Do you have space between %> and input:checked or not?

Your code should like this

$(function(){ 
    $("#<%=btnSave.ClientID %>").click(function(){
          var v=$("#<%=rdTax.ClientID %> input:checked").length;
          if(v==0)
             alert('Not checked any radio button');
     }); 
});

or better you can try this

$(function(){ 
    $("[id$=btnSave]").click(function(){
          var v=$("[id$=rdTax]").find("input:checked").length;
          if(v==0)
             alert('Not checked any radio button');
     }); 
});

Use length to check if any radiobutton is checked ,length would be zero if no button is selected

$('input[type=radio][name=radiobuttonlistID]:checked').length

and use prop to check or uncheck them

$('input[type=radio][name="radiobuttonlistID"]').prop('checked', false);

Easy way to validate a radio button set the default selection of radio button when you want. I think this is a best way to validate radio button.

If you want to use jquery validation plugin see a link:
