  What is ASP.NetPage Lifecycle?  Page request This stage occurs before the lifecycle begins. When a page is requested by the user, ASP.NET parses and compiles that page.  Start At this stage, the Request and Response objects are set. If the request is an old request or post back, the IsPostBack property of the page is set to true. 4/6/2022 Mr.Omeed M. M 7

  What is ASP.NetPage Lifecycle?  Initialization During page initialization, controls on the page are available and each control's UniqueID property is set. A master page and themes are also applied to the page if applicable.  Load This is when the page is actually loaded with all the default values. So if a textbox is supposed to have a default value, that value is loaded during the page load time. 4/6/2022 Mr.Omeed M. M 8

  What is ASP.NetPage Lifecycle?  Postback event handling If the request is a postback (old request), the related event handler is invoked.  Rendering This happens just before all the response information is sent to the user. All the information on the form is saved, and the result is sent to the user as a complete web page.  Unload Once the page output is sent to the user, there is no need to keep the ASP.net web form objects in memory. 4/6/2022 Mr.Omeed M.
