Configuring bindings

When a property is selected on the Bindings tab, you can further define it using the options located in the bottom pane of the Bindings tab. You can specify information such as Direction and Bound To, which you'll commonly need to specify, as well more complex properties such as Formatter and Formatter Options:

Direction Shows a list of directions that can be set for a binding. You need to select a value from the list:

In: The selected schema item is the destination of a binding. It receives a new value when the other end of the binding changes. On the Schema tab, in is represented by a left-pointing arrow.
Out: The selected schema item is the source of a binding. Whenever its value changes, the value is copied to the other end of the binding. On the Schema tab, out is represented by a right-pointing arrow.
In/Out: New data values are copied when either end of the binding changes value. On the schema tab, in/out is represented by a two-headed arrow.

Bound To Identifies the destination schema item (another component's property) to which this schema item is bound. You need to specify this value. See Defining what to bind to.

Formatter Shows a list of available formatters that determine how to display this binding. For more information, see Schema formatters.

Formatter Options Shows the Formatting Options dialog box. The settings in this dialog box are used at runtime to control formatting of data assigned from this schema item to the destination schema item that is defined in the Bound To property. These settings override the default formatting settings for the source schema item. See Schema formatters.

Index For If you create a binding for a schema item that is defined as a field of an object contained within an array, you must specify an index for the array. See Creating an indexed binding.
