Choosing to view page items
APEX Items
There are two types of APEX items: page items, which are displayed to the user on a
page, and application items, which hold values in an application but aren't displayed.
When referencing item values in queries, you should use bind variables. You may also
want to reference some of the built-in items that are available.
Page vs. Application Items
APEX page items are the UI controls that let users view and enter data—Text Field,
Textarea, Select List, Checkbox, and so on. Page items are associated with a specific
page and have UI properties associated with them; the item is displayed to the user (or
not) according to the UI properties.
Figure 6-45
shows the available APEX page item
types. See the APEX documentation for more information on page item types and their
attributes.
