public void SetPropertyReadOnly(PropertyItem pProperty, bool pValue)
 {
            PropertyDescriptor descriptor = pProperty.PropertyDescriptor;
            ReadOnlyAttribute attribute = (ReadOnlyAttribute)
                                                  descriptor.Attributes[typeof(ReadOnlyAttribute)];
            FieldInfo fieldToChange = attribute.GetType().GetField("isReadOnly",
                                             System.Reflection.BindingFlags.NonPublic |
                                             System.Reflection.BindingFlags.Instance);
