Actions and messages reference

Here you can find the reference for the actions you can use with triggers in Kanzi Studio. To learn about triggers, see Using triggers.

Activity Host actions

Use the Activity Host actions to set an Activity Host to activate or deactivate a specific Activity.

Name	Description
Activate Activity	Activates the child Activity that you set in this action. On successful activation, Exclusive Activity Host automatically deactivates the previously active Activity.
Deactivate Activity	Deactivates the child Activity that you set in this action. You can use this action only to deactivate an Activity in a Parallel Activity Host.

To learn about using Activities and Activity Hosts, see:

• Activities

• UI structure

Apply actions

Use an Apply action when you want to apply a value to a property or activate an Activity node only when a condition expression in an Data Trigger evaluates to true. When the condition expression in that Data Trigger no longer evaluates to true, Kanzi reverts the changes that you set in an Apply action.

You can use an Apply action only in a Data Trigger.

Name	Description
Apply Activation Action	Keeps an Activity node activated for as long as the condition expression is met in a trigger that contains this action. When the trigger condition expression is no longer met, Kanzi rolls back the state of the Activity node to the state before the action was applied. See Activating Activities with an Apply Activation Action.
Apply Property Action	Sets a property to the requested value for as long as the condition expression is met in the trigger that sets off this action. When the trigger condition expression is no longer met, Kanzi rolls back the value of that property to the value before this action was applied, or to the value set while Kanzi was applying this action.

To learn about data triggers, see Data Triggers.

To learn about the Activity nodes, see Activities.
