Active Server Pages (ASP) and Active Server Pages (ASP.NET) are server-side technologies for displaying interactive web pages. ASP.NET offers developers a wide range of options in a large, diverse ecosystem of libraries and tools. Developers can also design custom libraries that can be shared with any .NET platform application.
ASP.NET also contains an authentication system for developers, which includes a database, libraries, templates for handling logins, external authentication to Google, Facebook, and other services, and more. ASP.NET may be used on all major platforms, including Windows, Linux, macOS, and even Docker, by developers.
Backend code for ASP.NET apps can be written in C#, Visual Basic, or even F#. Developers can effectively code the business logic and data access layer because of this flexibility.
ASP.NET Web Forms
Web Forms are pages which are requested by your users through their browser. HTML, client-script, server controls, and server code can all be used to create these pages. When users request a page, the framework compiles and executes it on the server, then generates the HTML markup that the browser may render. In any browser or client device, an ASP.NET Web Forms page displays information to the user.
ASP.NET Web Forms may be created with Visual Studio. Drag and drop server controls to set out your Web Forms page in the Visual Studio Integrated Development Environment (IDE). The methods, properties, and events for controls on the page, as well as the page itself, can then be readily set. These attributes, methods, and events are used to define the behaviour, appearance, and feel of a web page, among other things. We can use .NET language like Visual Basic or C# to develop server code to handle the page's logic.
Creating an ASP.NET Web Forms Project
Let's get started with the creation of ASP.NET Web Forms project as shown in the images below.
Firstly create a new project.
To create a new project, we need to select the template ASP.NET Web Application (.NET Framework). If this template is not visible in the list, scroll to the bottom of the list, and click on “Install more tools and features”, and in visual studio installer, install .NET Project and item template.
Then select the web forms option.
Add a Web Form to the Project
To add a new web form to an existing project, first, pick it, then right-click and select "Add New Item."
Select the web forms option in the left corner, then web form and press the add button.
After that, we need to click the add button to add this form to our project.
Default Files in ASP.NET Web Forms Project
After adding the form, we can see that it has been added to our project, as shown in the image below.
This form contains some default HTML code.
And the aspx.cs file also contains, the below default code.
using System;
namespace CodingNinjasWebForms
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
When we run this file in the browser, it produces no results. So, let's use this form to print a message.
ASP.NET Web Forms Example
Let's make a registration form for users. This is a simple asp.Net web forms example. To demonstrate how we can modify the existing code to create a asp.net web form.
Apart from this form, we can do a lot with this page and add controls.
