Creating runtime data bindings using
ActionScript
If you use components to create applications, it’s often necessary to add bindings between
those components so that you can interact with data or have components interact with each
other. Interaction between components is necessary for creating usable forms or interfaces that
your users can interact with. You can use the Bindings tab in the Component inspector to add
bindings between components on the Stage. You can use the Bindings tab in the Component

For more information on using the Bindings tab, see “Working with bindings in the Bindings
