Asp. NET most commonly used page life-cycle Events

PreInit: An event that can be accessed in the early stages of the page life cycle. After the PreInit event, personalization information and page themes are loaded.

Init: Raised after all controls have been initialized and all appearance settings have been applied. Use this event to read or initialize the properties of a control.

InitComplete: Occurs when page initialization is complete.

Preload: Performs processing on the page or control before the Load event. After the page raises the event, it loads the view state for itself and all the controls, and then processes the request instance to include any postback data.

Load: Occurs when a server control is loaded into a Page object. Use the IsPostBack page property to check whether the page is processed for the first time. If this is the first process, data binding is performed.

LoadComplete: Occurs at the end of the load phase of the page's life cycle.

PreRender: Occurs after the control object is loaded and before it is rendered. The PreRender event occurs for each control on the page. Use this event to make a final change to the contents of a page or control.

Savestatecomplete: Occurs after the page finishes saving all view state and control state information for controls on the page.

Unload: Occurs when a server control is unloaded from the content. This includes operations such as cleaning up open database connections, discarding objects, or closing open files.
