What are benefits and Limitation of using Viewstate for state management?
✍: Guest
Following are the benefits of using Viewstate :-
No server resources are required because state is in a structure in
the page code.
Simplicity.
States are retained automatically.
The values in view state are hashed, compressed, and encoded, thus representing
a higher state of security than hidden fields.
View state is good for caching data in Web frame configurations because the
data is cached on the client.
Following are limitation of using Viewstate:-
Page loading and posting performance decreases when large values are
stored because view state is stored in the page.
Although view state stores data in a hashed format, it can still be tampered
because it is stored in a hidden field on the page. The information in the
hidden field can also be seen if the page output source is viewed directly,
creating a potential security risk.
Below is sample of storing values in view state.
this.ViewState["EnterTime"] = DateTime.Now.ToString();
