What is the page life cycle in ASP.NET?

The page life cycle in ASP.NET refers to the series of processing steps that occur when an ASP.NET page is requested and processed by the server. This life cycle outlines the various stages that the page goes through from the moment a request is received until the final output is sent back to the client.

During the page life cycle, several key events are triggered, such as initialization, loading, postback handling, rendering, and unloading. Understanding these stages helps developers manage the state of controls, perform necessary data binding, and appropriately handle user inputs. It also allows for implementation of business logic and ensures efficient resource management throughout the page's lifetime.

This understanding of the page life cycle is crucial for creating dynamic and interactive web applications using ASP.NET, as it provides a framework for handling events and organizing code in a structured manner.
