Where's the part where you "bind to a data source"?

Hi There,

I may be mistaken, but .rdl files belong to SQL Reporting Services (SSRS), and ReportViewer is the winforms/webforms control that handles .rdlc files. Your code sample seems to belong to a webform.

Having mentioned that, most of the required code for both winforms/webforms is basically the same, but there are some minor differences that must not be ignored.

Webform example(rptVwr is the name I gave to the ReportViewer control):

DataSet ds = Your method to get the required data;

            rptVwr.ProcessingMode = ProcessingMode.Local;
            rptVwr.LocalReport.EnableExternalImages = true;
            rptVwr.LocalReport.ReportPath = "Reports/DTE.rdlc";
            rptVwr.LocalReport.DataSources.Clear();
            rptVwr.LocalReport.DataSources.Add(new ReportDataSource("Dcto", ds.Tables[0]));
            rptVwr.LocalReport.DataSources.Add(new ReportDataSource("Events", ds.Tables[1]));
            rptVwr.LocalReport.DataSources.Add(new ReportDataSource("AuxData", ds.Tables[2]));
            rptVwr.LocalReport.Refresh();

Winforms Example (RepVwer is the name I gave to the ReportViewer control):

... DataSet ds = here goes your method to get the required data;

RepVwer.ProcessingMode = ProcessingMode.Local;
                RepVwer.LocalReport.ReportEmbeddedResource = "DTEViewer.rdlc.DTE.rdlc";

                RepVwer.LocalReport.DataSources.Clear();
                RepVwer.LocalReport.DataSources.Add(new ReportDataSource("IdDoc", ds.Tables[0]));
                RepVwer.LocalReport.DataSources.Add(new ReportDataSource("Emi", ds.Tables[1]));
                RepVwer.LocalReport.DataSources.Add(new ReportDataSource("Recep", ds.Tables[2]));
                RepVwer.LocalReport.DataSources.Add(new ReportDataSource("Details", ds.Tables[3]));
                RepVwer.LocalReport.DataSources.Add(new ReportDataSource("Totals", ds.Tables[4]));
                this.RepVwer.RefreshReport();

If your need to pass parameters to a report, create the array, assign all needed values, and add it to the report:

ReportParameter[] repParams = new ReportParameter[3];
repParams[0] = new ReportParameter("MyParam1", "false");
repParams[1] = new ReportParameter("MyParam2", nroOper);
repParams[2] = new ReportParameter("MyParam3", "blah, blah, blah!");
LocReport.LocalReport.SetParameters(repParams);

That's how I configure ReportViewer controls, assign the report to use, bind data, and finally display them.

Hope this helps; cheers!
