Answer / abhishek
When a form is submitted in classic ASP, all form values
are cleared. Suppose you have submitted a form with a lot
of information and the server comes back with an error. You
will have to go back to the form and correct the
information. You click the back button, and what
happens.......ALL form values are CLEARED, and you will
have to start all over again! The site did not maintain
your ViewState.

Answer / madhunathanv
Sorry,
in the above example of declaration and calling View state
Key Name Should the same but it was not so while declaring
the key name was "ViewStateVariableName" and while calling
the key name was "ViewStateVariable" which won't work if
so, it was by mistake,
ie..,when called name was changed..,
Cool:-)
Below is the Correct Format:
**********************'
ViewState Declared As:'
**********************'
ViewState["ViewStateVariableName"] = 1;
**********************************'
Above ViewState Can be called As: '
**********************************'
int number = (int) ViewState["ViewStateVariableName"];
AFAIK

Answer / mallikarjuna
Viewstate is stored in hidden input field and sent back to
the server with every post back.
veiwstate is a concept of maintaing the controls props.
adv:
redusing the manuel coding
it can not use persistant memory in client system or server
system.
dis adv:
more amount of data can be transfered between client and
web server
configaration :
we can figure viewstate at three levels
1.pagelevel
2.control level
3.application level
cl:<input.......... enableviewstate="true[d]/false">
pl:<%@page...........enableviewstate="tr true
[d]/false"%>
al:this is required configurationfile
<pages .......... enableviewstate="true
[d]/false>

Answer / sujeet
If a site happens to not maintain a View State, then if a
user has entered some information in a large form with many
input fields and the page is refreshes, then the values
filled up in the form are lost...........

Answer / madhunathanv
ViewState is confined only to the page cycle ,
When the Viewstate is declared in the particular Method in
the Page ,it can be called in other methods or Events when
it is in Need.
ie.., it persists its state across postbacks
**********************'
ViewState Declared As:'
**********************'
ViewState["ViewStateVariableName"] = 1;
**********************************'
Above ViewState Can be called As: '
**********************************'
int number = (int) ViewState["ViewStateVariable"];
