HTML Server Controls - ( ASP.NET Web Forms )

In ASP.NET Web Forms, you can use HTML server controls to create dynamic web applications with user interaction and data binding. HTML server controls are wrapped under a <asp:xxx> element and are used to perform various tasks such as data input, display, manipulation, formatting, and more.

Syntax

The syntax for creating an HTML server control is as follows:

<asp:controlname id="mycontrol" runat="server" {...attributes}></asp:controlname>

Here, controlname is the name of the control, id is the unique identifier for the control, and runat="server" specifies that the control is an HTML server control. You can also specify attributes for the control using {...attributes}.

Example

Here's an example of how to create an HTML server control in ASP.NET Web Forms:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:Label ID="lblInfo" runat="server" Text="Enter your name"></asp:Label>
        <br />
        <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        <br />
        <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />
        <br />
        <asp:Label ID="lblMessage" runat="server" />
    </form>
</body>
</html>

In this example, we've created three HTML server controls: Label, TextBox, and Button. We've also added a Label control for displaying messages.

Output

The output of the above example will be a web form with a label, text box, and a button that allows you to enter your name and submit it. Upon clicking the submit button, the label will display a message that you entered in the text box.

Explanation

HTML server controls are used to build the interface of a web page in ASP.NET Web Forms. These controls handle events, store data, and display information. In the example above, the Label control is used to display a message to the user, the TextBox control is used to allow the user to enter data, and the Button control is used to submit the data to be processed.

Use

HTML server controls are used to create interactive and dynamic web pages in ASP.NET Web Forms. These controls provide a wide range of functionality, including data binding, validation, and rich formatting. They also provide a consistent look and feel across your web application.

Important Points

  • HTML server controls are wrapped under a <asp:xxx> element.
  • HTML server controls are used to perform various tasks such as data input, display, manipulation, formatting, and more.
  • You can also specify attributes for the control using {...attributes}.
