How to Validate form fields in PDF Viewer?
Essential JS 2 PDF Viewer
The PDF Viewer in ASP.NET MVC (Essential JS 2) is a modern enterprise UI toolkit that has been built from the ground up to be lightweight, responsive, modular, and touch-friendly. It also available in other frameworks, such as JavaScript Angular and React.
Refer to the following UG link for getting started with the PDF Viewer.

The form fields in the PDF Viewer will be validated when the enableFormFieldsValidation is set to true and hook the validateFormFields.
The validateFormFields will be triggered when the PDF document is downloaded or printed with the non-filled form fields.
The non-filled fields will be obtained in the ‘nonFillableFields’ property of the event arguments of validateFormFields.
Code Sample
@Html.EJS().PdfViewer("pdfviewer").ServiceUrl(VirtualPathUtility.ToAbsolute("~/PdfViewer/")).ValidateFormFields("validateFormFields").EnableFormFieldsValidation(true).DocumentPath("HTTP Succinctly.pdf").Render()
function validateFormFields(args) {
var nonfilledFormFields = args.nonFillableFields
}
