Overview

When creating an application, you can configure Actionflows to respond to different events, such as a mouse click, double click or enter key press. 

Event Types and Event Handlers

An Event Handler is an action that responds to a specific event, such as a mouse click, double click or enter key press. The Event Handler defines how the application behaves when the event is triggered, such as running a  Table-action or  Actionflow.

Multiple event handlers can be set on the same component or field. For example, you may wish for a validation Actionflow to be triggered On Enter and On Blur.

Event Types and Action Settings

Worked Examples

Here's a worked example using the Shop Data (available from the Learning Centre).

In this example, we are using:

• A Shop Stock screen containing a grid of the Shop Stock data, a pie chart of the Shop Stock data and a grid of the Shop Departments data  - this screen was created using the Multi-Tile template
• A Shop Statistics screen containing 4 tiles with charts and graphs of the Shop Stock data - this screen was created using the Tile no Buttons template
• A Shop Customer Form screen containing form fields and associated with Shop Customers data by a background filter - this screen was created using the Edit Form template
