A trigger is a condition that causes an event to fire. Triggers can be based on conditions that are created:
The Event Triggers form is used to set conditions of the second type.
To create an event trigger:
From the Event Name drop-down list, select the event for which you want to define a trigger.
NOTE: You cannot define a trigger for a framework (Core) event.
On the Trigger tab, in the Condition field, enter the condition for which the event is to fire.
For more information about defining conditions, see "About Event Triggers" in the Guide to the Application Event System.
On the Parameters tab, enter the name and values for any event parameters for which you need to pass values to the event handlers when the event fires.
For more information about event parameters see "Framework Events" in the Guide to the Application Event System.
Set other options on this form as desired.
For more information on other form options see the online Help for each field.
