We have a PDF on ASP.NET web page with some content related to business contract. User has to accept the contract by signing (clicking the buttons) on that PDF. It may be possible user have to put more than one signature on that PDF. The numbers of signatures required on PDF are coming from the database. After signing on PDF (putting the signatures at all required places) we have to update the status in database that PDF has been signed. We need not require saving the PDF
Implementation approach, which we are following:
2. We have created a web page having an Iframe and a submit button. In Iframe we are displaying the PDF document.
Till here every thing is working fine.
The submit button has to send the notification to web server that the PDF document has been signed.
Problem, that arises:
How we will check that all the signatures have been put or not inside PDF on clicking the submit button on the web page?
Does anyone have better opinions for the implementation of this functionality, please suggest.
