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();
}

using(FileStream fs=new FileStream("E:\\newwwfg.pdf",FileMode.Create))
{

}
You can instanciate LocalReport
FicheInscriptionBean fiche = new FicheInscriptionBean();
fiche.ToFicheInscriptionBean(inscription);List<FicheInscriptionBean> list = new List<FicheInscriptionBean>();

var base64Data = Convert.ToBase64String(ms.ToArray());
string QR_IMG = base64Data;
ReportParameter parameter = new ReportParameter("QR_IMG", QR_IMG, true);

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;
}
}

Use WORDOPENXML instead of WORD when you render the report. Also, this was discussed here:

I am using Reportviewer in asp.net mvc and rendering it as a pdf format after converting it into byte.
The code is given below:

if (System.IO.File.Exists(path))

renderedBytes = lr.Render(
reportType,
deviceInfo,
out mimeType,
out encoding,
out fileNameExtension,
out streams,
out warnings);
FileContentResult fileResult = File(renderedBytes, mimeType);
return fileResult;
}
I want to save this file to my server location. For example: /Content/PDF/Result1.pdf
I want to make a copy of rendered bytes into file so that I can see preview of it later also.
How can I achieve it? I am not using html FileUpload control.
Please help me.
Thanks.
You can save it using FileStream in server-side.
using (FileStream fileStream = System.IO.File.Create(filePath, renderedBytes.Length)){
fileStream.Write(renderedBytes, 0, renderedBytes.Length);
}
I've added the code to save file in specified file path(/Content/PDF/Result1.pdf) at the end of the method before setting FileContentResult
public ActionResult PrintPO(string type)
{
LocalReport lr = new LocalReport();
string path = Url.Content(Server.MapPath("~/Report/RepPurchaseOrder.rdlc"));
if (System.IO.File.Exists(path))
{
lr.ReportPath = path;
}
else
{
return Content("Report File Not Found!");
}
ReportDataSource rd = new ReportDataSource("Data", list));
lr.DataSources.Add(rd);

string deviceInfo =

" <OutputFormat>" + id + "</OutputFormat>" +
" <PageWidth>10in</PageWidth>" +

" <MarginTop>0.5in</MarginTop>" +
" <MarginLeft>1in</MarginLeft>" +
" <MarginRight>1in</MarginRight>" +
" <MarginBottom>0.5in</MarginBottom>" +
"</DeviceInfo>";
Warning[] warnings;
string[] streams;
byte[] renderedBytes;
renderedBytes = lr.Render(
reportType,
deviceInfo,
out mimeType,
out encoding,
out fileNameExtension,
out streams,
out warnings);
//Saving renderedBytes to File ~/Content/PDF/Result1.pdf
var filesDir = Server.MapPath(#"~/Content/PDF");
if (!Directory.Exists(filesDir)) {
Directory.CreateDirectory(filesDir);
}
var filePath = Path.Combine(filesDir, "Result1.pdf");
using (FileStream fileStream = System.IO.File.Create(filePath, renderedBytes.Length)) {
fileStream.Write(renderedBytes, 0, renderedBytes.Length);
}
FileContentResult fileResult = File(renderedBytes, mimeType);
return fileResult;
}
