How to change text mode to password mode after entering in textbox in asp.net
<p>I have a form in ASP.NET as below :-</p>

<pre><code>Number(textbox)
Name(textbox)
Age(textbox)
sex(textbox)
Marks(textbox)
Class(textbox)
Re enter number(textbox)
Save(button)
</code></pre>

<p>In this fields after entering number, when I go for next field number filed of textbox data of text mode should convert to password mode. after entering "re enter number" it should check for matching both "number" and "re enter number" and should display message like number is matched or not matched and then save data.</p>
