Hello.

After I converted my .net code to the new VC2005 syntax I started to get
C4490 on my ExpandableObjectConverter subclass overrides. The GetProperties
method is no longer called by the PropertyGrid when I use my subclass as a
type converter.

Can anyone tell me what has changed? What's the correct way to override
GetProperties method? Here's the code for my class:

// ExpandableProperty.h
#pragma once

using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Diagnostics;

public ref class TExpandableProperty : public ExpandableObjectConverter
{
public:
 TExpandableProperty();

 virtual PropertyDescriptorCollection^
GetProperties(ITypeDescriptorContext^, Object^, Attribute^ attributes)
override { return GetProperties(); }
 virtual PropertyDescriptorCollection^ GetProperties(Object^) override {
return GetProperties(); }
 virtual PropertyDescriptorCollection^
GetProperties(ITypeDescriptorContext^, Object^) override { return
GetProperties(); }
 virtual PropertyDescriptorCollection^ GetProperties() override { return
propertyCollection; }

 virtual bool GetPropertiesSupported(ITypeDescriptorContext^) override {
return true; }
 virtual bool GetPropertiesSupported() override { return true; }

 bool AddProperty(PropertyDescriptor ^propertyDescriptor);

private:
 PropertyDescriptorCollection ^propertyCollection;
};

// ExpandableProperty.cpp

#include "StdAfx.h"
#include ".\expandableproperty.h"
#using <mscorlib.dll>

//-----------------------------------------------------------

TExpandableProperty::TExpandableProperty()
{
propertyCollection = gcnew PropertyDescriptorCollection(nullptr);
}

//-----------------------------------------------------------

bool TExpandableProperty::AddProperty(PropertyDescriptor^
propertyDescriptor)
{
propertyCollection->Add(propertyDescriptor);
return true;
}

Thanks in advance for any help.

Regards,
Adriano.
