This tutorial illustrates how to embed a PDF Viewer in a Windows Forms application, to open, preview, navigate and print PDF documents without the need to install third-party software on the machine.

The tutorial consists of the following sections.

• Create an Application and Add a PDF Viewer
• Create and Customize a PDF Viewer Toolbar
• Load and Preview a PDF File

Create an Application and Add a PDF Viewer

1. Run Microsoft® Visual Studio® 2010, 2012 or 2013.

2. Start a new project (by pressing CTRL+SHIFT+N), and create a new Windows Forms Application.

   

3. Open the Visual Studio designer and press CTRL+ALT+X to run the Toolbox. Expand the DX.14.1: Common Controls category, and drop the PdfViewer control onto the main form of the application.

   

Create and Customize a PDF Viewer Toolbar

To add a toolbar to the PDF Viewer, click the control's smart tag, and in the invoked actions list, select one of the following.

• Create Ribbon

  This creates a ribbon illustrated in the following image.

  

  You can fully customize the ribbon afterwards, as well as select a different look and feel for it, via the smart tag of the toolbar.

  

• Create Bars

  Instead of creating a ribbon, you can implement a bar interface. You can upgrade it to the ribbon interface at any time (e.g., when converting the entire application).

  

Load and Preview a PDF File

To load a document into the PDF Viewer, click the control's smart tag and select Load PDF File... in the actions list that is invoked.

The following code opens a PDF file at runtime.

The complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E4696. Depending on the target platform type (ASP.NET, WinForms, etc), you can either run this example online or download an auto-executable sample.

The following example illustrates how to load an existing PDF file into the PdfViewer control. To do this, it's necessary to drop thePdfViewer control onto the form, create a Ribbon via the PdfViewer's smart tag and call the PdfViewer.LoadDocument method.

C#:Form1.cs

VB:Form1.vb

using System;using System.Windows.Forms;namespace PdfViewerSample {    public partial class Form1 : Form {        public Form1() {            InitializeComponent();        }        private void Form1_Load(object sender, EventArgs e) {            this.pdfViewer1.LoadDocument(@"..\..\Report.pdf");        }    }}

Run the application and explore the PDF Viewer functionality.
