This new Kentico 10 module provides an interface for creating custom responses to return data from the database in an AJAX request.
Occasionally in JavaScript you will want to access data stored within the Kentico database. Using our JavaScript web part you can insert macros into inline JavaScript, but this isn’t possible for physical files. This module provides a method to create URLs that can be used to easily request data from a SQL or macro data source within your JavaScript files.
