title: PropertyGrid - get chosen bitmap's file path
body: <p>I set a <code>PropertyGrid</code>'s <code>SelectedObject</code> to an object with a <code>Bitmap</code> property:</p>
  
  <pre><code>public class Obj
  {   
      private Bitmap myimage;
      [Category("Main Category")]
      [Description("Your favorite image")]
      public Bitmap MyImage
      {
          get { return myimage; }
          set
          {
              myimage = value;
          }
      }
  }
  </code></pre>
  
  <p>This automatically shows the property in the <code>PropertyGrid</code> with a little button that the user can click on to select the image. How can I get the file path of this image?</p>
  
  <p>(Also, is there any way I can override the dialog box that pops up and put my own one in? I know this is a separate question so I'll probably post it separately.)</p>
