What is an hidden field?

Question

Hidden field in asp.net c#

Answer 1

HiddenField, as name implies, is hidden. This is non visual control in ASP.NET where you can save the value. This is one of the types of client-side state management tools. It stores the value between the roundtrip.
HiddenFields are not encrypted or protected and can be changed by any one. However, from a security point of view, this is not suggested.
