advantages and disadvantage of viewstae in asp.net.

kiran kumar · Answer

Advantages: - No server resources required - simple implementation - automatic retention of page and control state - Enhanced security features. The values in view state are hashed, compressed, and encoded for Unicode implementations. Disadvantages: - Performance. The view state is stoed in the page itself, so increase the page size. - Security. The view state is stoed in a hidden field on the page. Although view state stores data in a hashed format, it can be tampered with.

advantages of the ViewState 1. Simplicity. There is no need to write possibly complex code to store form data between page submissions. 2. Flexibility. It is possible to enable, configure, and disable ViewState on a control-by-control basis, choosing to persist the values of some fields but not others. Disadvantages of the ViewState 1. Does not track across pages. ViewState information does not automatically transfer from page to page. With the session approach, values can be stored in the session and accessed from other pages. This is not possible with ViewState, so storing data into the session must be done explicitly. 2. ViewState is not suitable for transferring data for back-end systems . That is, data still has to be transferred to the back end using some form of data object.
