I'm getting “The report definition for report 'xxxx.rdlc' has not been specified” in my RDLC report

Question

I\'ve created an rdlc report. I have a reportViewer on my form. When I try to load the report I get : \"The report definition for report \'xxxx.rdlc\' has not been specifie

Answer 1

There are some reasons causing this problem and sometimes the problem might occur only when publishing the same application to IIS. If the report file (*.rdlc) is existed in the related location and the problem still continues, you can try the following methods in order to fix it:

from LocalReport.ReportEmbeddedResource Property on MSDN
“… An embedded report resource is a report definition that has been stored as a resource in the calling assembly. If the ReportPath property has been set, the ReportEmbeddedResource property is ignored. It also causes the report loaded with LoadReportDefinition to be ignored.”

Change:

reportViewer.LocalReport.ReportPath = Server.MapPath("~/Reporting/YourReportName.rdlc");

to:

rw.LocalReport.ReportEmbeddedResource = "YourFullNamespace.Reporting.YourReportName.rdlc";

And then change Build Action property to Embedded Resource from the properties of YourReportName.rdlc file. Hope this helps...
