Event Life cycle of ASP.NET 2.0

• PreInit: 
  
  This event represents the entry point of the page life cycle. If you need to change the Master page or theme programmatically, then this would be the event to do so. Dynamic controls are created in this event.
  
• Init:
  
  Each control in the control collection is initialized.
  
• InitComplete* :
  
  Page is initialized and the process is completed.
  
• PreLoad*:
  
  This event is called before the loading of the page is completed.
  
• Load:
  
  This event is raised for the Page and then all child controls. The controls properties and view state can be accessed at this stage. This event indicates that the controls have been fully loaded.
  
• LoadComplete*:
  
  This event signals indicates that the page has been loaded in the memory. It also marks the beginning of the rendering stage.
  
• PreRender:
  
  If you need to make any final updates to the contents of the controls or the page, then use this event. It first fires for the page and then for all the controls.
  
• PreRenderComplete*:
  
  This event is called to explicitly state that the PreRender phase is completed.
  
• SaveStateComplete*:
  
  In this event, the current state of the control is completely saved to the ViewState.
  
• Unload:
  
  This event is typically used for closing files and database connections. At times, it is also used for logging some wrap-up tasks.
  

Note: The events marked with * have been introduced in ASP.NET 2.0.
