Here i am explaining a small method which i am adopted for automatically printing an rdlc file in my Asp.Net MVC3 application.
In my Asp.Net MVC 3 application I had suffered with the report section. We are using the client definition (rdlc) of Reporting Service for report creation. But the things were stuck on one scenario where our client needs to automatically print the reports by specifying a particular printer name which is presented.
After a lot of googling I realized that it is a hard scenario. Finally we decided to achieve it with acrobat reader and java script to pdf. Requirement is that you must install the acrobat reader plugin in your browser.
The requirement is that there is a printer setting where we are setting a particular printer for a particular report by providing the IP address of the system. According to these settings a particular report must print through a printer which is provided in the settings table.
Using the code
First we designed the report using rdlc. The next step is converting the rdlc to pdf from the action method in the controller. Also we need to inject the javscript for automatically printing the report in acrobat viewer. For that with the help of iTextSharp dll we converted the rdlc file into pdf at the same time we injected some javscript for automatic printing to the pdf.
You need to include the following namespaces which is in iTextSharp DLL
The action method is as follows
public void RecieptPrint(long inv_ReceiptID)
LocalReport localReport = new LocalReport();
localReport.ReportPath = @”Reprt1.rdlc”;
DataTable dt = DataSelect();
The following code is for dynamically setting the data source to rdlc. I already wrote about this here
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Value = dt;
reportDataSource.Name = “DataSet1”;
string reportType = “PDF”;
string mimeType; string encoding;
string fileNameExtension = “pdf”;
//The DeviceInfo settings should be changed based on the reportType
string deviceInfo =@”<DeviceInfo>
Now we are going to converting the rdlc to byte array using the above device info for pdf . To know more about it click here
deviceInfo,out mimeType, out encoding, out fileNameExtension,out streams,out warnings);
var doc = new Document();
var reader = new PdfReader(renderedBytes);
using (FileStream fs = new FileStream(Server.MapPath(“~/Summary”+ Convert.ToString(Session[“CurrentUserName“]) + “.pdf“), FileMode.Create))
PdfStamper stamper = new PdfStamper(reader, fs);
string Printer = PrinterName(Convert.ToInt32(Session[“localOutletID“]));
// This is the script for automatically printing the pdf in acrobat viewer
In view using an iframe we can render this pdf and it will be printed automatically. Requirement is that you must install the acrobat reader plugin in your browser.
Points of Interest
If we saved that pdf instead of printing while opening it will be printed automaticlay.
