How to Print an ASP.NET Local Report RDLC without Preview or Printer Dialog

Product WebClientPrint for ASP.NET Published 03/31/2013 Updated 12/26/2017 Author Neodynamic

Overview

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, Edge, Chrome, Firefox, Opera & Safari as well as on Linux & Mac OS clients!

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

Development/Server-side

WebClientPrint 6.0 for ASP.NET (or greater)
ASP.NET 4.6.1+ or ASP.NET Core 2.0+
Visual Studio 2015+
jQuery 1.4.1+

Client-side

WebClientPrint Processor 6.0 for Windows, Linux, Raspberry Pi & Mac

Follow up these steps

Open Visual Studio and create a new ASP.NET Website naming it PrintRDLCReport
Add a NuGet reference to Neodynamic.SDK.WebClientPrint package to your project

Now follow up the instructions for each WebForms/CS or WebForms/VB:

Adding sample RDLC local report

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.

Creating/Editing WebForm Pages

Be sure ALL *.aspx link to jQuery 1.4.1+ file!

The default page is for detecting whether the client machine has the WebClientPrint Processor (WCPP) Utility installed. Edit the Default.aspx file and copy/paste the following code inside the BODY:

    <h3>#1 Install WebClientPrint Processor (WCPP)!</h3>
    <p>
        <strong>WCPP is a native app (without any dependencies!)</strong> that handles all print jobs
        generated by the <strong>WebClientPrint for ASP.NET component</strong> at the server side. The WCPP
        is in charge of the whole printing process and can be
        installed on <strong>Windows, Linux, Mac & Raspberry Pi!</strong>
