13 Managing Database Application Controls
Developers can create and manage a variety of database application page controls, including page items, dynamic actions, buttons, and trees.
- Managing Page Items
 View existing page items, create new page items, and edit an item to change its appearance or behavior.
- 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.
