Building a User Registration Form in ASP.NET Web Forms: A Step-by-Step Guide

Learn how to create a functional user registration form in ASP.NET Web Forms. This tutorial provides a step-by-step guide, covering adding controls, handling form submission using C# code-behind, and processing user input, providing a practical example for building interactive web forms.

Creating a User Registration Form in ASP.NET Web Forms

Adding a Web Form and Controls

To create a user registration form in ASP.NET Web Forms, start by adding a new web form to your project. This will contain default HTML code. You then add the necessary controls (text boxes, radio buttons, checkboxes, etc.) to the form. This can be done either by dragging and dropping controls from the Visual Studio toolbox or by manually writing the code.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebControls.aspx.cs" Inherits="WebFormsControlls.WebControls" %>
<!-- Add your controls here (e.g., TextBoxes, RadioButtons, CheckBoxes, Button) -->

Handling the Submit Request (Code-Behind)

The server-side code (in the code-behind file, typically WebControls.aspx.cs) handles the form submission. When the user clicks the submit button, the code processes the submitted data.

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebFormsControlls
{
public partial class WebControls : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e) { }
protected void Button1_Click(object sender, EventArgs e)
{
    // Code to handle form submission (display a message, save data to database, etc.)
    message.Text = "Hello " + username.Text + " ! ";
    message.Text += " You have successfully registered with the following details.";
    // ... (rest of the code to display user details) ...
}
}
}

(The original text includes the complete C# code for handling the form submission, including displaying the entered user details. This code would be included in the HTML.)

Running the User Registration Form

To run the form, right-click on the WebControls.aspx file in Visual Studio and select "View in Browser".
