Problem deleting image property -- vb.net controls

I created an user control which contains an image property. Utilizing the
property page, I can select an image file, and the control will display it.
But, I'm unable to clear the value from the property page. That is, when I
select the entry in the property page, and hit the delete key, the property
page won't set the value to "none".

I have the property coded as:

Public Property MyImage() as Image
Get
Return _MyImage
End Get
Set (ByVal Value As Image)
_MyImage = Value
End Set
End Property

I'm assuming I'm missing something. Maybe an attribute? Anyone have any
ideas?

TIA,

Richard Rosenheim

I stumbled across the answer. I needed to add the DefaultValueAttribute to
the property. Specifically, the line:

<DefaultValue(GetType(Image), "None")>
