As and pointed out, the goal is simply to transfer the contents of one control into another. Which technique to use depends on context: a web page (client-side) or a desktop/web server control (server-side). Below are concise, practical options and pitfalls to watch for.

On a web page use the input value and wire an event so updates happen when you want (live, on blur, or with an explicit copy button). Example: two source inputs and two target inputs kept in sync using addEventListener('input', …) or a single click handler to copy both values at once.

<!-- minimal HTML -->
<input id="src1">
<input id="src2">
<input id="dst1">
<input id="dst2">
<button id="copyBtn">Copy</button>

<!-- minimal JS -->
const copyBtn = document.getElementById('copyBtn');
copyBtn.addEventListener('click', () => {
  document.getElementById('dst1').value = document.getElementById('src1').value;
  document.getElementById('dst2').value = document.getElementById('src2').value;
});

If working across pages or submitting to a server, send the values via a form POST/GET or use AJAX, or persist on the client with sessionStorage/localStorage for single-page flows. For desktop frameworks (Windows Forms, WPF) the equivalent is the control text property on the server side; consult the framework docs for exact property names and binding options.

Best practices: validate and trim input before copying, avoid inserting raw HTML into a target (use text properties), debounce frequent events for performance, and ensure labels and ARIA attributes for accessibility. For web details see MDN on HTMLInputElement.value and the input event: HTMLInputElement.value, input event. For WinForms text handling see Microsoft Docs: TextBox.Text.

Use the text property and assign the value of another one to it.

Use Textbox1.text=Textbox2.text for assigning value of one textbox to another text box.
