Introduction:
Here I will explain what is the difference between viewstate and sessionstate in asp.net using c#.net and vb.net.
Description:
In
previous posts I explained convert.tostring() VS .tostring(), web application VS website, difference between datareader,
dataadapter and dataset, difference between tinyint, smallint,
int, bigint
and many articles relating to asp.net, SQL
Server.
Now I will explain the difference between viewstate and sessionstate in asp.net
using c#.net and vb.net.
View State:
- View state is maintained in page level only.
- View state of one page is not visible in another page.
- View state information stored in client only.
- View state persist the values of particular page in the client (browser) when post back operation done.
- View state used to persist page-instance-specific data. (Read more)
Session State:
- Session state is maintained in session level.
- Session state value is available in all pages within a user session.
- Session state information stored in server.
- Session state persist the data of particular user in the server. This data available till user close the browser or session time completes.
- Session state used to persist the user-specific data on the server side. (Read more)
Usage
- If you want to access the information on different web pages, you can use SessionState
- If you want to access from the same
page, then you can use Viewstate
Security
Session state provides more security when
compared with view state as the data value is stored in server side

What is difference between viewstate and hidden fields?
Hii Jagwinder Singh,
Here is Your Answer
ViewState stores information in the Web page using hidden fields. Hidden fields are sent back to the server when the user submits a form
In view state data are store in hidden field with hash format.
Where in hidden field data is not hash.
