Web server controls are an essential component of web development. They provide a way to create interactive and dynamic web applications. In this article, we will explore what web server controls are and how they can be used to enhance the functionality of your websites.

What Are Web Server Controls?

Web server controls are HTML elements that are implemented on the server side of a web application. Unlike traditional HTML elements that are rendered by the client’s web browser, web server controls generate HTML markup dynamically on the server and then send it to the client.

Advantages of Using Web Server Controls:

There are several advantages to using web server controls:

1. Rich functionality: Web server controls provide a wide range of built-in functionality that can be easily incorporated into your applications. Examples include text boxes, buttons, drop-down lists, calendars, and more.

2. Event-driven programming model: Web server controls enable developers to handle events such as button clicks or page loads. This allows for interactivity and enhances user experience.

3. Easy customization: Web server controls offer extensive properties that can be modified programmatically or through markup attributes. This allows for easy customization and enables developers to tailor the appearance and behavior of the controls according to their specific requirements.

4. Validation and data binding: Web server controls provide built-in validation features to ensure data integrity on form submissions. They also support data binding, allowing you to bind data from various sources such as databases or XML files directly to the control.

Types of Web Server Controls:

Web server controls can be categorized into two types: HTML-based controls and ASP.NET controls.

1. HTML-based Controls:

These controls resemble standard HTML elements but offer additional functionality on the server side. Some commonly used HTML-based controls include:

  • TextBox: Allows users to enter text or data.
  • Button: Triggers an action when clicked.
  • Label: Displays static text on the web page.
  • CheckBox: Represents a checkbox for selecting options.

2. ASP.NET Controls:

ASP.NET controls are more powerful and provide advanced functionality compared to HTML-based controls. Some commonly used ASP.NET controls include:

  • DataGrid: Displays data in a tabular format with built-in paging and sorting capabilities.
  • DropDownList: Presents a list of options for users to select from.
  • Calendar: Provides a calendar control for date selection.
  • LoginView: Displays different content based on the user’s login status.

Working with Web Server Controls:

To use web server controls, you need to place them within a server-side form element (

). This tells the server that the controls inside the form should be processed on the server side.

Web server controls can be accessed and manipulated programmatically using server-side code, such as C# or VB.NET. You can assign values to their properties, handle events, and perform various operations based on user interactions.

An Example: Using a TextBox Control

Let’s take a quick look at how to use a TextBox control in an ASP.NET application:



In the code above, we have a TextBox control with an ID of “txtName” and a Button control with an ID of “btnSubmit”. When the button is clicked, the server-side event handler “btnSubmit_Click” is executed.

To access the value entered in the TextBox control, you can use the `Text` property in your server-side code:

protected void btnSubmit_Click(object sender, EventArgs e)
string name = txtName.Text;
// Perform further processing with the entered name

In this example, we retrieve the value entered in the TextBox control and store it in a variable named “name”. You can then use this value for further processing within your application.


Web server controls are a powerful tool for building interactive and dynamic web applications. They provide rich functionality, event-driven programming, easy customization, and support for data binding and validation. By leveraging web server controls effectively, you can enhance user experience and create feature-rich websites.
