Many of you have probably discovered how useful the Bindings tab in the Component Inspector panel can be. In case you haven't, you can use the Bindings tab to bind data between components on the Stage. This process is briefly demonstrated in this article, and in more detail within the following articles:

I also cover data bindings in my article, Building a Tip of the Day Application (Part 2): Working with Web Services.

What you might not have tried yet is creating bindings between components using simple ActionScript instead of the Bindings tab. Adding code is often faster and more efficient than relying on the authoring environment. This article introduces you to runtime data binding, and demonstrates how to create bindings using code instead of depending on the Component Inspector and several dialog boxes.

Requirements

Flash MX 2004 or Flash MX Professional 2004

Prerequisite knowledge:

Basic knowledge of the Flash authoring environment and a basic knowledge of ActionScript.
