Question: What are the advantages/disadvantages of viewstate?

Answer: Advantages - On ordinary Web Forms pages, their view state is sent by the server as a hidden variable in a form, as part of every response to the client, and is returned to the server by the client as part of a postback. However, to reduce bandwidth demand when using mobile controls, ASP.NET does not send a page’s view state to the client. Instead, the view state is saved as part of a user’s session on the server. Where there is a view state, a hidden field that identifies this page’s view state is sent by the server as part of every response to the client, and is returned to the server by the client as part of the next request.

Disadvantages - Because the view state for a given page must be kept on the server, it is possible for the current state to be out of synchronization with the current page of the browser, if the user uses the Back feature on the browser to go back in the history.
