Here is my example of what I want Hyperlink1 Hyperlink2 Hyperlink3 Hyperlink3 Hyperlink4

Answer 1

Your question is difficult to understand, but generally if you want to focus an element you need to set an event handler on the radio button so that when it's clicked another element receives focus.

    document.getElementById("myRadioButton").click = function(){
        document.getElementById("Hyperlink1").focus();
    };

If your code is being generated server side with VB.NET, then you're going to have to figure out exactly how the snippet above should be rendered.

just to provide an alternative , maybe you might want to consider using jquery to do those kind of things.

and as long as you put runat="server" on your control, you can still retrieve all the value or manipulate them on the server side.

<a href="http:www.yahoo.com">link 1</a>
<a href="http:www.yahoo.com">link 2</a>
<a href="http:www.yahoo.com">link 3</a>
<a href="http:www.yahoo.com">link 4</a>
<br />
<input type="radio" name="radio4" id="radio4" value="4" /> 4<br />

$(document).ready(function(){

    $("#radio4").click(function(){
        $("a:eq(3)").css('color','red');
        $("a:eq(3)").focus();
    });
});
