I just want to view a pdf in a frame. On webforms I used an HtmlGenericControl.

If I used the PDF Viewer I believe that I need to use the api for this? If so, can I add the API to my existing solution?

Thank you.

Hi Stephen,

Thank you for contacting Syncfusion support.

Our PDF Viewer control is both server and the client side oriented. PDF viewer control processes the PDF document in the server side(developed with .NET environment) and send the processed PDF data to the client using the Web service to render the PDF document and for further operations in PDF viewer.

Our PDF Viewer Server Side Blazor application has the built-in server side codes, so it does not required to configured separately in the project. Please refer to the below UG link to create PDF Viewer Server side blazor project,

Server Side Blazor: https://blazor.syncfusion.com/documentation/pdfviewer/getting-started/server-side-application/

PDF Viewer Client side Blazor application requires the Web service project and it is referred using the serviceUrl project. Please refer to the below UG link to create PDF Viewer Client side blazor project,

Client Side Blazor: https://blazor.syncfusion.com/documentation/pdfviewer/getting-started/client-side-application/

We can also create our own web Service Project using this link, https://www.syncfusion.com/kb/11063/how-to-create-the-pdf-viewer-web-service-application-in-net-core-3-0-and-above-version

Please try it and revert us with more details if you need any further assistance.

Regards,

Thank you. The youtube video helped me accomplish this. Do you have an example for AWS S3 rendering of pdf. I have 2 methods,1) a stream and 2) a presigned URL.

I have the stream coming down as a filestream and I quess I need to convert to bytes and then to base64 but I get an error that cannot convert filesstream to string.

var streamPath = AwsService.ReadFileAsync("123.pdf", "ABC");

byte[] bytes = System.IO.File.ReadAllBytes(streamPath);

DocumentPath = "data:application/pdf;base64," + Convert.ToBase64String(bytes);

Regarding presigned url, how do I assign a url?

public string DocumentPath { get; set; } = @"http:\\abc.com\test.pdf";
