100分求组个关于打印的问题

Question

我需要的内容是这样的。点击打印出现打印预览，不要用excel预览，因为excel预览内容可以改变，我要的预览只能看，不能改。然后点击打印才打印预览内容，能有打印设置最好。 
哪位高手把源代码贴出来啊，公司急要

用水晶報表，然後導成pdf檔. protected void btn_Pdf_Click(object sender, EventArgs e)//導pdf代碼
    {
        try
        {
            //記錄打印次數
              Getsource();//數據綁定
            Response.ClearContent();
            Response.ClearHeaders();
            Response.Clear();
            Response.ContentType = "application/pdf";
            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=Ebook.pdf");
            Stream stream = reportDoc.ExportToStream(ExportFormatType.PortableDocFormat);
            byte[] dataArray = new byte[stream.Length];
            stream.Read(dataArray, 0, Convert.ToInt32(stream.Length));
            Response.BinaryWrite(dataArray);
            Response.Flush();
            Response.Close();
            reportDoc.Close();
            reportDoc.Dispose();
        }
        catch (Exception ex)
        {
            System.Windows.Forms.MessageBox.Show("文件導出失敗");
            return;        }    }
 
private void Getsource()//水晶報表綁定數據源
    {
              reportDoc = new ReportDocument();
              reportDoc.Load(Server.MapPath("../REPORT/rpt_Wstb.rpt"));
reportDoc.SetDataSource(SqlHaper.GetDataSet(str_Sql));//  SqlHaper.GetDataSet(str_Sql)這裡是取得一個dataview給數據
                reportDoc.ParameterFields["z001"].CurrentValues.AddValue(str_Par1);
                reportDoc.ParameterFields["zd001"].CurrentValues.AddValue(str_creatUser);
                reportDoc.ParameterFields["z002"].CurrentValues.AddValue(str_Par2);
                reportDoc.ParameterFields["d1"].CurrentValues.AddValue(str_Par3);
                reportDoc.ParameterFields["d2"].CurrentValues.AddValue(str_Par4);
                reportDoc.ParameterFields["s001"].CurrentValues.AddValue(str_Sding);
                CrystalReportViewer1.ReportSource = reportDoc;
                CrystalReportViewer1.DataBind();
}
