When developers are asked, which coding language they would prefer to use to create web pages, they would gladly say ASP. Net Development. There are obvious reasons associated with this answer. For one, developers are truly fond of ASP.Net, and they find it easy to code the most difficult stances using this language.
Most of you are aware of the fact that the data received by the server is very crucial, and this data is accessed throughout the day by the multitude of web users across the globe. This data becomes critical for the UI of a website. You will constantly need to send data from one page of the website to the other page, where the business logic is present, and that would require you to code in case you are using ASP.Net Development service. Along with storing the data, you will also need to code for functions like retrieving and using the data for certain basic purposes.
Here you will see the various tasks that you will need to define using ASP.Net. Some of the tasks have already been defined using HTML earlier, and you will just need to see how it works with ASP.Net.
Here the coding and retrieval of the data using ASP.Net services will be taught to you so that you can specifically make the necessary changes.
Sharing the Data Using ASP.Net
When you want to share data along the different web pages using ASP.Net as your coding language, you will need to work a little hard. It is definitely not as easy as it seems, but with a little coding you will get things right.
Start with getting a basic understanding of the different features that you need to implement within your own projects. Let’s take an example of a form that you will use in your project. It could follow the similar coding as you would have previously used for it. Of course, ASP.Net does some of the things differently, that you will need to look into before you begin the journey of coding.
How to Use a Form?
This is the first example chosen to help understand how ASP.Net works. Firstly, you will need to use a HTML form to enable sending and receiving data from one page to another on your web page. An action attribute will help transfer the data from one page to another. Using this form, you can get the data from a page transferred onto another page with the business logic and perform the necessary activities on the data before you display it to the users.
For example, the user is asked to enter their name, and if the name matches the condition, then the task required to be performed is performed, and the relevant action is taken.
Please enter your name below:
This will give out a simple form with an input button as well as default button. This is a default HTML code. Let’s take a look at the ASP.Net version of this code.
Please enter your name below:
You can even add the following query if you wish to with this code
Response.Redirect("~/first-page?response=done");
With this below value, you can complete the process using ASP.Net development service
@if(Request.QueryString["response"] == "done") {
The process requested has completed successfully.
}
Using this code, you can share the data which in this case is the name from one page to the other page where the business logic is present easily.
Session Variables
When you are dealing with ASP.Net, you will need to account for session variables. Once the session is over, the variables will get deleted automatically and that is why they are given preference when coding.
You don’t need to stay with the naming convention when giving a session variable and you can create unlimited numbers of session variables when using your ASP.Net coding to transfer data along web pages.
Once the user has clicked the submit button, the code that would transfer the session would be as follows.
// on the same page, you use can use Request.Form["key"];
var name = Request.Form["name"];
// now just pass this value, to a new Session variable
Session["name"] = name;
// done! Now this value is available through the website.
You don’t have any convention to write the name. If the name is already present, the code would modify or overwrite it, and then write the page as below.
if(Session["name"] != null) {
// if that value is present
var name = Session["name"].ToString();
if(name == "Secret-Name") {
// name matches
}
Response.Redirect("~/first-page.cshtml");
}
You will see that the session variables are easily cleared by the OS or by the browser. Even the user can cancel the session variables. The different methods to clear a session include.
Session abandon which cancels the session
Session clear which clears the session
Session remove which works similar to clearing the session.
So, with this session variable and data transfer code, you can easily translate data from one web page to another using ASP.Net development service.
