title: Sitecore - Adding button to FormDialog
body: <p>Is it possible to add a custom button to a Sitecore FormDialog other than OkButton and CancelButton e.g. instead of this</p>
  
  <pre><code>&lt;FormDialog Icon="cool.png" Header="A really cool header" Text="Link or un-link items" OKButton="Link" CancelButton="Close"&gt;
  </code></pre>
  
  <p>but something more like this</p>
  
  <pre><code>&lt;FormDialog Icon="cool.png" Header="A really cool header" Text="Link or un-link items" OKButton="Link" UnLinkButton="UnLink" CancelButton="Close"&gt;
  </code></pre>
