I want to change report title dynamically using local report

Hi,

I export a LocalReport to a PDF file, I use the LocalReport.Render(...) method, but the title of PDF is the

file name of the LocalReport.

If the LocalReport file is "NBISIAReport.rdlc", the title of PDF will be "NBISIAReport".

I want to define the title dynamically. Thanks an advance...

Here is My Code

[HttpPost]
public ActionResult GenerateMultipleNBISIAReport(List structures)
{
try
{
//var dirName = User.Identity.Name.Replace(" ", "");
DateTime currDate = DateTime.Now;
string dirName = "NBI-SIA_Reports" + "_" + currDate.ToString("MM") + "_" + currDate.ToString("dd") + "_" + currDate.ToString("yy") + "_" + currDate.ToString("HH") + "_" + currDate.ToString("mm");
var reportFolderPath = Request.MapPath(Request.ApplicationPath) + "Downloads/" + dirName;
const string fileExtension = "PDF";
var zipFolderPath = reportFolderPath + "/" + dirName + ".zip";
var exists = Directory.Exists(reportFolderPath);
if (!exists)
{
Directory.CreateDirectory(reportFolderPath);
}
else
{
Directory.Delete(reportFolderPath, true);
Directory.CreateDirectory(reportFolderPath);
}
foreach (var structure in structures)
{
if (structure.Id == null) continue;
string reportName;
string reportPath;
string reportTitle;
switch (structure.StrKindCode)
{
case "1":
reportPath = Request.MapPath(Request.ApplicationPath) + @"Reports\NBISIAReport.rdlc";
reportName = structure.StrNumber + "-Bridge.pdf";
break;
case "2":
reportPath = Request.MapPath(Request.ApplicationPath) + @"Reports\NBISIAReport.rdlc";
reportName = structure.StrNumber + "-Culvert.pdf";
break;
case "3":
reportPath = Request.MapPath(Request.ApplicationPath) + @"Reports\NBISIAReport.rdlc";
reportName = structure.StrNumber + "-Tunnel.pdf";
break;
case "4":
reportPath = Request.MapPath(Request.ApplicationPath) + @"Reports\NBISIAReport.rdlc";
reportName = structure.StrNumber + "-Trail.pdf";
break;
default:
reportPath = Request.MapPath(Request.ApplicationPath) + @"Reports\NBISIAReport.rdlc";
reportName = structure.StrNumber + "-Other.pdf";
break;
}
var localReport = new LocalReport
{
ReportPath = reportPath
};
var obj = new InspectionReportData();
var ds = obj.GetNBISIAReportData(Convert.ToInt32(structure.Id), AgencyCode);
localReport.DataSources.Add(new ReportDataSource("NBISIAReportDataSet", ds.Tables[0]));
localReport.DataSources.Add(new ReportDataSource("NBISIABIPReportDataSet", ds.Tables[1]));
localReport.EnableExternalImages = true;
localReport.DisplayName='Bridge NBI SIA Report';
var renderByte = localReport.Render(fileExtension, "");
using (var fileStream = new FileStream(reportFolderPath + "/" + reportName, FileMode.Create))
{
fileStream.Write(renderByte, 0, renderByte.Length);
}
}
using (var zip = new ZipFile())
{
zip.AddDirectory(reportFolderPath);
zip.Save(zipFolderPath);
}
dirName = string.Empty;
return Json(new { success = true, filePath = zipFolderPath }, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
return Json(new { success = false, message = ex.Message }, JsonRequestBehavior.AllowGet);
}
}

Well, I couldn't take the pain to look at the title, as it is only visible in detailed software like Adobe Reader and not in generally its properties (file->right click-> properties)

Anyway, I didn't try this and found some answers from the below link, you can try this

If the above link doesn't work then you might have to choose third party libraries to change the properties of the PDF individually

Ok. I have NBISIAReport.rdlc file so it will take title as without extension. So it will show NBISIAReport in report title properties.

Can you share some screenshot of what you said

i want title like 0630-001-Bridge but now showing that title in pdf file properties like NBISIAReport

As the syntax is working in code behind and doesn't showing any print dialog box for filename then where did you find the title?

FileStream creates file which is supplied in the parameter, Isn't file created by the name of 0630-001-Bridge.pdf ?

LocalReport.Render(..) returns only the bytes and not the file name, filename is handled by the filestream. I suggest you to re-check the folder path, it might be some ambigious understanding in D:\ParthInfotechProjects\ams\SDMS_MVC_WEB\Downloads/Inspection_Reports_03_09_20_05_14

Try changing the folderpath to other location and see what's happening, if none works then clean and rebuild your project sometimes this also works.

Your code seems good, isn't it generating filename with pdf extension?

Try passing full param to the render of the local report

Replace the line

var renderByte = localReport.Render(fileExtension, "");

with
public byte[] GetBytes(LocalReport localReport)

       {

           Warning[] warnings;

           string[] streamids;

           string mimeType;

           string encoding;

           string filenameExtension;



           byte[] bytes = localReport.Render(

               "PDF", null, out mimeType, out encoding, out filenameExtension,

               out streamids, out warnings);



           return bytes;

       }
var renderByte = GetBytes(localReport);
then write the renderBytes to filestream and dubug your project and check the path and filename passed in the FlieStream or clean and rebuild your project.

Do let me know, if it solves your problem.
