..</p>
