The basic steps of the ASP.NET page life cycle as below.
Start :- :-where We can set page properties such as Request, Response, IsPostBack and UICulture etc.
Page Initialization:-We have access to the Init, InitComplete and PreLoad methods in this stage
Load :-The OnLoad is the event method that fires during this stage
Validation :- You can now check the IsValid property of the control
Event handling : :- The event handling controls occurs for server like Click, SelectedIndexChanged, etc
Rendering :- This Stage we can create custom controls to override the Render method for the control
Unload :- this Stage is final event occurs first for each control
