Services

Event Model

In general, Merchello follows Umbraco's service event model in that most services expose:

Name	Description
Creating	Occurs before create
Created	Occurs after create
Saving	Occurs before saving
Saved	Occurs after saved
Deleting	Occurs before deleting
Deleted	Occurs after delete

  protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
  {
      StoreSettingService.Saved += StoreSettingServiceOnSaved;
