title: Button tooltip not getting localized
body: <p>I have an extended button class as follows;</p>
  
  <pre><code>class ExtendedButton : Button
  {
      private ToolTip _tooltip = new ToolTip();
  
      public ExtendedButton()
      {
          _tooltip.SetToolTip(this, StringResources.MyLocalizedTooltipString);
      }
  }
  </code></pre>
  
  <p>In above code, 'StringResources.MyLocalizedTooltipString' contains strings for various languages. But when I change thread culture, tooltip text does not get changed. How to achieve that? 
  Any help would be appreciated.</p>
