What is state management in asp net?

ASP. NET is an open-source framework for building web apps on the .NET (dot NET) framework. Microsoft created it, and version 1.0 was released in 2002 to allow developers to build dynamic web apps, services, and sites. The framework is built to work with the standard HTTP protocol, which is used across all web applications.

It is built on the Common Language Runtime (CLR), allowing the use of any .NET language, including C# (object-oriented), F# (functional first), and VB. NET (a legacy of Visual Basic, used widely by about ten million coders between 1991 and 2001), and less frequently, C++ and CLI implementations of Python and Ruby.

There are two major branches of ASP. NET, called ASP. NET MVC and the more “vanilla” version called Web Forms. The former is one of the most widely used implementations of the Model-View-Controller Pattern. This decouples controllers (handle requests and map to logic), models (implement logic), and views (current output), which makes it easier to maintain and modify code in a modular design. Now, in the article we might discuss about state management in asp net

Is ASP.net and .Net the same? 

No, they aren’t the same, but they are closely related.

.NET is a runtime, set of associated tools, and language enhancements that diverged from the .NET Framework soon after Framework 4.5. Strictly speaking, frameworks aren’t compatible with one another, but (starting from Framework 4.6 and Core 2. something), they’re both compatible with .NET Standard. (This is just an API – there’s no Standard runtime.) So, you can put shared business logic in a Standard library and reference it from apps running on either Framework or Core.

Both Frameworks support web, console, and desktop applications. (Desktop support in Core is a little shaky.)

One significant difference is that the .NET Framework runs only on Windows, while .NET Core is cross-platform – Windows, Mac, Linux. Now let’s discuss state management in general. 

What is state management? 

State management refers to managing the state of more than one user interface control system consisting of radio controls, action buttons, input fields, and many more. It is a programming language used in a single UI control state entirely or partially, depending upon the condition of all other UI controls. 

What is state management in ASP.NET? 

In an ASP NET application, state management refers to an object and preserves type state control. This happens because ASP NET applications are stateless. In ASP NET, the users’ information is stored and maintained in a safer place until the user session ends. 

ASP.NET does this using session start or application state, which persists the data in the state server; the config for the state server can be found on the web. Config by default. Its value is Inproc which is stored on the same application server. 

What are the state management techniques in asp net? 

State management is divided into a technique used to manage an object’s state on different requests. It is essential to address the state in any web application. There are two types of state management systems in ASPNET.

  • Client-side state management
  • Server-side state management
  1. Client Side State Management
  • Using Hidden Fields

Code Example :

  1. int UserID=88720 
  2. HiddenField1.Value = UserID.ToString(); 
  • View state

Code Example :

  1. On Page 1: ViewState[“UserID”]=88760 ; 
  2. On-Page 2:Int UserID = Convert.ToInt32(ViewState[“UserID”]); 
  • Cookies

Code Example : ( By Using Persistence Cookie )

  1. Response.Cookies[“ProductID”].Value = PGH1450; 
  2. Response.Cookies[“ProductID”].Expires = DateTime.Now.AddSeconds(10);  

It will not be deleted Until it expires.

Code Example : ( By Using Non-Persistence Cookie )

  1. Response.Cookies[“UserSession”].Value = “Enabled”; 

It will be deleted after the user closes the Browser

  • Reading Cookie
  1. if (Request.Cookies[“ProductID”] != null) 
  2. String Val= Request.Cookies[“ProductID”].Value; 
  3. Server-Side management 

By Using Sessions

  1. Session[“UserID”] = 434235 // Set Value To Session 
  2. String UserID = Session[“UserID”].ToString(); //Get Value from the Session  

Session Start is called whenever New User Make Request opens in Browser. 

Session End Event is called automatically when Session expires or Session. Abandon ()

What is the difference between the session state and cookies in ASP NET? 

One big difference is that while one should completely stay away from using the session state, one can’t live today without cookies. The session state is stored on the machine it was created on. So, if you have multiple devices serving the same site, the chances are you store something on one server, and the user gets serviced by the other.

Also, the session state is synchronous. It means that as soon as you use it, your server will start running requests needing session state sequentially (one after another) rather than parallel (all at once). This is especially bad if you have a lot of ajax requests in your application.

Suggestion: Learn to completely turn off the session state in all applications you make and then forget that it ever existed.

On the other hand, cookies are stored by the user’s browser. Thus, a cookie stored on one server will be available for the other. Just don’t ever trust a cookie is available. Also, it’s effortless for anyone to change their content, making them not so friendly a way to store security-related information. However, every authentication method nowadays holds the user’s identity in the cookies. The contents are encrypted, making tampering with them not worth the effort.

How many types of cookies are there in ASP NET? 

There are two types of cookies asp.net

  1. Persistent Cookie: – A cookie that stores your information in your hard disk will be held until time either you will not delete that or the cookie period does not expire. It is an independent browser cookie.
  2. Non – Persistent Cookie (Temporary cookie):- A cookie that will be alive until your browser is active; as you log out to your browser or close your browser, a cookie will expire, and user information will also be lost. So it is a browser-dependent cookie,
