Expand a class instance within a class instance in PropertryGrid

Question

In C#, I have a class set up like so:

class Page
{
  public class Element
  {
   private string test;
   public string Test
   { get { return test; } set { test = value; } }
  }

 private Element element;
 public Element PrimaryElement
 { get { return element; } set { element = value; } }
}

If I have a PropertyGrid where the select object is an instance of Page, how can I modify Test in its member PrimaryElement from the PropertyGrid? It shows up in grey and is not expandable nor editable.

Add this to your Element type or to your PrimaryElement property:

[TypeConverter(typeof(ExpandableObjectConverter))]
