State Management an" ASP.NETpage (ife !ycle are the two important termswhich are common in ASP.NET ob interview

ASP.NET Page (ife !ycle

"hen a page is re&uested% it is loaded into the server memory% processed% and

sent to the browser. Then it is unloaded from the memory. At each of these steps%

methods and events are available% which could be overridden according to the

need of the application. )n other words% you can write your own code to override

the default code.

The Page class creates a hierarchical tree of all the controls on the page. All the

components on the page% e#cept the directives% are part of this control tree. 5ou

can see the control tree by adding trace6 7true7 to the page directive. "e will

cover page directives and tracing under 8directives8 and 8event handling8.

The page life cycle phases are-

)nitiali2ation

)nstantiation of the controls on the page

9estoration and maintenance of the state

E#ecution of the event handler codes

Page rendering:nderstanding the page cycle helps in writing codes for ma*ing some speci;c

thing happen at any stage of the page life cycle. )t also helps in writing custom

controls and initiali2ing them at right time% populate their properties with view0

state data and run control behavior code.

Page reuest0 "hen ASP.NET gets a page re&uest% it decides whether to

parse and compile the page% or there would be a cached version of the

page= accordingly the response is sent.

Starting o( page i(e c)ce 0 At this stage% the 9e&uest and 9esponseobects are set. )f the re&uest is an old re&uest or post bac*% the )sPost>ac*

property of the page is set to true. The !ulture property of the page is also

set.

Page initiai/ation0 At this stage% the controls on the page are assigned

uni&ue )1 by setting the :ni&ue)1 property and the themes are applied.


5/8

Pre$nit0 Pre)nit is the ;rst event in page life cycle. )t chec*s the )sPost>ac*

property and determines whether the page is a postbac*. )t sets the themes

and master pages% creates dynamic controls% and gets and sets pro;le

property values. This event can be handled by overloading the ?nPre)nit

method or creating a Page@Pre)nit handler.

$nit0 )nit event initiali2es the control property and the control tree is built.

This event can be handled by overloading the ?n)nit method or creating a

Page@)nit handler.

$nitCompete0 )nit!omplete event allows trac*ing of view state. All the

controls turn on view0state trac*ing.

Loa"ViewState0 (oadiewState event allows loading view state

information into the controls.

Loa"Post4ata0 1uring this phase% the contents of all the input ;elds are

de;ned with the formB tag are processed.

PreLoa"0 Pre(oad occurs before the post bac* data is loaded in the

controls. This event can be handled by overloading the ?nPre(oad method

or creating a Page@Pre(oad handler.

Loa"0 The (oad event is raised for the page ;rst and then recursively for all

child controls. The controls in the control tree are created. This event can be

handled by overloading the unloads method or creating a Page (oad

handler.

Loa" Compete0 The loading process is completed% control event handlers

are run% and page validation ta*es place. This event can be handled by

overloading the ?n(oad!omplete method or creating a Page@(oad!omplete

handler

Preten"er0 The Pre9ender event occurs ust before the output is rendered.

>y handling this event% pages and controls can perform any updates before

the output is rendered.

Pre2en"erCompete0 As the Pre9ender event is recursively ;red for all

child controls% this event ensures the completion of the pre0rendering phase.

SaveStateComplete0 State of control on the page is saved.

Personali2ation% control state and view state information is saved. The 'TM(

mar*up is generated. This stage can be handled by overriding the 9ender

method or creating a Page@9ender handler.

UnLoad0 The :n(oad phase is the last phase of the page life cycle. )t raises

the :n(oad event for all controls recursively and lastly for the page itself.
