- ## Method Details

  - ### onChanged

    void onChanged(ChangedEvent event)
    Called when a FormItem's value has been changed as the result of user interaction. This method fires after the newly specified value has been stored.

    Change/Changed notifications vs "...When" rules: the `change` and `changed` events only fire when an end user modifies a field value. If you are trying to dynamically control the visibility or enabled state of other components in response to these events, consider instead using properties such as `Canvas.visibleWhen`, `item.readOnlyWhen`, `Canvas.enableWhen` on the target component. (Similar properties are available on `FormItem`, `Canvas`, `MenuItem` and other components).

    Parameters:
      `event` - the event
