Binding errors all over the place for very simple PropertyGrid....

I noticed that PropertyGrids seemed particularly slow in my project that I was making and I figured I was doing something wrong with my styling somewhere causing a bunch of problems. That's when I turned on 

PresentationTraceSources.DataBindingSource.Listeners.Add(new ConsoleTraceListener());
PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All;

 to watch for any binding errors. And I got hundreds. So I at first assumed it was something I was doing, but when I isolated it to a new project, I got the same errors. 

Most of which looked like this (x1000):

System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=ModifiedPropertyDisplayMode; DataItem=null; target element is 'TreeListViewCell' (Name=''); target property is 'NoTarget' (type 'Object')
System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=ModifiedPropertyDisplayMode; DataItem=null; target element is 'TreeListViewCell' (Name=''); target property is 'NoTarget' (type 'Object')

Looking into it, I guess this is caused when a binding fails and there is no fallback value. But I happens with EVERY binding for some reason. Normally, a few of these would be ignorable, but when there are hundreds, things start to run very slowly.  

The XAML:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:propgrid="http://schemas.actiprosoftware.com/winfx/xaml/propgrid"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <propgrid:PropertyGrid x:Name="propertyGrid" >
        </propgrid:PropertyGrid>
    </Grid>
</Window> 

The code:

using System.ComponentModel;
using System.Diagnostics;
using System.Windows;
using System.Windows.Media;
using ActiproSoftware.Windows.Controls.Editors.Interop.PropertyGrid.PropertyEditors;
using ActiproSoftware.Windows.Controls.PropertyGrid.Editors;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            PresentationTraceSources.DataBindingSource.Listeners.Add(new ConsoleTraceListener());
            PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All;
            InitializeComponent();

            this.Loaded += (o, e) =>
                {
                    propertyGrid.SelectedObject = new Foo();
                };
        }
    }

    public class Foo
    {
        public Foo()
        {
            Color = Colors.White;
        }
 
        [DisplayName("Color")]
        [Category("Colors")]
        [Description("Colors")]
        [Editor(typeof(ColorPropertyEditor), typeof(PropertyEditor))]
        public Color Color { get; set; }

        [DisplayName("Number")]
        [Category("Numbers")]
        [Description("Numbers")]
        [Editor(typeof(DoublePropertyEditor), typeof(PropertyEditor))]
        public float Number { get; set; }

        [DisplayName("Number2")]
        [Category("Numbers")]
        [Description("Numbers")]
        [Editor(typeof(DoublePropertyEditor), typeof(PropertyEditor))]
        public double Number2 { get; set; }
    }
}

Not sure how to fix these problems, but it seems to cause quite a large bog on the system.
