#Define session in asp.net code
Ĭodebehind C# Code for protected void Page_Load(object sender, EventArgs e) Second page, where you need to access the session values. Set Session values during button click protected void btnSubmit_Click(object sender, EventArgs e) Protected void btnSubmit_Click(object sender, EventArgs e) So, every time it need to serialize the data before the storing it and desterilize the data before to show the user.įollowing is the example which shows you how can you store the session value in one page and access it on another page.įirst Page // Set Session values during button click
It is because the session value stores on server memory. It makes your website slow, if you use it. Using the session, you can add variable values as well as any type of object like object of class, list, datatable etc. There is lots of other technique which is used for state management like ViewState, Cookie etc. There is default time to expire the session, you can increase and decrease it using the configuration.įirst and most important it is used to maintain the state of user data throughout the application. It provides application level state management. Basically using the session, we store the data in session and access it anywhere as per requirement. So, every previous request data goes lost and you cannot retrieve previous data. Browser does not know about previous request and data. Why Session?Īs you know that the HTTP is the stateless protocol, it means every request is taking as independent request. So, I mean to say that using the session we can store the value and access it another page or throughout the application. Session is a state management technique which is used to manage the state of page or control throughout the application.

I will explain you why we use it and how to implement in code. If you like it, share it with your friends and help this blog grow.In this article, I will demonstrate you about session in asp.net. I hope, this blog post has helped you in learning and understanding how to enable Session in Asp.net Core 6 and above. Var sessionValue = ("AnyKey") ĭon’t forget to check out: Generate QR Code in Asp.net Core with 4 Simple Steps Wrapping Up To read the session value use the below code: Now, as we have set the Session value, this value will be available throughout our application. To set the Session value use the below code: Options.IdleTimeout = TimeSpan.FromMinutes(10) įinally, add the UseSession middleware as below:īelow is how my Program.cs file looks after the Session configuration: For example – setting idle time out (meaning the session will be abandoned after a certain idle time). We can even pass the Session options in the above. Now add the below line of code to add Session above the builder.Build() function. Cached items are stored by the app instance on the server where the app is running. The Distributed Memory Cache isn’t an actual distributed cache.
The functionality of the above line of code is that it creates a default implementation of IDistributedCache. Go to the IServices collection and add the below line of code before the builder.Build() function:ī圜ache() For that, navigate to the Program.cs file in the project.ĭon’t forget to check out: Startup.cs Missing in. Now, to enable session in our Asp.net Core MVC web application we need to do some configuration. I will create an Asp.net Core 6 MVC web application by the name “SessionDemo”.īelow is the screenshot of the project folder structure.
