+The attached file does not have a DataGrid anywhere in the code.  I
+think you mean this:
+
+using System.Windows.Forms;
+
+class TestForm : Form
+{
+	static void Main ()
+	{
+		Application.Run (new TestForm ());
+	}
+
+	public TestForm ()
+	{
+		PropertyGrid p = new PropertyGrid ();
+		p.SelectedObject = new DataGrid ();
+	}
+}
+
+which results in the following NRE:
+
+Unhandled Exception: System.NullReferenceException: Object reference
+not set to an instance of an object
