Hi
You must use form JavaScript.
For hide a element by JavaScript you can use from bellow code:

JavaScript

<script type="text/javascript">
    function YourFunctionName() {
        document.getElementById('YourTextBoxID').style.visibility = 'hidden';
        return true;
    }
</script>

For showa element by JavaScript you can use from bellow code:

JavaScript

<script type="text/javascript">
    function YourFunctionName() {
        document.getElementById('YourTextBoxID').style.visibility = 'visible';
        return true;
    }
</script>

For call this function you can use from bellow code:

C#

Radio1<input type="radio" id="TestRadio1" name="RadioName1" value="RadioButton1"  önclick="return YourFunctionName();" />

I hope it's helpful for you.
