Example of Lifecycle Event Handlers or how they work.

Hi All,

Can any one guide me on How Lifecycle Event Handler works.?

Example on below events, Why to use, When to use, and How to use?  with little description.

On Initialize

On Ready

On Render

On After Fetch

On Parameters Changed

On Destroy


Flow Diagram  or any OML will really helpful if some one can show simple and easy use of these events. 

 
Really thanks.

Hi,

Just to highlight more about onparameter change event. 

It triggers every time you change the value of a data element of a Screen or Block and after that render event will be called. 

it will not triggers the Oninitialize or OnReady Event again.
