有人遇到过使用delphi自带的QReport报表只能打印第一页和最后一页的问题吗？

我使用delphi自带的报表控件，可是在打印时，本来有8页的报表，却只能打印出第一页
和最后一页。

请各位高手给我讲一下是什么问题，万分感激。可以会贴，也可发到我的油箱：

代码如下：///报表窗口，自己没有写代码，就是放了几个控件。
///不知道是否在换页时要写代码？请各位高手指点
unit repLogFrm;

interface

uses Windows, SysUtils, Messages, Classes, Graphics, Controls,
  StdCtrls, ExtCtrls, Forms, Quickrpt, QRCtrls;

type
  TrepLog = class(TQuickRep)
    ColumnHeaderBand1: TQRBand;
    DetailBand1: TQRBand;
    TitleBand1: TQRBand;
    QRLabel1: TQRLabel;
    QRLabel2: TQRLabel;
    QRDBText1: TQRDBText;
    QRDBText2: TQRDBText;
    QRDBText3: TQRDBText;
    QRDBText4: TQRDBText;
    QRLabel3: TQRLabel;
    QRLabel4: TQRLabel;
    QRLabel5: TQRLabel;
    QRLabel6: TQRLabel;
    QRLabel7: TQRLabel;

    PageFooterBand1: TQRBand;
    QRSysData2: TQRSysData;
    QRSysData3: TQRSysData;
  private

  public

  end;

var
  repLog: TrepLog;

implementation

uses loginDataModule;

{$R *.DFM}

end.


///主程序调用
procedure TViewLogForm.btnPrintClick(Sender: TObject);
var
     rep: TrepLog;
     str: string;
begin
     rep := TRepLog.Create(self);
     if FormatDateTime('yyyy',startdate) = '1900' then
           str := '(全部)'
     else
           str := '从 '+datetostr(startdate)+' 到 '+datetostr(enddate);
     rep.QRLabel2.Caption := '[时间段]'+str+'  [操作员] '+cbbUser.Text;
     rep.PreviewModal;
     rep.Free;
end;

你将QReport控件放在TQRpreview控件中来使用，在TQRpreview中添加打印按钮和其它翻页功能按钮，应该不会有问题。以下是我的一些代码，可以参考一下。
