Passing Data from Child FlexCards to Parent FlexCards in OminStudio

Pass Data From a Child FlexCard to a Parent FlexCard

Overview

After embedding a child FlexCard inside another FlexCard, you can pass data from the child to its parent as input parameters from a Custom Event action on the child. Use an event listener to execute a Set Values action to update fields on the parent.

Create a child FlexCard or select one from the FlexCards home tab.

Add a custom event to the child FlexCard:

• Drag an Action element onto the canvas.
• Set the Action Type to Event
• Set the Event Type to Custom
• Enter a name in the Event Name field.
• In the Input Parameters section, click + Add New
• Under Input Parameters enter a name for the data you want to call in the Key input field.
• Under Input Parameters enter a value to pass. Or, enter a merge field from the child's data source.
• Activate the child FlexCard.

Create the parent FlexCard or open one from the FlexCards home tab.

Create an Event Listener on the Parent FlexCard

• Drag a FlexCard element from the Build panel onto the canvas.
• Click into the FlexCard Name field and select the child FlexCard you created previously.
• In the Setup panel, click + Add New in the Event Listener section.
• Under Event Type select Custom Event.
• In the Event Name input field, enter the name of the event you created in the child FlexCard.
• In the Actions section, under Action Type select Card
• In the Actions section under Type select Set Values.
• In the new Set Values section, click + Add New.
• In the Key input field, select the data field to update.
• In the Value input field, use the {action.param} syntax to pass the data you emitted in your child FlexCard action.

To preview and test, click Preview. Click the action in the child FlexCard to update a data field in the parent.
