Getting Started
This article will guide you through the steps needed to add a basic RadPdfViewer control in your application.
- Setting up the app
- Adding the required Telerik references
- Adding RadPdfViewer control
- Visualize a Pdf Document
1. Setting up the app
Take a look at these articles and follow the instructions to setup your app:
2. Adding the required Telerik references
You have two options:
- Add the Telerik UI for Xamarin Nuget package following the instructions in Telerik NuGet package server topic.
If you don't want to add the all Telerik.UI.for.Xamarin nuget package, you have the option to add a separate nuget package. For RadPdfViewer control you have to install the Telerik.UI.for.Xamarin.PdfViewer nuget package. This nuget will automatically refer the Telerik.UI.for.Xamarin.Common, Telerik.UI.for.Xamarin.Primitives, Telerik.UI.for.Xamarin.SkiaSharp, SkiaSharp and SkiaSharp.Views.Forms nuget packages.
- Add the references to Telerik assemblies manually, check the list below with the required assemblies for RadPdfViewer component:
| Platform | Assemblies |
|---|---|
| Portable | Telerik.Documents.Core.dll Telerik.Documents.Fixed.dll Telerik.XamarinForms.PdfViewer.dll Telerik.XamarinForms.Common.dll Telerik.XamarinForms.Primitives.dll Telerik.XamarinForms.SkiaSharp.dll |
| Android | Telerik.Documents.Core.dll Telerik.Documents.Fixed.dll Telerik.Xamarin.Android.Primitives.dll Telerik.Xamarin.Android.Common.dll Telerik.XamarinForms.PdfViewer.dll Telerik.XamarinForms.Common.dll Telerik.XamarinForms.Primitives.dll Telerik.XamarinForms.SkiaSharp.dll |
| iOS | Telerik.Documents.Core.dll Telerik.Documents.Fixed.dll Telerik.Xamarin.iOS.dll Telerik.XamarinForms.PdfViewer.dll Telerik.XamarinForms.Common.dll Telerik.XamarinForms.Primitives.dll Telerik.XamarinForms.SkiaSharp.dll |
| UWP | Telerik.Core.dll Telerik.Documents.Core.dll Telerik.Documents.Fixed.dll Telerik.UI.Xaml.Primitives.UWP.dll Telerik.XamarinForms.PdfViewer.dll Telerik.XamarinForms.Common.dll Telerik.XamarinForms.Primitives Telerik.XamarinForms.SkiaSharp.dll |
Please keep in mind that Telerik.Documents.Core.dll and Telerik.Documents.Fixed.dll assemblies are located in the Portable folder, still, you need to add a reference to them in each of the platform projects.
3. Adding RadPdfViewer control
You could use one of the following approaches:
Drag the control from the Toolbox.
Take a look at the following topics on how to use the toolbox:
Create the control definition in XAML.
<telerikPdfViewer:RadPdfViewer x:Name="pdfViewer" />
In addition to this, you need to add the following namespace:
xmlns:telerikPdfViewer="clr-namespace:Telerik.XamarinForms.PdfViewer;assembly=Telerik.XamarinForms.PdfViewer"
4. Visualize a Pdf Document
To visualize the pdf document you will need to set the Source property of the control.
- Source (DocumentSource): Defines the source of the document.
The example below shows a pdf document visualized as an EmbeddedResource. This is one of the options for loading a pdf inside PdfViewer control, you could check the others in the Key Features topic.
Func<CancellationToken, Task<Stream>> streamFunc = ct => Task.Run(() =>
{
Assembly assembly = typeof(PdfViewerGettingStartedXaml).Assembly;
string fileName = assembly.GetManifestResourceNames().FirstOrDefault(n => n.Contains("pdfviewer-overview.pdf"));
Stream stream = assembly.GetManifestResourceStream(fileName);
return stream;
});
this.pdfViewer.Source = streamFunc;
This is the result:
