The report definition for report 'ABC.rdlc' has not been specified

Question

Hi all,

I've recently moved my RDLC files into the class library (as I'm going to be having multiple "UI" projects accessing the same reports). So as I moved them to the class library and set them as Embedded Resources I changed the binding of the report viewer to:

Microsoft.Reporting.WebForms.ReportDataSource rdsAPI = new Microsoft.Reporting.WebForms.ReportDataSource("DS1", ds1 as System.Data.DataTable);
Microsoft.Reporting.WebForms.ReportDataSource rdsUser = new Microsoft.Reporting.WebForms.ReportDataSource("UserDS", user as System.Data.DataTable);

ReportHelper.SetReportEmbeddedResource(rvds1Pdf, "ClassLibrary1.Namespace.Blah.ds1.rdlc");
rvds1Pdf.LocalReport.DataSources.Add(rdsds1);
rvds1Pdf.LocalReport.DataSources.Add(rdsUser);
rvds1Pdf.Visible = true;
byte[] reportData = rvds1Pdf.LocalReport.Render("PDF");
rvds1Pdf.Visible = false;

The ReportHelper.SetReportEmbeddedResource method is inside the same class library as the RDLC because that's the only way I've found it to work and all it does is this:

public static void SetReportEmbeddedResource(Microsoft.Reporting.WebForms.ReportViewer reportViewer, string reportName)
{
            reportViewer.LocalReport.ReportEmbeddedResource = reportName;
}

All works perfectly until I deploy it to the UAT box. Then I receive "The report definition for report 'ClassLibrary1.Namespace.Blah.ds1.rdlc' has not been specified"!

I used http://www.codeproject.com/Articles/3262/A-NET-assembly-viewer to double check that the RDLC is present as a Manifest Resource inside the DLL that's on the UAT box, which it is. So I'm a bit stumped why this is happening. I'm using a box standard web deployment project package the web site.

Any thoughts/suggestions?

Kind regards

Some more information about this. Locally I was using the built-in Cassini/VS Web server however on UAT I'm using IIS. I changed my local settings to use IIS and I get the same error!

Any suggestions on what I can try or which IIS setting might cause this error?

Kind regards

Answer 2

Okay, I think I have fixed the problem with the embedded report. I changed the SetReportEmbeddedResource method to:

public static void SetReportEmbeddedResource(Microsoft.Reporting.WebForms.ReportViewer reportViewer, string reportName)
{
    using (Stream s = Assembly.GetExecutingAssembly().GetManifestResourceStream(reportName))
    {
        reportViewer.LocalReport.LoadReportDefinition(s);
    }
}

Kind regards

Thanks, this helped me.

For me, I was only getting the error when a) under full IIS (not IIS Express) AND b) compiled under Release configuration.

I think it was working on the production machine for a time without this fix, and I'm not sure what changed. I'm guessing something to do with DLL load order. Anyway, implementing your code change makes this much more reliable.

Notes: this was Report Viewer 2012 on Win7 dev machine and SBS 2008 server, under IIS, using .NET 4.5. Full error text:

An error occurred during local report processing.
The report definition for report 'XReport' has not been specified
Object reference not set to an instance of an object.
