How to download a PDF using AJAX Call

Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can download PDF documents using AJAX Call.

A file cannot be downloaded with AJAX directly. You can request a file using AJAX, but AJAX response will contain the actual file stream. Due to JavaScript limitations, you cannot save the stream on the user’s machine with a file download dialog. As a work around, you can check the status of the PDF generation and then export the document after saving in the disk using AJAX call.

Steps to download PDF using AJAX call programmatically:

  1. Create a new ASP.NET MVC application project.
