you can try following javascript funtion :

JavaScript

function CheckRadioButton() {
            var radio = document.getElementsByName('YourRadioButtonList');
            var rFlag = 0;
            if (radio.length > 0)
            {
                for (var j = 0; j < radio[0].cells.length; j++) {
                    for (var k = 0; k < radio[0].cells[j].children.length; k++) {
                        if (radio[0].cells[j].children[k].checked == true)
                        {
                            rFlag = 1;
                        }                        
                    }
                }
            }
            if (rFlag == "0") {
                alert('Please Select');
                return false;
            } 
            return true;
        }

using jquery you can do it in this way.

JavaScript

<script type="text/javascript">
        $(document).ready(function () {           
            $("#Button2").click(function () {
                alert(checkList());
            });
        });
        function checkList() {
            var flag = true;
            $("input[id*='CheckBoxList1']").each(function () {
                if (!$(this).is(":checked"))
                    flag = false;
            });
            return flag;
        }    
    </script>

ASP.NET

<div>
  <asp:checkboxlist id="CheckBoxList1" runat="server" xmlns:asp="#unknown">
      <asp:listitem>select all</asp:listitem>
      <asp:listitem>a</asp:listitem>
      <asp:listitem>b</asp:listitem>
      <asp:listitem>c</asp:listitem>
      <asp:listitem>d</asp:listitem>
  </asp:checkboxlist>
  <input id="Button2" type="button" value="button" />
</div>
