title: XAML: How to set button in a template equal to a button in the class the template is for?
body: <p>I wanted to use buttons in code since they affect each other.</p>
  
  <p>I can use</p>
  
  <pre><code>public class ObservableButtons : ObservableCollection&lt;Button&gt; { }
  </code></pre>
  
  <p>but for just one button this seems a bit overkill.
  Is there an easier solution for this?</p>
  
  <p>Using a Trigger seems to be the smarter option atm, I'm just curious.</p>
