Add Subreport with Stream

[Imperator]

Hi,

I'm trying to add a Subreport dynamically via a Stream.

I've tryed to call the method LoadSubreport directly after the LoadReport Method.

But it's not working. Every time I get this error message: "An error occurred while rendering 'SubReport' report item."

If I render the SubReport as a normal report it works.

In the path-field of the subreport control I've set the same text i pass through the LoadSubReport method

What am I doing wrong?

Can you please provide me with an example project?

Thx

Hi Stefan, 

 

We have validated the mention query with your shared details at our end. Please find the following code snippet to load subreport from stream, 

 

private void MainWindow_Loaded(object sender, RoutedEventArgs e) 

{ 

    viewer.ProcessingMode = ProcessingMode.Local; 

    Assembly assembly = typeof(MainWindow).GetTypeInfo().Assembly; 

    Stream reportStream = assembly.GetManifestResourceStream("ReportViewer.Reports.MainReport.rdlc"); 

    Stream subReportStream = assembly.GetManifestResourceStream("ReportViewer.Reports.SubReport.rdlc"); 

    viewer.SubreportProcessing += Viewer_SubreportProcessing; 

    viewer.LoadSubreport("SubReport", subReportStream); 

    viewer.LoadReport(reportStream); 

    viewer.DataSources.Clear(); 

    viewer.DataSources.Add(new Syncfusion.Windows.Reports.ReportDataSource("TopSalesPerson", SalesPersons.GetTopSalesPerson()));    

    viewer.RefreshReport(); 

} 

private void Viewer_SubreportProcessing(object sender, Syncfusion.Windows.Reports.SubreportProcessingEventArgs e) 

{ 

    e.DataSources.Clear(); 

    e.DataSources.Add(new Syncfusion.Windows.Reports.ReportDataSource("StoreSales", StoreSales.GetData())); 

} 

 

We have created standalone sample to load subreport from the stream and it can be downloaded from the following location,
