I am facing below error while rendering PDF report on ReportViewer.
Below is the code causing this issue:
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;
string extension = string.Empty;
byte[] bytes = ReportViewer1.ServerReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "inline; filename=myfile");
Response.BinaryWrite(bytes);
Response.Flush();
The fix that worked for me was to add the below line of code at the end.
Response.End();
I'm doing a basic MVC apps and i'm trying to export the value of my SQL query to an Excel.
When i open the Excel file the 2 fields that are part of the JOIN are empty and i dont undertand why since when i click on Preview data on my DataSet i see the correct result.
But in my Excel file i dont see the TitleDescription and the TeamDescription.
My SQL Query:
Select Emp.EmployeeID, Emp.FirstName, Emp.LastName, Ti.TitleDescription, Te.TeamDescription,
Emp.Phone FROM Employees Emp
JOIN Titles Ti ON Emp.TitleID=Ti.TitleID
JOIN Teams Te ON Emp.TeamID=Te.TeamID
My Method:
public ActionResult Reports(string ReportType)
{
LocalReport localreport = new LocalReport();
localreport.ReportPath = Server.MapPath("~/Reports/EmployeeReport.rdlc");
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Name = "EmployeeReportDataSet";
reportDataSource.Value = db.Employees.ToList();
localreport.DataSources.Add(reportDataSource);
string mimeType;
string encoding;
string fileNameExtension = "XLSX";
string[] streams;
Warning[] warnings;
byte[] renderedByte;
renderedByte = localreport.Render("EXCELOPENXML", null, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
Response.AddHeader("content-disposition", "attachment; filename=employee_report." + fileNameExtension);
return File(renderedByte, fileNameExtension);
}
I believe my problem is comming from reportDataSource.Value = db.Employees.ToList(); i should use DataTable1 instead of Employees but i'm not sure how.
I would really appreciate if someone can help me out.
Thanks,
I found what was the problem,
First i used a DataSet TableAdapter instead of the a DataSet Query and i used the method that was generated by default which is the GetData() method. I put it in the DataSource.Value=
Here's my corrected code:
public ActionResult Reports(string ReportType)
{
EmployeeReportDataSet employeeReportDataSet = new EmployeeReportDataSet();
EmployeeReportDataSetTableAdapters.TempReportTableAdapter employeereportTableAdapter =
new EmployeeReportDataSetTableAdapters.EmployeesReportsTableAdapter();
employeereportTableAdapter.Fill(employeeReportDataSet.TempReport);
LocalReport localreport = new LocalReport();
localreport.ReportPath = Server.MapPath("~/Reports/EmployeeReport.rdlc");
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Name = "EmployeeReportDataSet";
reportDataSource.Value = employeereportTableAdapter.GetData();
localreport.DataSources.Add(reportDataSource);
string mimeType;
string encoding;
string fileNameExtension = "XLSX";
string[] streams;
Warning[] warnings;
byte[] renderedByte;
renderedByte = localreport.Render("EXCELOPENXML", null, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
Response.AddHeader("content-disposition", "attachment; filename=employee_report." + fileNameExtension);
return File(renderedByte, fileNameExtension);
}

I am facing problem in last two days. I am trying to view rdlc report as pdf without reportviewer. I export rdlc to pdf using the following code...
public string Export(LocalReport rpt, string filePath)
{
string ack = "";
try
{
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
using (FileStream stream = File.OpenWrite(filePath))
{
stream.Write(bytes, 0, bytes.Length);
}
return ack;
}
catch(Exception ex)
{
ack = ex.InnerException.Message;
return ack;
}
}
The pdf file exported to User->AppData->Temp
string filePath = System.IO.Path.GetTempFileName();
string ack = Export(rpt, Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc"));
System.Diagnostics.Process.Start(filePath);
I want to render this pdf file to the client PC.
This Code is work fine on my local machine. But when i publish this to IIS Server and run for try to get the exported pdf file to client PC not success. How can i solve this issue. Can anyone help me.
Thanks In Advance...
Finally, i found one solution about view RDLC report as pdf in asp.net MVC. The solution is following....
public FileResult ViewReport()
{
string RptPath = Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc");
Microsoft.Reporting.WebForms.LocalReport rpt = new Microsoft.Reporting.WebForms.LocalReport();
/* Bind Here Report Data Set */
rpt.ReportPath = RptPath;
string filePath = System.IO.Path.GetTempFileName();
Export(rpt, filePath);
//CLOSE REPORT OBJECT
rpt.Dispose();
return File(filePath, "application/pdf");
}
I use the following method for generate pdf from RDLC....
public string Export(LocalReport rpt, string filePath)
{
string ack = "";
try
{
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
using (FileStream stream = File.OpenWrite(filePath))
{
stream.Write(bytes, 0, bytes.Length);
}
return ack;
}
catch(Exception ex)
{
ack = ex.InnerException.Message;
return ack;
}
}

// Add the new report datasource to the report.
rv.LocalReport.DataSources.Add(rds);
rv.LocalReport.EnableHyperlinks = true;
rv.LocalReport.SetParameters(parameters);
rv.LocalReport.Refresh();
byte[] streamBytes = null;
string mimeType = "";
string encoding = "";
string filenameExtension = "";
string[] streamids = null;
Warning[] warnings = null;

I am running a month-end process and want to have it automatically create some of the reports that need to be created at that time. I am using rdlc reports. Is there a way to automatically create a PDF from a RDLC report in the background?
This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;
byte[] bytes = reportViewer.LocalReport.Render(
"PDF", null, out mimeType, out encoding, out filenameExtension,
out streamids, out warnings);
using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
fs.Write(bytes, 0, bytes.Length);
}
You can use following code which generate pdf file in background as like on button click and then would popup in brwoser with SaveAs and cancel option.
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;`enter code here`
string extension = string.Empty;
DataSet dsGrpSum, dsActPlan, dsProfitDetails,
dsProfitSum, dsSumHeader, dsDetailsHeader, dsBudCom = null;
enter code here
//This is optional if you have parameter then you can add parameters as much as you want
ReportParameter[] param = new ReportParameter[5];
param[0] = new ReportParameter("Report_Parameter_0", "1st Para", true);
param[1] = new ReportParameter("Report_Parameter_1", "2nd Para", true);
param[2] = new ReportParameter("Report_Parameter_2", "3rd Para", true);
param[3] = new ReportParameter("Report_Parameter_3", "4th Para", true);
param[4] = new ReportParameter("Report_Parameter_4", "5th Para");
DataSet dsData= "Fill this dataset with your data";
ReportDataSource rdsAct = new ReportDataSource("RptActDataSet_usp_GroupAccntDetails", dsActPlan.Tables[0]);
ReportViewer viewer = new ReportViewer();
viewer.LocalReport.Refresh();
viewer.LocalReport.ReportPath = "Reports/AcctPlan.rdlc"; //This is your rdlc name.
viewer.LocalReport.SetParameters(param);
viewer.LocalReport.DataSources.Add(rdsAct); // Add datasource here
byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
// byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
// Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
// System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file
Response.Flush(); // send it to the client to download
Response.End();
You don't need to have a reportViewer control anywhere - you can create the LocalReport on the fly:
var lr = new LocalReport
{
ReportPath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) ?? #"C:\", "Reports", "PathOfMyReport.rdlc"),
EnableExternalImages = true
};
lr.DataSources.Add(new ReportDataSource("NameOfMyDataSet", model));
string mimeType, encoding, extension;
Warning[] warnings;
string[] streams;
var renderedBytes = lr.Render
(
"PDF",
#"<DeviceInfo><OutputFormat>PDF</OutputFormat><HumanReadablePDF>False</HumanReadablePDF></DeviceInfo>",
out mimeType,
out encoding,
out extension,
out streams,
out warnings
);
var saveAs = string.Format("{0}.pdf", Path.Combine(tempPath, "myfilename"));
var idx = 0;
while (File.Exists(saveAs))
{
idx++;
saveAs = string.Format("{0}.{1}.pdf", Path.Combine(tempPath, "myfilename"), idx);
}
using (var stream = new FileStream(saveAs, FileMode.Create, FileAccess.Write))
{
stream.Write(renderedBytes, 0, renderedBytes.Length);
stream.Close();
}
lr.Dispose();
You can also add parameters: (lr.SetParameter()), handle subreports: (lr.SubreportProcessing+=YourHandler), or pretty much anything you can think of.
The below code work fine with me of sure thanks for the above comments. You can add report viewer and change the visible=false and use the below code on submit button:
protected void Button1_Click(object sender, EventArgs e)
{
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;
string extension = string.Empty;
string HIJRA_TODAY = "01/10/1435";
ReportParameter[] param = new ReportParameter[3];
param[0] = new ReportParameter("CUSTOMER_NUM", CUSTOMER_NUMTBX.Text);
param[1] = new ReportParameter("REF_CD", REF_CDTB.Text);
param[2] = new ReportParameter("HIJRA_TODAY", HIJRA_TODAY);
byte[] bytes = ReportViewer1.LocalReport.Render(
"PDF",
null,
out mimeType,
out encoding,
out extension,
out streamIds,
out warnings);
Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader(
"content-disposition",
"attachment; filename= filename" + "." + extension);
Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file
Response.Flush(); // send it to the client to download
Response.End();
}
private void PDFExport(LocalReport report)
{
string[] streamids;
string minetype;
string encod;
string fextension;
string deviceInfo =
"<DeviceInfo>" +
" <OutputFormat>EMF</OutputFormat>" +
" <PageWidth>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0.25in</MarginTop>" +
" <MarginLeft>0.25in</MarginLeft>" +
" <MarginRight>0.25in</MarginRight>" +
" <MarginBottom>0.25in</MarginBottom>" +
"</DeviceInfo>";
Warning[] warnings;
byte[] rpbybe = report.Render("PDF", deviceInfo, out minetype, out encod, out fextension, out streamids,
out warnings);
using(FileStream fs=new FileStream("E:\\newwwfg.pdf",FileMode.Create))
{
fs.Write(rpbybe , 0, rpbybe .Length);
}
}
You can instanciate LocalReport
FicheInscriptionBean fiche = new FicheInscriptionBean();
fiche.ToFicheInscriptionBean(inscription);List<FicheInscriptionBean> list = new List<FicheInscriptionBean>();
list.Add(fiche);
ReportDataSource rds = new ReportDataSource();
rds = new ReportDataSource("InscriptionDataSet", list);
// attachement du QrCode.
string stringToCode = numinscription + "," + inscription.Nom + "," + inscription.Prenom + "," + inscription.Cin;
Bitmap BitmapCaptcha = PostulerFiche.GenerateQrCode(fiche.NumInscription + ":" + fiche.Cin, Brushes.Black, Brushes.White, 200);
MemoryStream ms = new MemoryStream();
BitmapCaptcha.Save(ms, ImageFormat.Gif);
var base64Data = Convert.ToBase64String(ms.ToArray());
string QR_IMG = base64Data;
ReportParameter parameter = new ReportParameter("QR_IMG", QR_IMG, true);
LocalReport report = new LocalReport();
report.ReportPath = Page.Server.MapPath("~/rdlc/FicheInscription.rdlc");
report.DataSources.Clear();
report.SetParameters(new ReportParameter[] { parameter });
report.DataSources.Add(rds);
report.Refresh();
string FileName = "FichePreinscription_" + numinscription + ".pdf";
string extension;
string encoding;
string mimeType;
string[] streams;
Warning[] warnings;
Byte[] mybytes = report.Render("PDF", null,
out extension, out encoding,
out mimeType, out streams, out warnings);
using (FileStream fs = File.Create(Server.MapPath("~/rdlc/Reports/" + FileName)))
{
fs.Write(mybytes, 0, mybytes.Length);
}
Response.ClearHeaders();
Response.ClearContent();
Response.Buffer = true;
Response.Clear();
Response.Charset = "";
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + FileName + "\"");
Response.WriteFile(Server.MapPath("~/rdlc/Reports/" + FileName));
Response.Flush();
File.Delete(Server.MapPath("~/rdlc/Reports/" + FileName));
Response.Close();
Response.End();
