To manage states in an ASP.NET application, you can use the following methods:
A. Session Objects: The Session object is used to store and retrieve user-specific data across multiple web pages during a user's session. It allows you to store data that is accessible to the user throughout their visit to the website.
B. Application Objects: The Application object is used to store and retrieve data that is accessible to all users of the application. It allows you to store data that is common to all users and persists throughout the lifetime of the application.
C. ViewState: ViewState is used to store and retrieve the state of a web form between postbacks. It allows you to maintain the state of controls and their values across multiple postbacks, ensuring that user input is not lost.
Therefore, the correct answer is D) All of the above. All three options (Session Objects, Application Objects, and ViewState) can be used to manage different types of states in an ASP.NET application.
