C# .Net 4.5 PropertyGrid: how to hide Properties

Question

The problem is simple(and I hope that this have a simple solution!): I want to hide ( Browsable(false) ) the property "Element" (in my PropertyGrid object) when it's zero.

    public class Question
    {
       ...

      public int Element
      {
        get; set;
      }
    }

What you could do is reuse the DynamicTypeDescriptor class described in my answer to this question here on SO: PropertyGrid Browsable not found for entity framework created property, how to find it?

like this for example:

public Form1()
{
    InitializeComponent();

    DynamicTypeDescriptor dt = new DynamicTypeDescriptor(typeof(Question));

    Question q = new Question(); // initialize question the way you want    
    if (q.Element == 0)
    {
        dt.RemoveProperty("Element");
    }
    propertyGrid1.SelectedObject = dt.FromComponent(q);
}
