asp.net – VS2012 Crystal Report Viewer组树隐藏

我想隐藏/禁用包含组树按钮的L.H.窗格.

DisplayGroupTree属性标记为已过时且无效.

我设置了ToolPanelView =“None”也没有效果.

隐藏组树问题已经存在于早期版本中,但是根据我的意见,已发布的答案不起作用或转换为此版本.

也许我正在构建错误的报告. (显示OK).

private void ShowReport(MyClassLibrary.Report report)

        cn.ServerName = "MyServer";
        cn.DatabaseName = "MyDatabase";
        cn.UserID = "myUser";
        cn.Password = "myPassword";
        string reportDirectory = Server.MapPath(".") + "Reports";
        CrystalReportSource rs = new CrystalReportSource();
        Session["CurrentReportSource"] = rs;
        CrystalDecisions.Web.Report r = new CrystalDecisions.Web.Report();


        r.FileName = reportDirectory + report.reportPath;
        rs.Report = r;

        CRV.ReportSource = rs;

        pUserId.CurrentValues.Add(pUserIdValue);

        p.Add(pUserId);
        p.Add(pStartDate);
        p.Add(pEndDate);

        }


        rs.DataBind();
    }
