What is the page life cycle in ASP.NET?

Every page created in ASP.NET goes through a series of stages. This is called the life cycle of the page in ASP.NET and the different stages are given here.

1. Page request: Whenever the user requests a page, ASP.NET analyses if it should be compiled or otherwise serve it from a cache. This is the first step/process of the page's lifecycle.
2. Start: Every page has a beginning condition and this step sets them for one particular page.
3. Initialization: In this phase, all the on-page controls are initiated and the themes start getting applied.
4. Load: The control properties are set using view state and control state properties.
5. Post back event handling: The input given by the user is handled whenever required.
6. Rendering: While using ASP.NET, it can save the view state for your page. It then writes the output of the rendering into the output stream.
7. Unload: Once all the pages are rendered, they are sent to the client. Therefore, ASP.NET unloads all input page properties and then performs clean up.
