What are benefits and Limitation of using View state for state management in asp.net?
Following are the benefits of using View state:-
. 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 View state:-
. 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.
