Not able to load XPS document on on DocumentViewer

You can load that XPS file using the WPF DocumentViewer provided through the LEADTOOLS SDK. Here is some sample code that highlights the tutorial:

private ObjectCache cache; 
private DocumentViewer docViewer; 

void InitDocumentViewer() 
{ 
    var createOptions = new DocumentViewerCreateOptions 
    { 
        ViewContainer = _centerGrid, 
        ThumbnailsContainer = _thumbnailsTabPageGrid, 
        UseAnnotations = false 
    }; 
    docViewer = DocumentViewerFactory.CreateDocumentViewer(createOptions); 
    docViewer.View.ImageViewer.Zoom(ControlSizeMode.FitAlways, 1, docViewer.View.ImageViewer.DefaultZoomOrigin); 
    cache = new FileCache 
    { 
        CacheDirectory = Path.GetFullPath(@".\CacheDir"), 
    }; 
}

Hi David ,

1. Add a reference to the WindowsBase and PresentationCore assemblies in your project. These assemblies are required to work with XPS documents.

2. In your XAML file, add the DocumentViewer control to your UI layout.

 

In your C# code, you need to load and display the XPS document using the DocumentViewer

using System.Windows;
using System.Windows.Controls;
using System.Windows.Xps.Packaging;

namespace YourNamespace
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            LoadXpsDocument();
        }

        private void LoadXpsDocument()
        {
            // Replace "path_to_your_xps_file.xps" with the actual path to your XPS document.
            string xpsFilePath = "path_to_your_xps_file.xps";

            try
            {
                XpsDocument xpsDocument = new XpsDocument(xpsFilePath, System.IO.FileAccess.Read);
                documentViewer.Document = xpsDocument.GetFixedDocumentSequence();
            }
            catch (System.IO.FileNotFoundException)
            {
                MessageBox.Show("The specified XPS document file was not found.");
            }
            catch (System.IO.FileFormatException)
            {
                MessageBox.Show("The specified file is not a valid XPS document.");
            }
        }
    }
}

 

In the LoadXpsDocument() method, you create an instance of the XpsDocument class by providing the path to your XPS document file. Then, you set the Document property of the DocumentViewer control to the FixedDocumentSequence obtained from the XpsDocument.

Make sure to replace "path_to_your_xps_file.xps" with the actual path to your XPS document.

That's it! When you run your application, it should load and display the XPS document in the DocumentViewer control.

Consider using a FixedDocument control: Create a FixedDocument object and add the XPS document to it, then set it as content into a DocumentPanel control or other container.

XpsDocument xpsDocument = new XpsDocument("..\\..\\Sample.xps", FileAccess.Read);
FixedDocumentSequence fixedDocumentSequence = xpsDocument.GetFixedDocumentSequence();
FixedDocument fixedDocument = fixedDocumentSequence.References[0].GetDocument(false);
DocumentPanel documentPanel = new DocumentPanel();
documentPanel.Children.Add(fixedDocument.DocumentPaginator.GetPage(0).Visual);

Hello Saumya,

You can use the "FlowDocumentReader" control to display an XPS document in WPF.

You can get more details here: https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.flowdocumentreader?view=windowsdesktop-7.0
