Always show selection

I found a way to do this.

In my CustomRecord class derived from CXTPReportRecord, i redefine GetItemMetrics() :
void CustomRecord::GetItemMetrics( XTP_REPORTRECORDITEM_DRAWARGS* pDrawArgs, XTP_REPORTRECORDITEM_METRICS* pItemMetrics )
{
     if(pDrawArgs->pRow->IsSelected())// to highlight selected row even if the control hasnt the focus
     {
          CXTPReportPaintManager *pPaintManager = pDrawArgs->pControl->GetPaintManager();
          pItemMetrics->clrForeground = pPaintManager->m_clrHighlightText;
          pItemMetrics->clrBackground = pPaintManager->m_clrHighlight;
     }
     else
     if ((pDrawArgs->pRow->GetIndex() % 2) && !pDrawArgs->pItem->IsPreviewItem())//one row on two will be a little bit grey
     {
          pItemMetrics->clrBackground = RGB(240, 240, 240);
     }
}

and i set the "m_bHideSelection" of the paintManager of the ReportControl to TRUE in the init() of my view
m_report_elements.GetPaintManager()->m_bHideSelection = TRUE;
