Type: Feature Request
Share PDF for print, email, text, etc

Most PDF Viewers come with the ability to print, email, text etc the PDF that is loaded.  For example, in the default iOS PDF viewer there is a "share" icon.  When the "share" icon is tapped, multiple options and apps come up that allow users to "print", "message/text", "email" the PDF.  It would be a great feature to have in the Xamarin UI PDF Viewer.  It could just be part of the PDFViewer Toolbar options.

Hi Sadanan,

Yes, you can add a toolbar item of type PdfViewerToolbarItemBase to the PdfViewerToolbar and set its Text/FontFamily and Command properties. Text / FontFamily could be used to apply an icon and Command could be bound to any Xamarin.Forms.Command.

Please check the following sample implementation:

        <RowDefinition Height="Auto"/>
        <RowDefinition />
    <telerikPdfViewer:RadPdfViewerToolbar PdfViewer="{Binding Source={x:Reference pdfViewer}}">
        <telerikPdfViewer:ZoomInToolbarItem />
        <telerikPdfViewer:ZoomOutToolbarItem />
        <telerikPdfViewer:PdfViewerToolbarItemBase Text="Save" Command="{Binding SavePdfDocumentCommand}" />
    <telerikPdfViewer:RadPdfViewer x:Name="pdfViewer" Grid.Row="1"/>

and the code-behind:

public partial class MainPage : ContentPage
    public ICommand SavePdfDocumentCommand { get; set; }
    public MainPage()

        this.BindingContext = this;

        Func<CancellationToken, Task<Stream>> streamFunc = ct => Task.Run(() =>
            Assembly assembly = typeof(MainPage).Assembly;
            string fileName = assembly.GetManifestResourceNames().FirstOrDefault(n => n.Contains("pdfviewer-overview.pdf"));
            Stream stream = assembly.GetManifestResourceStream(fileName);
            return stream;
        this.pdfViewer.Source = streamFunc;

        this.SavePdfDocumentCommand = new Command(this.SavePdfDocumentCommandExecute);

    protected void SavePdfDocumentCommandExecute()
      //custom implementation for saving the document

Let me know if any additional questions on this pop up.

Thanks for the clarification. If so, is there a possibility to create custom command in pdf toolbar space, something like SAVE PDF button/icon inside which we can write our custom implementation to save or share pdf. This will enhance UX instead of creating Save button somewhere else on the page.

Hi Sadanan,

Thank you for your comment. 

Currently this functionality is not in our immediate plans for the upcoming release.

As for the Save PDF option - this could be achieved as of now with a custom implementation as you have the pdf as a stream/file (depending on how it is loaded). Additionally, this functionality deals with the device permissions and we would like to leave managing the permissions requested by the app to the app development team.

Thank you for the understanding.

Please consider this enhancement. Or at the very least Save PDF option should be provided so that the user can save the pdf in local device and then do share, print, email etc.
