use client side script like javascript/jquary

JavaScript

$(document).ready(function() {
        $('#<%=myText.ClientID%>').change(function(){
           // do something 
         });
     });

Use textbox OnKeyPress Event instead that.....using javascript

JavaScript

function myFunction()
{
alert("You pressed a key inside the input field");
}
</script>

HTML

<p>A function is triggered when the user is pressing a key in the input field.</p>

<input type="text" onkeypress="myFunction()">

see online demo.. onkeypress Event[^]

you can use jquery onchange /javascript.
