Questions tagged [page-lifecycle]

When a page is requested on the web the server goes through a number of stages before sending back a response. Thus, the page life cycle is runs between request to response on the server.

Main steps in lifecycle are:

  1. Page request
  2. Start
  3. Initialization
  4. Load
  5. Postback event handling (if it is a postback request)
  6. Rendering
  7. Unload
