- 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.
There are the following limitations 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.
For Example: Sample of storing values in view state.
ViewState["Time"] = DateTime.Now.ToString();
