I am trying to implement a behavior somehow like https://docs.telerik.com/devtools/winforms/controls/pdfviewer/features/digital-signature on this link but on asp.net ajax. I need to prompt the user to sign the pdf file and then save it to my database. My problem is how to add the "PdfViewerElement.AllowSignatureDialog" on asp.net ? It seems like it's working only in Winforms. Is there any similar control to have the same behavior and ask the user to upload a pfx file and a password ?
Thank you !
