Difference between ViewState and Hidden Field in ASP.Net with example

ViewState

ViewState is an ASP.Net state mechanism to retain data across PostBack. The data is encoded and saved in a Hidden Field.

If you save data in ViewState it will not be seen by user as it is encoded.

Hidden Field

Hidden Field is a Form control similar to TextBox but the only difference is that Hidden Field keeps the data hidden from the user.

Data stored in Hidden Field can be seen by doing a page View Source.
