About Events and Rules

When designing your app, you often want to provide logic for when X happens do Y. Apps provides the ability for these dynamic actions:

• X is called an Event.
• Y is called a Rule.

Here are a few examples:

• When the "Submit deposit" button is clicked, run an automation.
• When the value of the "Cash In" textbox changes, change the label color to red if the value is < 0.
• When the help icon is clicked, open the browser to show a documentation page.
• When a tab button is clicked, change the page container to show a different page.

By specifying what rules to execute when an event occurs, your app transforms from being a simple display of information to an interactive console.

Events

Events are triggers that happen when a user interacts with an app or control. Each control supports a single event:

Event	Control(s)
Clicked On	Button, Header, Label, Icon, Image
Value Changed	Checkbox, Date picker, Dropdown, Slider, Switch, Text Area, Textbox, List
Loaded	Page, Table

Rules

Rules allow your app to take an action when a certain event occurs. Below is a list of the rules that Apps provides:
