14 Managing Database Application Controls

Developers can create and manage a variety of database application page controls, including page-level items, dynamic actions, buttons, and trees.

• Managing Page-Level Items
  An item is part of an HTML form. Examples of page-level item include a check box, a date picker, plain text, a file browse field, a popup list of values, a select list, a text area, and so on.
• Managing Dynamic Actions
  Dynamic actions enable developers to define complex client-side behavior declaratively without the need for JavaScript.
• Managing Buttons
  You can use buttons to direct users to a specific page or URL, or to post or process information (for example, by creating Create, Cancel, Next, Previous, or Delete buttons). You can also configure buttons to display conditionally or warn users of unsaved changes.
• Managing Trees
  Trees to display hierarchical information in a clear, easy-to-use format. You can create a tree control using a SQL query.
• About Incorporating JavaScript into an Application
  Oracle Application Express includes multiple built-in interfaces especially designed for adding JavaScript.
