General Page Life-cycle Stages
Stage Page request Description The page request 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 or whether a cached version of the page can be sent in response without running the page. In the start step, page properties such as Request and Response are set. At this stage, the page also determines whether the request is a postback or a new request and sets the IsPostBack property. Additionally, during the start step, the page's UICulture property is set. During page initialization, controls on the page are available and each control's UniqueID property is set. Any themes are also applied to the page. If the current request is a postback, the postback data has not yet been loaded and control property values have not been restored to the values from view state. During load, if the current request is a postback, control properties are loaded with information recovered from view state and control state. During validation, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page. If the request is a postback, any event handlers are called. Load Rendering Before rendering, view state is saved for the page and all controls. During the rendering phase, the page calls the Render method for each control, providing a text writer that writes its output to the OutputStream of the page's Response property. Control events Unload Unload is called after the page has been fully rendered, sent to the client, and is ready to be discarded. At this point, page properties such as Response and Request are unloaded and any cleanup is performed. LoadComplete Page Event PreInit

Common Life-cycle Events
Typical Use Use this event for the following: • Check the IsPostBack property to determine whether this is the first time the page is being processed. • Create or re-create
