PAGE Object

Page and Action Triggers
Microsoft Dynamics NAV 2013

Page triggers allow you to use C/AL code to control the behavior of the system as a result of an event on the page, such as a page opening or a field changing its value. You typically use page triggers for advanced validation and logic.
Page triggers can be divided into three categories:

• General page triggers that apply to the entire page
• Field page triggers that apply to a field control on a page
• Action triggers that apply to an action on a page.

General Triggers
The following table lists triggers that apply to the entire page.

Page trigger name	Executed
OnInit Trigger	When the page is   loaded, but before the controls are available.
OnOpenPage Trigger	When the page is   initialized and the controls are available.
OnClosePage Trigger	When the page about to   close and after OnQueryClosePage Trigger trigger.
OnFindRecord Trigger	When the page is   opened and a record is retrieved from a table.
OnNextRecord Trigger	When the page changes   from displaying one record to another record in a table. For example, on a   Customer card page, this happens when a user selects Next (Ctrl+Page   Down) or Previous (Ctrl+Page Up).
OnAfterGetRecord Trigger	When a record has been   retrieved but not yet displayed.
OnNewRecord Trigger	When a new record has   been initialized but not yet displayed.
OnInsertRecord Trigger	When a new record is   about to be inserted in the table.
