Hi Mauli,

You could try this code

XML

<!DOCTYPE html>
<html>
<body>
<script language="javascript" type="text/javascript">
<!--
function validate() {
    var text = document.getElementById('txtbx').value;
    if (text == "")
    {
      alert('TextBox is empty');
      location.reload();
    }
}

//-->
</script>
<input type="text" id="txtbx"/>
<input type="button" onclick="validate();" value="Click me"/>
</body>
</html>

Hope this helps you a bit.

Regards,
RK
