What Are Two Types of Web Form Server Control?


Angela Bailey

Web forms are an essential part of any website, allowing users to input and submit data. In ASP.NET, there are two types of web form server controls: HTML controls and Web controls.

HTML Controls:
HTML controls are basic form elements that are native to HTML. These controls include textboxes, checkboxes, radio buttons, buttons, and more. They can be added to a web form using the <input> tag.

Textboxes allow users to input text or numbers. They are created using the <input type=”text”> tag. Textboxes can be customized with attributes like size, maxlength, and placeholder.

Checkboxes allow users to select one or multiple options from a list. They are created using the <input type=”checkbox”> tag. Each checkbox should have a unique name attribute.

Radio Buttons:
Radio buttons allow users to select only one option from a list. They are created using the <input type=”radio”> tag. Radio buttons with the same name attribute belong to the same group.

Buttons trigger actions on a web form such as submitting data or clearing fields. They are created using the <input type=”button”> or <button> tags.

Web Controls:
Web controls provide additional functionality compared to HTML controls. These controls are specifically designed for ASP.NET and offer more features and flexibility.

Common Web Controls:

  • TextBox: The ASP.NET TextBox control is similar to the HTML textbox but provides enhanced features like server-side events and validation.
  • CheckBox: The ASP.NET CheckBox control is an enhanced version of the HTML checkbox with additional server-side properties and events.
  • RadioButton: The ASP.NET RadioButton control is similar to the HTML radio button but offers more functionality and can be easily grouped together.
  • Button: The ASP.NET Button control provides server-side event handling and can trigger actions on a web form.

Differences between HTML Controls and Web Controls:

While both HTML controls and web controls provide similar functionality, web controls offer additional features that make them more powerful. Web controls have built-in server-side events, properties, and methods, allowing for easier data manipulation and validation. Additionally, web controls have a consistent look-and-feel across different browsers.

In conclusion, understanding the differences between HTML controls and web controls is crucial when developing web forms in ASP.NET. HTML controls are simple and lightweight, while web controls are feature-rich and provide enhanced functionality. By utilizing both types of controls effectively, developers can create dynamic and interactive web forms that enhance user experience.
