Crystal Report Viewer Export&打印按钮在VS 2010中不起作用 [英] Crystal Report Viewer Export & Print buttons are not working in VS 2010

问题描述

大家好，

最后一天，我认为我搜索了所有bolg网站以获得解决方案，但是我得到它的解决方案对我来说不起作用。但我今天必须完成它。



=====================

信息：



CR Dev版本：13.0.2.469

CR Runtime Engine for .net 4.0 version：13.0.2.469

操作系统：XP 32位

VS：2010

===================== ===

打印和导出按钮适用于以下代码：

---------------------- --------------------------

String Report = string.Empty;

protected void Page_Load（object sender，EventArgs e）

{

Report = Request.QueryString [ReportName];





ReportDocument rptDoc = new ReportDocument（）;

dsATS ds = new dsATS（）; // .xsd文件名

DataTable dt = new DataTable（）;





//只需设置数据表的名称

dt.TableName =报告;

dt = getAllOrders（）; //这个函数位于这个函数下面

ds.Tables [0] .Merge（dt）;







//您的.rpt文件路径将低于

if（Report ==RefundSummaryReport）

{

rptDoc.Load（Server.MapPath（〜/ Reports / crtRefundSummaryReport.rpt））;

}



//将数据集设置为报表查看器。

rptDoc.SetDataSource（ds）;

CrystalReportViewerATS.ReportSource = rptDoc;

推荐答案

如果我评论

if (!IsPostBack)

那么它工作正常。

then it working fine.

//if (!IsPostBack)
            //{
                string reportName = Request.QueryString["ReportName"];
                string assemblyName = ConfigurationManager.AppSettings["ATSReports"];
                DataTable dt = new DataTable();

                reportData = FindRunTimeObject<IReportData>.CreateReportController(assemblyName, reportName + "Data") as IReportData; //new AssessmentsTaxTypeReportData();
                List<Object> parametersList = (List<Object>)Session["ListParameters"];
                SqlDataReader dr = reportData.GetReportOutputData(parametersList) as SqlDataReader;
                ReportClass report = FindRunTimeObject<ReportClass>.CreateReportController(assemblyName, reportName) as ReportClass;

                ParameterFields crvParameters = reportData.ReturnReportParameters(parametersList) as ParameterFields;

                report.Load(reportName + ".rpt");
                dt.Load(dr);
                report.SetDataSource(dt);
                CrystalReportViewer_RV.ReportSource = report;
                CrystalReportViewer_RV.ParameterFieldInfo = crvParameters;
