在VS2012平台用reportviewer做报表，报表加载后，页面一直显示“正在加载”，调试，发现代码进入死循环，不停执行非IspostBack中的代码：
if (!IsPostBack) { if (Master != null) { //控件注册 var scriptManager = Master.FindControl("ReportSM") as ScriptManager; if (scriptManager != null) { scriptManager.RegisterAsyncPostBackControl(this.btn_submit); } if (reportViewer != null) { string filepath = HttpContext.Current.Server.MapPath("" + AppPath + "/ReportModel/" + reportInfo.RdlcName); reportViewer.LocalReport.ReportPath = filepath; ReportDataSource rds = new ReportDataSource("DataSet1", dt); reportViewer.LocalReport.DataSources.Clear(); reportViewer.LocalReport.DataSources.Add(rds); ReportParameter[] parameterArray = SetReportStyle(); ReportParameter p = new ReportParameter("ReportName", reportInfo.Title); parameterArray[42] = p; p = new ReportParameter("ReportTitle", reportInfo.Subtitle); parameterArray[43] = p; p = new ReportParameter("ReportLHead", "统计日期："); parameterArray[44] = p; p = new ReportParameter("ReportMHead", ""); parameterArray[45] = p; p = new ReportParameter("ReportRHead", ""); parameterArray[46] = p; p = new ReportParameter("ReportLFoot", ""); parameterArray[47] = p; p = new ReportParameter("ReportMFoot", ""); parameterArray[48] = p; p = new ReportParameter("ReportRFoot", ""); parameterArray[49] = p; reportViewer.LocalReport.SetParameters(parameterArray); reportViewer.LocalReport.Refresh(); } } } else { var value = Request.Form["startDate"]; if (reportViewer != null) { ReportParameter p = new ReportParameter("ReportLHead", "统计日期：" + value); reportViewer.LocalReport.SetParameters(p); reportViewer.LocalReport.Refresh(); } }
求高手指点,这种问题该怎解决呢？

你把这句
reportViewer.LocalReport.Refresh();
去掉看看。
我试过的，不起作用........

你if的那些括号， 是不是错了。
那个没有错

先设置报表参数，再加载报表试试！
ReportParameter[] parameterArray = SetReportStyle(); ReportParameter p = new ReportParameter("ReportName", reportInfo.Title); parameterArray[42] = p; p = new ReportParameter("ReportTitle", reportInfo.Subtitle); parameterArray[43] = p; p = new ReportParameter("ReportLHead", "统计日期："); parameterArray[44] = p; p = new ReportParameter("ReportMHead", ""); parameterArray[45] = p; p = new ReportParameter("ReportRHead", ""); parameterArray[46] = p; p = new ReportParameter("ReportLFoot", ""); parameterArray[47] = p; p = new ReportParameter("ReportMFoot", ""); parameterArray[48] = p; p = new ReportParameter("ReportRFoot", ""); parameterArray[49] = p; reportViewer.LocalReport.SetParameters(parameterArray);
放在
ReportDataSource rds = new ReportDataSource("DataSet1", dt); reportViewer.LocalReport.DataSources.Clear(); reportViewer.LocalReport.DataSources.Add(rds);
前面试试！
