You can use it when you want store the Data when postback occur

View State is one of the most important and useful client side state management mechanism.

It can store the page value at the time of post back (Sending and Receiving information from Server) of your page.

ASP.NET pages provide the ViewState property as a built-in structure for automatically storing values between multiple requests for the same page.

View state data is encrypted and cannot be viewed with software like FireBug

Here you can get detailed description with how you can interpret (and protect) the data stored in View State.
