Question

我正在开发一个WPF应用程序，我使用包含一个图表的ReportViewer，但我需要在报告中显示另一个图表。我创建了一个子报表，并在我的主报表中调用它。但是，如果我在子报表中插入图表不起作用！ The Subreport1 could not be found at the specified location. Please verify that the subreport has been published and that the name is correct. 如果我使用表格或文本框，它可以工作但不是图表。这是我的代码Behind：

private void showReport(object sender, RoutedEventArgs e)
        {



            RVInfoGrafico.Reset();
            RVInfoGrafico.LocalReport.DataSources.Clear();
            RVInfoGrafico.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(MSubreportProcessingEventHandler);

            DataTable dt = GetData2();
            ReportDataSource rds = new ReportDataSource("DataSet1", dt);

            RVInfoGrafico.LocalReport.DataSources.Add(rds);
            RVInfoGrafico.LocalReport.ReportEmbeddedResource = "Project.Info.rdlc";
            RVInfoGrafico.ProcessingMode = ProcessingMode.Local;
            RVInfoGrafico.RefreshReport();

        }
        void MSubreportProcessingEventHandler(object sender, SubreportProcessingEventArgs e)
        {
            DataTable dt9 = GetData4();
            e.DataSources.Add(new ReportDataSource("DataSet1",dt9));
        }

错误表明它无法找到Subreport1。也许尝试使用LoadSubreportDefinition直接提供它（＆＃34; Subreport1＆＃34;，xxx）？

这样的事情：

var asm = Assembly.GetExecutingAssembly();
var stream = asm.GetManifestResourceStream("RVInfoGrafico.Reports.Subreport.rdlc"); // Change to your path or get a stream of it some other way
RVInfoGrafico.LocalReport.LoadSubreportDefinition("Subreport1", stream);

仅供参考 - 在我完成此项目的项目中，.rdlc文件＆＃39; VisualStudio中的Build Action设置为＆＃34; Embedded Resource＆＃34;。
