MSFlexGrid is a useful control to present data in a Grid, but what happens when this content has to be printed? Here I present a class, PrintGrid, that paginates and prints the grid content. It uses a second Grid control and must be additionally inserted in your CFormView dialog resource or in your dialog.

The instructions are as follows:

• Add a second MSFlexGrid control to your form or dialog.
• Change the member in your view or dialog class from CMSFlexGrid to CPrintGrid* m_pxPrintGrid.
• Change the DDX command: DDX_Control(pDX, IDC_MSFLEXGRID2, *m_pxPrintGrid).
• Instantiate the control in your constructor: m_pxPrintGrid = new CPrintGrid().
• Override the operation OnPreparePrinting and OnPrint as follows:

BOOL MyFormView::OnPreparePrinting(CPrintInfo* pInfo)

{

  // Calculate pages for all grid data

  CPrintDialog xPrintDlg(FALSE);

  CDC xDC;

  xPrintDlg.GetDefaults();

  xDC.Attach(xPrintDlg.GetPrinterDC());

  m_pxPrintGrid->Paginate(&xDC, m_pxGrid);

  xDC.Detach();

  // Update the number of pages according to DC size

  pInfo->m_nNumPreviewPages = m_pxPrintGrid->GetNumPages();

  pInfo->SetMinPage(1);

  pInfo->SetMaxPage(m_pxPrintGrid->GetNumPages());
  // Display printer setup dialog and initialize CPrintInfo

  if (!DoPreparePrinting(pInfo))

  {

    return FALSE;

  }

  // call parent

  return CFormView::OnPreparePrinting(pInfo);

}
void MyFormView::OnPrint(CDC* pDC, CPrintInfo* pInfo)

{

  CString sTitle;

  sTitle = “My App title”;

  m_pxPrintGrid->PrintPage(pDC, pInfo->m_nCurPage, m_pxGrid,

                           sTitle);

  // Call parent

  CFormView::OnPrint(pDC, pInfo);

}

Enjoy it! I hope it will be useful.
