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

Clicked OnButton, Header, Label, Icon, Image
Value ChangedCheckbox, Date picker, Dropdown, Slider, Switch, Text Area, Textbox, List
LoadedPage, Table


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