   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.
