This is the scenario, I create an item that contains child items, I want to know when any of the child items' value has changed without having to write code in the child items OnValueChanged() to call the parent.

Yes, only with OnValueChanged :(

at least CXTPPropertyGridItemSize works this way:

class CXTPPropertyGridItemSize::CXTPPropertyGridItemSizeWidth : public CXTPPropertyGridItemNumber
{
public:
CXTPPropertyGridItemSizeWidth(LPCTSTR strCaption)
: CXTPPropertyGridItemNumber(strCaption)
{
}

virtual void OnValueChanged(CString strValue)
{
((CXTPPropertyGridItemSize*)m_pParent)->SetWidth(strValue);
}
virtual BOOL GetReadOnly() const
{
return m_pParent->GetReadOnly();
}
};

Thanks, that is what I thought, it would be cool to have a callback named something like OnChildValueChanged() though.
