Difference between Synchronous and Asynchronous events

Synchronous Events

  - Fire “before” the actual events
  - You can get HttpContent
  - You can display error message
  - You can cancel the event.
  - Synchronous methods ending with “ing” like itemadding, itemupdating itemdeleting.

Asynchronous Events
  - Fire “after” the actual events
  - You cannot get HttpContent
  - You cannot display error message
  - You cannot cancel the event
  - Asynchronous methods ending with “ed” like itemadded, itemupdated, itemdeleted etc.

Happy Coding...!!!
