Data Binding

I want to start the chapter with something fun (if you don’t mind associating “fun” with programming): data binding. Data binding is this cool little feature in Flex that’s quite useful and yet very easy to grasp and implement. Data binding is where the value of a thing A is dynamically determined based upon another source. For example, a Label’s text property is normally hard-coded into the application (i.e., it’s set when the program is compiled):

<s:Label text="Display this text." />
