Accelerators processing before CMFCPropertyGridCtrl

I am having a problem with accelerators processing before CMFCPropertyGridCtrl. So if you are editing a text box and press 'delete', it executes the accelerator command instead of deleteing a character in the edit box. How can I resolve this issue?

Implement the PreTranslateMessage function and, depending on whether the property grid has focus or not, pass the message to accelerator or not.

Code:

  m_hAccel = ::LoadAccelerators(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDR_MYDIALOG));


BOOL CMyDialog::PreTranslateMessage(MSG* pMsg) {

  ...

  if(m_hAccel && ...not grid has focus...) {
    if(::TranslateAccelerator(m_hWnd, m_hAccel, pMsg))
      return(TRUE);
  }

 return CDialog::PreTranslateMessage(pMsg);
}
