I'm working with Asp.net MVC 4.

I have this snippet:

var data = // fill my data.
var rds = new ReportDataSource("MyDataset", data);

var viewer = new ReportViewer();

viewer.LocalReport.Refresh();
viewer.LocalReport.DataSources.Clear();
viewer.LocalReport.DataSources.Add(rds);
viewer.LocalReport.ReportPath = @"Reports/Report1.rdlc";

string mimeType, encoding, extension;
string[] streamids;
Warning[] warnings;

var buffer = viewer.ServerReport.Render("PDF", "C:", out mimeType, out encoding, out extension, out streamids, out warnings);

But the method Render throw a exception:

Microsoft.Reporting.WebForms.MissingReportSourceException: The source of the report definition has not been specified.

I'm search and found: this 1, this 2, this 3 and others.

Using these links I tried:

Try 1: 

viewer.LocalReport.ReportPath = @"../Reports/Report1.rdlc";

Try 2:

viewer.LocalReport.ReportPath = @"../../Reports/Report1.rdlc";

Try 3:

viewer.LocalReport.ReportPath = @"~/Reports/Report1.rdlc";

Try 4:

viewer.LocalReport.ReportPath = Server.MapPath(@"~/Reports/Report1.rdlc");

Try 5:

var fileName = Server.MapPath(@"~/Reports/Report1.rdlc");
using (var fs = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
    viewer.LocalReport.LoadReportDefinition(fs);
}

However all these attempts throw the same exception.

Anyone has some idea? I'm several hours trying to make it work.

Please make sure that you have either used one of the following when using 

reportViewer1.LocalReport.ReportPath = @"path/reportName.rdlc"

scenario when report is located other than bin folder of debug or release

or you can use 

reportViewer1.LocalReport.ReportPath = @"reportName.rdlc"

when its at application.StartupPath

Try this:

var data = // fill my data.
var rds = new ReportDataSource("MyDataset", data);

var viewer = new ReportViewer();

viewer.LocalReport.Refresh();
viewer.LocalReport.DataSources.Clear();
viewer.LocalReport.DataSources.Add(rds);




            string fileName=  "Reports/Report1.rdlc";

        FileStream S = new FileStream(Server.MapPath(fileName), FileMode.Open);
        viewer.LocalReport.LoadReportDefinition(S);
        S.Close();

string mimeType, encoding, extension;
string[] streamids;
Warning[] warnings;

var buffer = viewer.ServerReport.Render("PDF", "C:", out mimeType, out encoding, out extension, out streamids, out warnings);
