Display n numbers of table in asp net webform based on user input

ASP.NET is a powerful programming language that allows developers to create dynamic and web applications. One common requirement in web development is to display a of numbers based on user input. In this article, we will explore how to achieve this using ASP.NET WebForms.

To begin, let's create a ASP.NET WebForm with a TextBox and a control. The TextBox will be used for user input, and the Button will trigger the display of the table. Here is the code for the WebForm:

    Display Table


In the code above, we have a TextBox control with the ID “txtNumber” and a Button control with the ID “btnDisplay”. The Button has an event handler “btnDisplay_Click” associated with it, which will be triggered when the button is clicked.

Now, let's move on to the code- file (Default.aspx.cs) to implement the logic for displaying the table. Here is the code:

using System;
using System.Web.UI;

    public partial class Default : Page
        protected void btnDisplay_Click(object sender, EventArgs e)
            int n = Convert.ToInt32(txtNumber.Text);

            for (int i = 1; i ");
" + i + "
"); } } }

In the code above, we first retrieve the user input from the TextBox control and convert it to an integer using the Convert.ToInt32() method. We then use a for loop to from 1 to the user input value and generate the table rows dynamically using the Response.Write() method.

Let's break down the code with some explanations:

Retrieving User Input

The line int n = Convert.ToInt32(txtNumber.Text); retrieves the value entered by the user in the TextBox control and converts it to an integer. This value represents the number of rows we want to display in the table.

Generating Table Rows

The for loop for (int i = 1; i iterates from 1 to the user input value. Inside the loop, we use the Response.Write() method to generate the table rows dynamically. The line Response.Write("" + i + ""); generates a table row with a single cell containing the current value of the loop variable.

Finally, we close the table by writing .

To see the output, run the ASP.NET WebForm and a number in the TextBox. Click the "Display" button, and you will see a table with the specified number of rows displayed on the page.

In conclusion, we have solved the of displaying a table of numbers in ASP.NET WebForms based on user input. By using the TextBox control to retrieve user input and dynamically generating table rows using the Response.Write() method, we can create a dynamic and interactive web application.
