Use ShowToolbar and ShowEditToolbar properties to display or hide PDF viewer toolbars.

Add a PDF Viewer to the Page

Download and install the DevExpress.Maui.Pdf package from the DevExpress NuGet Gallery to obtain the PdfViewer component. For more information on how to build your first .NET MAUI app, refer to the following help topic: Get Started.

The following code snippet adds a PDF viewer to a page:

• XAML

DevExpress PDF Document API

The PDF Document API library allows you to use the following features in your PDF Viewer-powered app:

• Export and import interactive form data in code
• Password-protect a document and specify a signature
• Edit form field properties
• Flatten annotations

The following example uses Office File API to sign PDF files in a .NET MAUI App:

Note

The digital signature API ships with the Office File API library. You need an active license for the DevExpress Office File API Subscription to use this feature in production code. For pricing information, refer to the following page: DevExpress Subscription Plans.

To sign documents in the PDF Viewer UI, you need a license that includes only DevExpress .NET MAUI controls. For more information about built-in digital signature functionality, refer to: Sign Documents in DevExpress PDF Viewer.

Area of Application and Limitations

Our mobile .NET MAUI PDF Viewer is designed to view simple documents. Before integrating a PDF Viewer into your application, check if the control meets your requirements and consider the following points:

• PDF Viewer ships with basic document editing features and does not include the full capabilities of native PDF editors (for example, Adobe Acrobat).
• PDF Viewer is not optimized for large size documents with multiple pages, complex structures, and large/high-resolution images. Complex documents are rendered slower due to the internal architecture (beyond hardware and OS differences for mobile and desktop devices).
• Uncommon PDF elements and fonts may appear unconventionally or may not display in the same way as in specialized or native PDF viewers.

We recommend testing your application under conditions similar to the production environment, using real PDF documents, target mobile devices, and operating systems.
