Asp.Net Web Form

Learn step by step

Introduction to ASP.NET Web Forms

ASP.NET Web Forms is a part of the ASP.NET web application framework and is included with Visual Studio. It is one of the four programming models you can use to create ASP.NET web applications, the others are ASP.NET MVC, ASP.NET Web Pages, and ASP.NET Single Page Applications.

Web Forms are pages that your users request using their browser. These pages can be written using a combination of HTML, client-script, server controls, and server code. When users request a page, it is compiled and executed on the server by the framework, and then the framework generates the HTML markup that the browser can render. An ASP.NET Web Forms page presents information to the user in any browser or client device.

Using Visual Studio, you can create ASP.NET Web Forms. The Visual Studio Integrated Development Environment (IDE) lets you drag and drop server controls to lay out your Web Forms page. You can then easily set properties, methods, and events for controls on the page or for the page itself. These properties, methods, and events are used to define the web page's behaviour, look and feel, and so on. To write server code to handle the logic for the page, you can use a .NET language like Visual Basic or C#.

ASP.NET Web Forms are:

  • Based on Microsoft ASP.NET technology, in which code that runs on the server dynamically generates Web page output to the browser or client device.
  • Compatible with any browser or mobile device. An ASP.NET Web page automatically renders the correct browser-compliant HTML for features such as styles, layout, and so on.
  • Compatible with any language supported by the .NET common language runtime, such as Microsoft Visual Basic and Microsoft Visual C#.
  • Built on the Microsoft .NET Framework. This provides all the benefits of the framework, including a managed environment, type safety, and inheritance.
  • Flexible because you can add user-created and third party controls to them.

ASP.NET Web Forms offer:

  • Powerful data binding, with great tool support.
  • Support for client-side scripting that executes in the browser.
  • Support for a variety of other capabilities, including routing, security, performance, internationalization, testing, debugging, error handling and state management.
  • Separation of HTML and other UI code from application logic.
  • A rich suite of server controls for common tasks, including data access.
