I like to save the state of the report control when the user leaves it

or alternative

Start with som grouping based on one of the columns

Does any of the examples give some help.

look at the report grid same, it has the functions to save/restore the state of a reportbar.

(...\Codejock Software\MFC\Xtreme Toolkit Pro\Samples\ReportControl\ReportSample)

void CReportSampleView::LoadReportState()

{

#ifdef XML_STATE

CXTPPropExchangeXMLNode px(TRUE, 0, _T("ReportControl"));

if (!px.LoadFromFile(_T("c:\\ReportControl.xml")))

return;

m_wndReport.DoPropExchange(&px);

#else

UINT nBytes = 0;

LPBYTE pData = 0;

if (!AfxGetApp()->GetProfileBinary(_T("ReportControl"), _T("State"), &pData, &nBytes))

return;

CMemFile memFile(pData, nBytes);

CArchive ar (&memFile,CArchive::load);

try

{

m_wndReport.SerializeState(ar);

}

catch (COleException* pEx)

{

pEx->Delete ();

}

catch (CArchiveException* pEx)

{

pEx->Delete ();

}

ar.Close();

memFile.Close();

delete[] pData;

}

void CReportSampleView::SaveReportState()

{

#ifdef XML_STATE

CXTPPropExchangeXMLNode px(FALSE, 0, _T("ReportControl"));

m_wndReport.DoPropExchange(&px);

px.SaveToFile(_T("c:\\ReportControl.xml"));

CMemFile memFile;

CArchive ar (&memFile,CArchive::store);

m_wndReport.SerializeState(ar);

ar.Flush();

DWORD nBytes = (DWORD)memFile.GetPosition();

LPBYTE pData = memFile.Detach();

AfxGetApp()->WriteProfileBinary(_T("ReportControl"), _T("State"), pData, nBytes);

ar.Close();

memFile.Close();

free(pData);

HTH
