Home > Working with Application Pages > Editing a Page Definition > About the Edit All Icon
Each Page Definition is divided into three sections: Page Rendering, Page Processing, and Shared Components. Each of these sections is broken into subsections with headings that identify the type of control, component, or application logic.
You can edit all controls, components, or logic within a given subsection by clicking the Edit All icon that displays to the right of the subsection title. The Edit All icon resembles a small grid with a pencil on top of it.
Clicking the Edit All icon displays pages that enable you to edit or delete multiple controls, components, or application logic simultaneously or view a history of recent changes.
For example, selecting the Edit All icon under Regions displays a summary report of all currently defined regions on the current page. You can use this summary view to:
Edit the multiple attributes at once by making new selections from the available fields and select lists.
Link to a definition page by clicking the Edit icon.
You can access similar summary views on the next or previous page by clicking the Next and Previous buttons at top of each page. To save your edits to any summary view, click Apply Changes.
You can also view the attributes of a specific control or component by selecting its name on the Page Definition. For example, suppose your Page Definition contains a region named Customers. Clicking the region name Customers would display an attributes page for that region.
