Add a PDF Viewer to the Page

Before you proceed, read the following topic: Get Started with DevExpress Controls for .NET Multi-platform App UI (.NET MAUI).

The following example adds a PDF viewer to a page:

XAML

<ContentPage ...
             xmlns:dxpdf="clr-namespace:DevExpress.Maui.Pdf;assembly=DevExpress.Maui.Pdf">
        <dxpdf:PdfViewer x:Name="pdfViewer" />
</ContentPage>

The PdfViewer requires that you call the UseSkiaSharp() method to use the Skia graphics engine to render PDF document pages:

MauiProgram.cs

using DevExpress.Maui;
using SkiaSharp.Views.Maui.Controls.Hosting;

namespace DXMauiPdfViewer {
    public static class MauiProgram {
        public static MauiApp CreateMauiApp() {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .UseDevExpress(useLocalization: true)
                .UseSkiaSharp()
                .ConfigureFonts(fonts => {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("univia-pro-regular.ttf", "Univia-Pro");
                    fonts.AddFont("roboto-bold.ttf", "Roboto-Bold");
                    fonts.AddFont("roboto-regular.ttf", "Roboto");
                });
            return builder.Build();
        }
    }
}
