Hi i have a radiobutton list placed inside an update panel.I can get an alert with JavaScripting when the radiobuttonlist is not selected.but the problem is that when i check the radiobuttonlist and click the save button i get the same message.what's problem?.
how do i achieve this.

All suggestions are much appreciated

Thanks in advance

the javascript code given below

 <script language="javascript" type="text/javascript">
     function ValidateRadioTable()
{
var rb2 = document.getElementById('<%=rdTable.ClientID%>');
var radio_choice2 = false;
 for (counter2 = 0; counter2 < rb2.length; counter2++)
 {
  if (rb2[counter2].checked)
  {
   radio_choice2 = true;
   break;
 }
 }
 if (radio_choice2==false)
 {
  alert("Please select Table Booking Yes or No.")
    event.returnValue=false;
    return false;
 }
return false;
}

</script>

----------------------------
  <asp:RadioButtonList ID="rdTable" runat="server" AutoPostBack="True" Font-Size="10pt"
                                            RepeatDirection="Horizontal" Width="110px">
                                            <asp:ListItem>Yes</asp:ListItem>
                                            <asp:ListItem>No</asp:ListItem>

  </asp:RadioButtonList></td>

I suggest you show the HTML generated by the ASP code in regards to the radio buttons. Then we can see whether the script should work or not.
