XFA support in XDP-based adaptive forms

Introduction

Adaptive forms provides support for various XFA events, properties, scripts, and validations defined in an XDP file, including:
  • Execution of scripts defined on events in the XDP file.
  • Capturing default values and behavioral properties for fields in the XDP file.
  • Execution of validation scripts defined in the XDP file.
When an adaptive form is created based on an XDP file, the properties, events, and validations are auto-populated in the form authoring UI. However, form authors can override some of these elements to create an alternate experience.
This article lists supported XFA events, properties, and validations honored in adaptive forms and explains how to override them in adaptive forms.
