# Form life cycle

Since version 4.3 form definitions support events. In version 4.3 we only supported the "On form open" event but since 4.5 we support a number of new events.

Currently supported form definition events:

* On form open
* On form created
* On form saved
* On new form saved
* On form updated
* Before form saved
* Before form deleted

### When are events triggered

Below are three scenarios shown and when the events are triggered. All the steps are color coded.

**Blue**: actions which take place on the client (Web or app)

**Light blue**: conditions

**Yellow**: Are the events, when an event is executed all related action (Linked fields, calculations, action flows) are executed before the flow continues

**Green**: server side actions
