Detecting Element Visibility in WatiN

I recently needed to check the visibility of an element in a WatiN test and I came across a very helpful post by Ashley Tate. I turned his method into the following extension method which makes my tests nice and easy.

   1:  public static class ElementExtensions

   2:  {

   3:      public static bool IsDisplayed(this Element element)

   4:      {

   5:          if (string.Equals(element.Style.Display, "none"))

   6:          {

   7:              return false;

   8:          }

   9:          return element.Parent == null || element.Parent.IsDisplayed();

  10:      }

  11:  }
