Selection Change NOTIFY

How do I pick up the action of the highlited row changing in a  CXTPReportControl?

Basically, the equivelant of OnSelChange() for a CListBox?

Thanks,

I've got the following code in my program.  OnReportItemClick works fine, and the pRow member is always the row at the index of the row clicked, but in the other handler, the pRow member is always the row from index zero, and thus, GetIndex() returns zero, instead of the correct index. 

What am I doing wrong?

ON_NOTIFY(NM_CLICK, IDC_RPT, OnReportItemClick)
ON_NOTIFY(XTP_NM_REPORT_SELCHANGED, IDC_RPT, OnSelectionChanged)

void CUnicorMedDlg::OnReportItemClick(NMHDR * pNotifyStruct, LRESULT * /*result*/)
{
 XTP_NM_REPORTRECORDITEM* pItemNotify = (XTP_NM_REPORTRECORDITEM*) pNotifyStruct;

 if (pItemNotify->pRow)
  int idx = pItemNotify->pRow->GetIndex();
}

void CUnicorMedDlg::OnSelectionChanged(NMHDR * pNotifyStruct, LRESULT * /*result*/)
{
 XTP_NM_REPORTRECORDITEM* pItemNotify = (XTP_NM_REPORTRECORDITEM*) pNotifyStruct;

 if (pItemNotify->pRow)
  int idx = pItemNotify->pRow->GetIndex();
}
