I'm using the following code trying to SetParametr :
C#
var report = new ReportParameter[1];
   report[0] = new ReportParameter("MyName", "Raha");
   var reportDataSource1 = new ReportDataSource { Name = "WpfApplication17_User", Value = _users };
   _reportViewer.LocalReport.DataSources.Add(reportDataSource1);
   _reportViewer.ServerReport.SetParameters(report);
   _reportViewer.LocalReport.ReportPath = "../../Report1.rdlc";
   _reportViewer.RefreshReport();

error : The source of the report definition has not been specified

Why wrong?

I've created a report parameter , Parameter name is 'MyName'

I'm using the following code :
C#
//var report = new ReportParameter[1];
   //report[0] = new ReportParameter("MyName", "Raha");
   var reportDataSource1 = new ReportDataSource { Name = "WpfApplication17_User", Value = _users };
   string exeFolder = System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName);
   _reportViewer.LocalReport.ReportPath =exeFolder + @"\Reports\Report1.rdlc";
   _reportViewer.LocalReport.DataSources.Add(reportDataSource1);
   //_reportViewer.ServerReport.SetParameters(report);
   _reportViewer.RefreshReport();

data displayed in Report.

but , I'm using the following code :
C#
var report = new ReportParameter[1];
           report[0] = new ReportParameter("MyName", "Raha");
           var reportDataSource1 = new ReportDataSource { Name = "WpfApplication17_User", Value = _users };
           string exeFolder = System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName);
           _reportViewer.LocalReport.ReportPath = exeFolder + @"\Reports\Report1.rdlc";
           _reportViewer.LocalReport.DataSources.Add(reportDataSource1);
           _reportViewer.ServerReport.SetParameters(report);//error
           _reportViewer.RefreshReport();

error as : The source of the report definition has not been specified

how can i download report properly

Hi. I had the same error and the problem was with NULL values from SQL.
Check if you have null values in your SQL result. I  lost two days searching for what is not ok with "The report definition for report '' has not been specified".
