Introduction

AJAX SubForm gives you the flexibility of dynamically loading a Subform by attaching a listener to another form field. 

Data to load by the AJAX Subform

The target's form Load Binder will be executed to fetch record matched from the properties defined in AJAX Subform.

The Advanced Grid is only available on Professional and Enterprise Edition.
