This is not how CP usually works. Most important goal here is to learn and help learning.
You are supposed to try it on your own, and come here when you got stuck with something, with a concrete question about your code, design, etc.
Please have a look to What have you tried?[^] to see a good explanation about what I mean.
If we give you a ready-to-go solution, it is not going to help you.

You can do it by using JavaScript :-

I. Write a Javascript function that will set your first textbox value to second textbox.
Eg.

JavaScript

function CopyText() {
           var FirstTextBox = $get('<%= txtBox1.ClientID %>');
           var SecondTextBox = $get('<%= txtBox2.ClientID %>');
           SecondTextBox.value = FirstTextBox.value;
       }

II. Now take two textbox and in first textbox, use onkeyup event to call that javascript function.
Eg.

ASP.NET

<asp:textbox id="txtBox1" runat="server" onkeyup="CopyText()"></asp:textbox>
<br />
<asp:textbox id="txtBox2" runat="server"></asp:textbox>

I hope, now you are clear.

Gool luck.

Solution 1

use text changed event and set autpostback property to true

C#

private void textBox1_TextChanged(object sender, EventArgs e)
       {
           textBox2.Text = textBox1.Text;

       }
