title: c# webdriver - how can I verify 'disabled' attribute exists for a button
body: <p>I'm trying to verify that a button loacted within my test page has a 'disabled' attribute applied to it.  Here is the code:  </p>
  
  <pre><code>&lt;button type="button" class="btn-1" data-type="plus" data-field="quantity" disabled="disabled"&gt;
  </code></pre>
  
  <p>How would I go about getting a handle on the 'disabled' attribute?</p>
  
  <p>Many thanks for your help</p>
