What is View State in Asp.net?
Ans: View state is
nothing but a method that the ASP.NET use to preserve page and control
values between postbacks. When the HTML markup for the page is rendered,
the current state of the page and values that must be retained during
postback are serialized into base64-encoded strings. This information is
then put into the view state hidden field.
2). View state is client-side or server side state management technique?
Ans: View state is client-side state management technique
3). What are the client-side state management technique supported by ASP.NET?
Ans: View state
Control state
Hidden fields
Cookies
Query strings
4). View state is used by Asp.net page aromatically or we need to apply it manually?
Ans: View state is
used automatically by the ASP.NET page framework to persist information
that must be preserved between postbacks.
5). When you can use(take advantage of vs) view state?
or What you can do by use view state?
Ans: a) Keep values between postbacks without storing them in session state or in a user profile.
b) Store the values of page or control properties that you define.
c) Create a custom
view state provider that lets you store view state information in a SQL
Server database or in another data store.
6). What are the advantages of using view state?
Ans: No server resources are required : The view state is contained in a structure within the page code.
Simple
implementation : View state does not require any custom programming to
use. It is on by default to maintain state data on controls.
Enhanced security
features : The values in view state are hashed, compressed, and encoded
for Unicode implementations, which provides more security than using
hidden fields.
7). What are the limitations of view state?
Ans: Limitations:
Because view state is stored in the page, it results in a larger total page size.
ASP.NET uses view state only with page and control properties.
View state isn't a good place to store sensitive information that the client shouldn't be allowed to see.
