Stages of Page Life-Cycle:

1.     Page Request: This 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.

2.     Start:

HTTPRuntime – Global.asax is parsed and compiled

PreInit – Check for IsPostback. Create dynamic controls. Set the Master page dynamically. Set Stylesheet theme property. Set culture property. Read and set the profile property values.

3.             Page Initialization:

Page_Init – Read and change control properties. Setup handlers for events. Load external template files.

LoadViewSate() – Specify how ViewState is stored. Specify how ViewState is mapped to the internal state.

4.             Load:

Page_Load – Initial binding will be performed if the page is processed for first time. Read and update control properties.

5.             Validations: Validates information assigned to validation controls.

6.     Event Handling:

Page_DataBinding – Bind data sources to controls.

Page_PreRender – Make final modifications to the page. Change the control tree structure.

SaveViewState -

7.             Rendering:

Page_Render – Make changes to the HTML of the page. Write text for controls of a page.

8.             Unload:

Page_Dispose – Discard objects used in the page.

Page_Unload – Close open files. Close open database connection. Finish logging on other request specific task.
