Simplifying Field Validation with PXUIVerify Attribute

Overview

Field validation is a common task in Acumatica development. Traditionally, developers use event handlers like FieldVerifying and RowPersisting, but the PXUIVerify attribute provides a cleaner, declarative approach that significantly reduces code complexity.

Traditional Approach: Event Handlers

To validate that a Margin field is between 0 and 100, you would typically write event handler code:

This requires 30+ lines of code with graph extensions, null checks, type casting, and error handling.

PXUIVerify Attribute

The same validation using PXUIVerify directly on the DAC:

One attribute replaces 30+ lines of event handler code.

When Validation Triggers

According to the Acumatica documentation, a field is verified when one of the following events occur:
