Set Parameters RDLC Report C#

Question

In my rdlc report I create parameter test. In form I write below code to set parameter:

//Set Parameters
ReportParameter[] p = new ReportParameter[1];
p[0] = new ReportParameter("Test", "Testing");
currentBilling_rv.LocalReport.SetParameters(p);

// Provide datasource to report Current_Total_Billing.rdlc
ReportDataSource rds = new ReportDataSource("CurrentTotalBilling", dataset.Tables[2]);
currentTotalBilling_rv.LocalReport.DataSources.Clear();
currentTotalBilling_rv.LocalReport.DisplayName = "Current Total Billing";
currentTotalBilling_rv.LocalReport.ReportPath = ".\\Current_Total_Billing.rdlc";
currentTotalBilling_rv.LocalReport.DataSources.Add(rds);
currentTotalBilling_rv.RefreshReport();

When I run the program I have exception

An unhandled exception of type 'Microsoft.Reporting.WinForms.MissingReportSourceException' occurred in Microsoft.ReportViewer.WinForms.dll

Additional information: The source of the report definition has not been specified

Please help.

Answer 1

In your code you are setting a parameter for a ReportViewer named currentBilling_rv not for currentTotalBilling_rv which is used in the next lines of code.

If currentBilling_rv name is correct verify that currentBilling_rv.LocalReport.ReportPath is compiled.
