How can I feed the password in the viewmodel to display a password protected pdf in SfPdfViewer

[Madhu Ganesh]

I have a password protected pdf that I would liked to display in my SfPdfViewer without asking the user to enter the password. I will be feeding the password through the viewmodel. I tried to use some code under "Set user password using event when accessing the attachment" on this page: https://help.syncfusion.com/file-formats/pdf/working-with-security?cs-save-lang=1&cs-lang=xamarin and came up with the following.

 I need a way to feed document22 into the pdfviewer because the code below still asks for password once the pdf loads. 

//========================

     

{

                Stream docStream = typeof(App).GetTypeInfo().Assembly.GetManifestResourceStream("Sample.Assets.Input.pdf");

                

                //Creates an empty PDF loaded document instance 

                PdfLoadedDocument document22 = new PdfLoadedDocument(docStream, "password");

                MemoryStream stream1 = new MemoryStream();

                document22.Save(stream1);

                PdfDocumentStream = stream1;

}

public Stream PdfDocumentStream

        {

            get { return m_pdfDocumentStream; }

            set

            {

                m_pdfDocumentStream = value;

                OnPropertyChanged();

            }

        }

//=======================================

In the view I have "InputFileStream="{Binding PdfDocumentStream, Mode=TwoWay}" for the sfPdfViewer

Thanks,

Madhu

Hi Madhu, 

Greetings from Syncfusion support, 

Currently, we have the support to load encrypted PDF document only using the following API, 

pdfViewerControl.LoadDocument(stream,”password”); 

We do not have the support to load the encrypted document by passing the pdfStream to the InputStream of SfPdfViewer control. Currently, we are analyzing the feasibility for the support and we will update the further details on July 1^st 2020.

Ashok Kumar Viswanathan.

Hi Madhu, 

   

At present, we do not have support to load password protected PDF using data binding in Xamarin platform. We do not have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.      

       

Based on our present commitments and the above parameters, this feature is expected to be implemented in our 2021 Volume 3 Main Release. We will let you know when this feature is implemented.     

    

Disclaimer: The date for the feature implementation is tentative and not a commitment on our parts.      

      

You can now track the status of this feature request here,
