ASP. Net Page Life Cycle
- When an ASP.NET page runs, the page goes through a life cycle in which it performs a series of processing steps.
- These include initialization, instantiating controls, restoring and maintaining state, running event handler code, and rendering.
- It is important for you to understand the page life cycle so that you can write code at the appropriate life-cycle stage for the effect you intend.
Page Life-Cycle Stages
- Page request
- Postback event handling
- The page request occurs before the page life cycle begins.
- When the page is requested by a user, ASP.NET determines whether the page needs to be parsed and compiled (therefore beginning the life of a page),
- OR whether a cached version of the page can be sent in response without running the page
