## 13 Managing Application Controls

Developers can create and manage a variety of 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.
