C# Class Windows.UI.Interactivity.EventTriggerBase

Represents a trigger that can listen to an object other than its AssociatedObject.

This is an infrastructure class. Trigger authors should derive from EventTriggerBase<T> instead of this class.

Inheritance: TriggerBase

Method	Description
GetEventName ( ) : string	Specifies the name of the Event this EventTriggerBase is listening for.
OnAttached ( ) : void	Called after the trigger is attached to an AssociatedObject.
OnDetaching ( ) : void	Called when the trigger is being detached from its AssociatedObject, but before it has actually occurred.
OnEvent ( object eventArgs ) : void	Called when the event associated with this EventTriggerBase is fired. By default, this will invoke all actions on the trigger. Override this to provide more granular control over when actions associated with this trigger will be invoked.
