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

Exactly like what you said because that rdlc requires some sort of a dataSource :) It is a tricky issue in Report viewer and to solve it I wrote a method that will bind the report direct from Datatable:

private void GenerateReportDirect(ReportViewer reportViewer, string datasource, DataTable dt, string reportpath)
{
    reportViewer.LocalReport.ReportPath = reportpath;
    ReportDataSource repds = new ReportDataSource(datasource, dt);
    reportViewer.LocalReport.DataSources.Clear();
    reportViewer.LocalReport.DataSources.Add(repds);
    reportViewer.LocalReport.Refresh();
}

and to implement this method you have to specify putting the string of dataset table adapter just a name but our report will take the data to bind from the data table (we will cheat on our report viewer :) )

private void BindReport(DataTable dt)
    {
            string reportPath = Server.MapPath("StudentBus.rdlc");
            GenerateReportDirect(ReportViewer1, "StudentDataSet_usp_RPT_StudentBus", dt, reportPath);
    }

I hope this will help :) .
