Platform: ASP.NET Web Forms |
Control: PdfViewer |
Published Date: April 13, 2018 |

Currently, PDF viewer does not support Digital Signature, but you can integrate Digital Signature in the PDF viewer control.

The following code illustrates how to upload the PdfCertificate(.pfx) file on the ‘PageClick’ event of the PDF viewer and send the uploaded file to the Server side using Ajax request.

Find the sample for integrating the Digital Signature to the PDF viewer control from http://www.syncfusion.com/downloads/support/directtrac/general/ze/Sample1094583529

The previous sample uploads the Digital Signature(PdfCertificate(.pfx)) on the ‘PageClick’ event of the PDF Viewer and sends the uploaded file to the server side using the Ajax request. In the server side the digital signature is added to the PDF document as a signature field using the Syncfusion Pdf library, then the PDF document along with the signature is saved locally in the server side.
