Standard Pages
The native user interface consists of four standard pages for working with database records. These can all be overridden, as described here:
1. Tab—The tab page appears when a custom object tab is clicked. Figure 6.5 provides an example of this page.
2. List—The list page displays a series of records in a tabular view, as shown in Figure 6.6. You reach it by clicking the Go button from the tab page.
3. View—The view page is a read-only view of a single record and its related records. Figure 6.7 is the view page for the Contact object. A page layout, determined by profile and optionally record type, is used to determine the appearance of the view page.
4. Edit—The edit page uses the same layout as the view page but allows the values of a record to be modified and saved. This is shown in Figure 6.8 for the Contact object.
Caution
Override the standard edit page with caution. The standard edit page provides deep functionality, such as page layouts and record types, that cannot be replicated in a Visualforce page without a significant amount of custom code.
To override a standard page, go to the App Setup area and click Create, Objects and select the object. Scroll to the Buttons, Links, and Actions section. Tab, view, and edit pages can be overridden only with Visualforce pages that use a standard, single record controller. The list page must use a standard set controller. Controller extensions are supported in all pages.
