ASP.NET page life cycle explanation

There are 10 events in ASP.NET page life cycle, and the sequence is:

1. Init
2. Load view state
3. Post back data
4. Load
5. Validate
6. Events
7. Pre-render
8. Save view state
9. Render
10. Unload

Below is a pictorial view of ASP.NET Page life cycle with what kind of code is expected in that event. I suggest you read this article I wrote on the ASP.NET Page life cycle, which explains each of the 10 events in detail and when to use them.

This acronym might help you to remember the ASP.NET life cycle stages which I wrote about in the below blog post.
