我的问题已经解决了，现在贴出代码，再来4个人，就散分了。以下代码是在fastreport的代码页中写的，而且报表必须打开双通道

{
Text12.Visible=true;
Text13.Visible=true;
}
Page1.PaperHeight = (reportTitle1Height + pageHeader1Height+groupHeader1Height+data1Height+data2Height+groupFood1Height+pageFooter1Height)/Units.Millimeters+ Page1.TopMargin +Page1.BottomMargin;
}
}
//报表标题的高度
private void ReportTitle1_AfterLayout(object sender, EventArgs e)

reportTitle1Height=ReportTitle1.Height;

//页眉区的高度

//页脚区高度
