        e.Properties.Remove(e.Properties["Content"]);
}

VB.NET

Private Sub diagram_CustomGetSerializableItemProperties(ByVal sender As Object, ByVal e As DiagramCustomGetSerializableItemPropertiesEventArgs)
    If GetType(DiagramContentItem).IsAssignableFrom(e.ItemType) Then
        e.Properties.Remove(e.Properties("Content"))
    End If
End Sub
