<input type="radio" name="selectedTool" value="age" id="rbnAge">Age

this is in client side and my question is I want to use same radio btn in server side,
so when I checked Name in Client side then I need to same Name checked in Server side as well....
It means changes in both places similary in client side or in server side....

    function validate()
    {     
    if (document.getElementById("RadioButtonList1").checked==false)
    {
    var answer = confirm ("Please confirm selection...")

C#

{
    var selected = $('#<%=RadioButtonList1.ClientID %> input:radio:checked').length;
if( selected>0){alert("valid");}
else{alert("Invalid");}
}

C#

<asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatDirection="Horizontal">
       <asp:ListItem>MALE</asp:ListItem>
       <asp:ListItem>FEMALE</asp:ListItem> </asp:RadioButtonList>
       <asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server"
           ControlToValidate="RadioButtonList1" ErrorMessage="Please Select"></asp:requiredfieldvalidator>

this is enough just add a requried filed validator give the radiobuttonlist list id as control to validate in the required field validator like the example above this would do validation both client side and server side it generates the javascript for client side
