.NET 2.0¶

public static void FromRdlcFile(string rdlcFileName, string dataSourceName, DataTable inputData, 
    HttpResponse response)
{
    //- Initialize Report Viewer Control ------------------------------------------------------
    ReportViewer rv = new ReportViewer();
    LocalReport r = rv.LocalReport;
    r.EnableExternalImages = true;
    r.ReportPath = "Reports/" + rdlcFileName;
    r.DataSources.Clear();
    ReportDataSource rds = new ReportDataSource(dataSourceName, inputData);
    r.DataSources.Add(rds);

    //- Render Report in PDF ------------------------------------------------------------------
    Warning[] warnings;
    string mimeType, encoding, fileNameExtension;
    string[] streams;

    byte[] bytes = r.Render("PDF", "", out mimeType, out encoding, out fileNameExtension, out 
                            streams, out warnings);

    int size = bytes.GetUpperBound(0) + 1;

    char[] c = new char[size];

    bytes.CopyTo(c, 0);

    //- Write PDF Contents to HTTP Response ---------------------------------------------------
    //response.Clear();
    response.ContentType = "Application/pdf";
    response.Write(c, 0, size);
    response.End();
}

.NET 4.0¶

Local Report Processing¶

private void RenderAsPdf(string rdlcFileName, string dataSourceName, DataTable 
    inputData, HttpResponse response)
{
    //- Initialize Report Viewer Control --------------------------------------------------
    ReportViewer rv = new ReportViewer();
    LocalReport r = rv.LocalReport;
    r.EnableExternalImages = true;
    r.ReportPath = "Reports/" + rdlcFileName + ".rdlc";
    r.DataSources.Clear();
    ReportDataSource rds = new ReportDataSource(dataSourceName, inputData);
    r.DataSources.Add(rds);

    //- Render Report in PDF --------------------------------------------------------------
    Warning[] warnings;
    string mimeType, encoding, fileNameExtension;
    string[] streams;

    byte[] bytes = r.Render("PDF", null, out mimeType, out encoding, out fileNameExtension,  
                            out streams, out warnings);

    int size = bytes.GetUpperBound(0) + 1;

    char[] c = new char[size];

    bytes.CopyTo(c, 0);

    //- Write PDF Contents to HTTP Response -----------------------------------------------
    response.Buffer = true;
    response.Clear();
    response.ContentType = mimeType;
    response.AddHeader("content-disposition", "attachment; filename=" + rdlcFileName + "." 
        + fileNameExtension);
    response.BinaryWrite(bytes);
    response.Flush();
    response.End();
}

Server Report Processing¶

Note: the following code can be a controller method.

public void GetMyReportPdf(int id)
{
    //- Inits -----------------------------------------------------------------------------
    var orderID = id;
    var reportName = "Order";
    var rv = new ReportViewer();
    var rpt = rv.ServerReport;

    //- Configure ReportViewer Control ----------------------------------------------------
    rv.ShowCredentialPrompts = false;
    rv.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;

    //- Configure ServerReport ------------------------------------------------------------
    var config = Acme.Configuration.AcmeConfiguration.Settings.Ssrs;

    if (!config.DefaultCredentials)
        rpt.ReportServerCredentials = new ReportServerCredentials(config);

    rpt.ReportServerUrl = config.ReportServerUrl; /* URL of SSRS web service*/
    rpt.ReportPath = config.RootPathWithSlashes + reportName;

    //- Set LoginName Parameter (?) -------------------------------------------------------
    var p = rpt.GetParameters()["OrderID"];

    if (p != null)
    {
        var p2 = new ReportParameter("OrderID", orderID.ToString());
        rpt.SetParameters(p2);
    }

    //- Render Report in PDF --------------------------------------------------------------
    Warning[] warnings;
    string mimeType, encoding, fileNameExtension;
    string[] streams;

    byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out fileNameExtension,
                            out streams, out warnings);

    int size = bytes.GetUpperBound(0) + 1;

    char[] c = new char[size];

    bytes.CopyTo(c, 0);

    //- Write PDF Contents to HTTP Response -----------------------------------------------
    var response = System.Web.HttpContext.Current.Response;
    response.Buffer = true;
    response.Clear();
    response.ContentType = mimeType;
    response.AddHeader("content-disposition", "attachment; filename=" + reportName + "."
        + fileNameExtension);
    response.BinaryWrite(bytes);
    response.Flush();
    response.End();
