Which of the following events is not available in Screens or Blocks?

The event that is not available in Screens or Blocks is "After Fetch."

In OutSystems, Screens and Blocks have specific events that help manage the lifecycle and interactions within the user interface. The "Initialize" event is triggered when a Screen or Block is initialized, allowing developers to set up default values or perform necessary operations right at the start.

The "Ready" event follows the "Initialize" event and indicates that the Screen or Block is fully loaded and ready for user interaction. This is useful for executing any scripts or activating UI elements that rely on the full rendering of the interface.

The "Render" event occurs just before the final HTML of the Screen or Block is sent to the client. This stage allows last-minute modifications to the interface before it becomes visible to users.

In contrast, "After Fetch" is typically associated with data actions or aggregates and is used to reference the completion of a data fetch operation. It is not specifically tied to the lifecycle events of Screens or Blocks, making it the correct choice as the event that does not belong to those components.
