difference between viewstate and session in asp.net

Hello Shanky,

ViewState can be used if you want to store data between post back of same page

but if you want to send or Store data across pages

for eg :-- if you want to pass data from one page to another page you will have to use Session, for this eg Viewstate will not work.

It is recommended to use session when there is need of data passing across pages and view state is recommended when you want to store data temporarily during postback of the same page.

Eg1) Sometimes ,Login UserId requires for all Pages..
Here U go for Session..

2)Some data cant be accessible when move to new functions/methods in same Page.
So store in Viewstate so that u can access from all functions throughout the page(Page level)...

Viewstate can be used at Page level whereas session used at Application level.
Viewstate stored in hidden field whereas session stored in memory.

1)Big values like datasets should not be saved in viewstate as they may tend to slow down the performance of the web page.
so u can switch over to session in this kind of situation alone for Page level..

For storing small values in Page level u can be use Viewstate.


2 even if a user sits on a page for an hour, then clicks somewhere, the page will still maintain the viewstate, while the Session will probably have expired

Viewstate can be used to pass values within the page, but session can be used to pass values across pages within your project.
