            this.rptviewer.ShowNextPage();
        }


private void BindReport()
        {
            if (Session["Rep"] == null)
            {
                Hashtable Params = new Hashtable();
                Params.Add("StartDate", Convert.ToDateTime(this.StartDateFlexDevCalendar.GetDate));
                Params.Add("EndDate", Convert.ToDateTime(this.EndDateFlexDevCalendar.GetDate));

                report = new ReportDocument();
                report.Load(Server.MapPath("EN/" + reportName ));


                TableLogOnInfos tblLogonInfos = new TableLogOnInfos();
                TableLogOnInfo tblLogonInfo = new TableLogOnInfo();
                ConnectionInfo connectionInfo = new ConnectionInfo();

                connectionInfo.ServerName = "sokheng";
                connectionInfo.UserID = "sa";
                connectionInfo.Password = "1234";
                connectionInfo.DatabaseName = "DatabaseABC";


                foreach (CrystalDecisions.CrystalReports.Engine.Table tbl in report.Database.Tables)
                {
                    tblLogonInfo = tbl.LogOnInfo;
                    tblLogonInfo.ConnectionInfo = connectionInfo;
                    tbl.ApplyLogOnInfo(tblLogonInfo);
                }

                if (Params != null)
                {
                    foreach (DictionaryEntry p in Params)
                    {
                        report.SetParameterValue(Convert.ToString(p.Key), Convert.ToDateTime(p.Value));
                    }
                }
                Session["Rep"] = report;
            }
            report = (ReportDocument)Session["Rep"];
            this.rptviewer.ReportSource = report;
            this.rptviewer.DataBind();
        }

因此，请帮助我...解决该问题该怎么办?

推荐答案

Crystal Reports查看器内置了工具栏，其中包含用于浏览报表的按钮.在这里说明

The crystal reports viewer has built in toolbar which contains the buttons to navigate the report as explained here

我遇到了同样的问题，并将报告加载代码移至page_init
