使用方法：


private static clsPrint m_clsPrint = new clsPrint();

  private void Page_Load(object sender, System.EventArgs e)
  {
   if(!IsPostBack)
   {  
       BindGrid();
   }
  }


private void DisplayGrid()
{


MyDataGrid.DataBind();
m_clsPrint.dgDataGrid = MyDataGrid;


}


private void btnPrint_Click(object sender, System.EventArgs e)
{
   可使用方法和属性如下：

   m_clsPrint.PageTitle = "权限列表";
   m_clsPrint.PageNumber = 30;

   string[] sShoulderLeft = new string[3];
   string[] sShoulderCenter = new string[1];
   string[] sShoulderRight = new string[2];

   sShoulderLeft[0] = "左页眉一";
   sShoulderLeft[1] = "左页眉二";
   sShoulderLeft[2] = "左页眉三";

   sShoulderCenter[0] = "中页眉一 ";

   sShoulderRight[0] = "右页眉一";
   sShoulderRight[1] = "右页眉二（共计XXXX名）";

   m_clsPrint.ShoulderLeft = sShoulderLeft;
   m_clsPrint.ShoulderCenter = sShoulderCenter;
   m_clsPrint.ShoulderRight = sShoulderRight;

   string[] sFooterLeft = new string[3];
   string[] sFooterCenter = new string[1];
   string[] sFooterRight = new string[2];

   sFooterLeft[0] = "左页脚一制表人：XXX 制表日期：";
   sFooterLeft[1] = "左页脚二复核人：XXX 复核日期：";
   sFooterLeft[2] = "左页脚三XXX教学服务站（中心）XXXX入学年级";

   sFooterCenter[0] = "中页脚一";

   sFooterRight[0] = "右页脚一2009年18月40";
   sFooterRight[1] = "右页脚二（共计XXXX名）";

   m_clsPrint.FooterLeft = sFooterLeft;
   m_clsPrint.FooterCenter = sFooterCenter;
   m_clsPrint.FooterRight = sFooterRight;
   m_clsPrint.SpanColumnList="0,1";



   m_clsPrint.PrintView();



   Page.RegisterStartupScript("show", "<script languge='javascript'>window.open('"+PageBase.UrlBase+"/printWindow.htm','_blank');</script>");


  }


其中：PageBase.UrlBase是自己定义的返回的当前站点的URL
