Displaying a PDF file within a WPF application

April 6, 2009 — Christopher Hujanen

I had a need to view PDF files directly within a WPF application and Stackoverflow and Google did not provide much assistance, so I set out on my own to see what I could create.  It turns out, it is not that difficult.  The trick is to use the WinForms support in WPF ala the WindowsFormHost control.  The application is so simple, I built it start to finish in under 5 minutes and captured it in a screencast for you to check out.

The code is very simple, here’s the whopping 2 lines that I changed from the default usercontrol template:

view source

print?

1	public partial class UserControl1 : UserControl

2

{

3	public UserControl1(string filename)

4

{

5	InitializeComponent();

6

7	this.axAcroPDF1.LoadFile(filename);

8

}

9

}

The only other code change I made is in creating an instance of the user control in the code behind of my WPF window:

view source

print?

1	public Window1()

2

{

3	InitializeComponent();

4

5	// TODO: Make sure you point to a PDF on your system:

6	var uc = new UserControl1(@"C:\FoundationsOfProgramming.pdf");

7	this.windowsFormsHost1.Child = uc;

8

}

The code is free for you to use: WpfPDFViewer.zip. Note it is a Visual Studio 2008 solution, and you must have Adobe Acrobat installed on your system of course.
