The Data Controls panel comprises a hierarchical display of available business objects, including collections, attributes, and methods.
With the aid of the Data Controls panel, UI design is a series of drag-and-drop steps. The list of available UI controls appears when you drop the data object selection from the panel into the page. Only the UI controls that are appropriate to display the chosen data object will appear in the list. For example, when you drag a method from the Data Controls panel, your UI choices include button and link controls but do not include form or table controls.
In the example, when you drag the arg0 structured attribute from the Data Controls panel onto the page and select ADF Form from the context menu, you are creating a form for entering data using two attributes.
When you use the Data Controls panel to create a UI component, JDeveloper automatically creates the various code and objects needed to bind the component to the data control you selected.
