推荐答案

试试这个:

protected void Page_Load(object sender, EventArgs e) 
{ 

If (!IsPostBack)
{ 
    Title = "عرض التقارير"; 
    if (Session["UserCode"] == null) Response.Redirect("~/Login.aspx");  

    if (Request.QueryString["id"] != null) 
    { 
        oReport = new Cls_Report(); 
        oReportDocument = new ReportDocument(); 

        if (!Session["Condition"].Equals(null)) 
        { 
            oReport.Condition = Session["Condition"].ToString(); 
            Session.Remove("Condition"); 
        } 

        switch (Request.QueryString["id"]) 
        { 

            case "1": 
                oReportDocument.Load(Server.MapPath("~/reports/ar1.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAllEmployees(false)); 
                break; 

            case "2": 
                oReportDocument.Load(Server.MapPath("~/reports/ar2.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAlljpbs()); 
                break; 

            case "1order": 
                oReportDocument.Load(Server.MapPath("~/reports/ar1.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAllEmployees(true)); 
                break; 
            case "3": 
                oReportDocument.Load(Server.MapPath("~/reports/ar3.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAlljudges()); 
                break; 
            case "4": 
                oReportDocument.Load(Server.MapPath("~/reports/ar4.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAlljudgesindestrict()); 
                break; 
             case "5": 
                oReportDocument.Load(Server.MapPath("~/reports/ar5.rpt")); 
                oReportDocument.SetDataSource(oReport.ReportAlljudgesRank()); 
                break; 

        } 
        ReportViewer.ReportSource = oReportDocument;
        Session["myReport"] = oReportDocument;
    } 
}
else
{
    ReportViewer.ReportSource = (ReportDocument)Session["oReportDocument"];
}

}
