How to Print an ASP.NET Local Report RDLC without Preview or Printer Dialog
How to Print an ASP.NET Local Report RDLC without Preview or Printer Dialog
In this walkthrough, you'll learn how to print a Local Report (RDLC) from an ASP.NET website to the client printer without previewing the report through Visual Studio ReportViewer control. In fact, you'll be able to print the RDLC report without displaying any Printer Dialog at all! And one important thing... it works with any browser on Windows OS like IE (6 or later), Chrome, Firefox, Opera & Safari!

Print RDLC Local Report without Preview or Print Dialog
The sample report is a Local Report RDLC designed to print a product list of the classic and famous MS Northwind Traders database. In a simple ASP.NET webpage, we provide a preview of such report (just for you to know what to expect after printing) and all the needed code in C# and VB to print the report without previewing or displaying any printer dialog by using WebClientPrint for ASP.NET solution
You can print the RDLC local report to the Default client printer as well as to any other installed printer at the client machine.
Requirements
- WebClientPrint 2.0 for ASP.NET (or greater)
- ASP.NET 3.5 (or greater)
- Visual Studio 2010 / VWD 2010 (or greater)
- jQuery 1.4.1 (or greater)
- WebClientPrint Processor 2.0 for Windows & Adobe Reader need to be installed at the client machine
NOTE: In this guide we used VS 2010 and ASP.NET 3.5 but the same code & concept can be applied to VS 2005/2008 and ASP.NET 2.0 as well as VS 2012 and ASP.NET 4.x
Follow up these steps
- Download and install WebClientPrint for ASP.NET
- Open Visual Studio and create a new ASP.NET 3.5 Website naming it PrintRDLCReport
- Add a reference to Neodynamic.SDK.WebClientPrint.dll to your project
- Open your web.config file and add the following entries:
<system.web>
<httpHandlers>
<add verb="*" path="wcp.axd" type="Neodynamic.SDK.Web.WebClientPrint, Neodynamic.SDK.WebClientPrint"/>
</httpHandlers>
</system.web>
<system.webServer>
<handlers>
<add name="WCP" verb="*" path="wcp.axd" type="Neodynamic.SDK.Web.WebClientPrint, Neodynamic.SDK.WebClientPrint"/>
</handlers>
</system.webServer>
- Open the default.aspx page and paste the following markup. The task of this page is to try to detect the WCPP and ask the user to install it if it's missing.

<h3>#1 Install WebClientPrint Processor (WCPP)!</h3>
<p>
<strong>WCPP is a native Windows app (without any dependencies!)</strong> that handles all print jobs
generated by the <strong>WebClientPrint ASP.NET component</strong> at the server side. The WCPP
is in charge of the whole printing process and can be
installed on Windows 98, 2000, Me, XP, Vista, Windows 7 and Windows 8 (Desk-mode). It can print to Serial Port RS232 (e.g. COM1),
Parallel Port (e.g. LPT1), your Windows-Installed Printers (USB) and Network/IP Ethernet printers.
</p>
<p>
The <strong>WCPP</strong> utility <strong>is digitally-signed with a Windows Authenticode</strong> issued by <a href="http://www.digicert.com">DigiCert, Inc.</a>. <strong>Install WCPP only if the <u>Publisher is Neodynamic SRL</u></strong>, otherwise do not proceed. <br /><br />
<a href="http://www.neodynamic.com/downloads/wcpp20-installer.exe" target="_blank">Download and Install WCPP from Neodynamic website</a><br />

The Local Report RDLC we've created for this sample is a simple product list for MS Northwind Traders database and it has an XML data source. The report looks like the following figure.
http://www.neodynamic.com/articles/h...nd-traders.jpg
Sample RDLC report featuring Northwind Traders product list
- Download and copy both MyReport.rdlc & NorthwindProducts.xml files to your website root folder
- Finally, add a new ASPX page and name it PrintRDLC.aspx (be sure to UNSELECT the "Place code in separate file" checkbox)
This page allows your user to print the RDLC report to local printers. It basically converts the report to PDF format and then passes it to the WCPP utility to print it to the specified printer. The user is required to have Adobe Reader installed to get this code working.
Please paste the following markup and code depending on your preferred language i.e. C# or VB on your PrintRDLC.aspx file.

- That's it! Run your website and test it. Click on Print Report to print the RDLC report without preview. You can print it to the Default client printer or you can get a list of the installed printers available at the client machine and select one for printing the report.
