ASP.NET Page Life Cycle

ASP.NET Page Life Cycle

A page in an ASP.NET application consists of several server controls. These are the fundamental building blocks of an ASP.NET application.

The Life Cycle of a page when requested for the first time:

1.)Initializing: During this phase, the server creates an instance of the server control
2.)Loading: During this phase, the instance of the control is loaded onto the page object in which it is defined.
3.)PreRendering: During this phase, the control is updated with the changes made to it. This prepares the control for rendering.
4.)Saving: During this phase, the state information of the control is saved. For example, if a value is set for the control during the Load event, it is embedded in the HTML tag that will be returned to the browser.
5.)Rendering: During this phase, the server creates the corresponding HTML tag for the control.
6.)Disposing: During this phase, all cleanup tasks, such as closing files and database connections opened by the control are performed.
7.)Unloading: During this phase, all cleanup tasks, such as destroying the instances of server control are performed. This is the final event in the life cycle of a server control
