I have the code below, the group name didn't work, the user can choose any more than one from radio button
<asp:ListView ID="lstActive" runat="server" OnItemDataBound="lstAllWActive_ItemDataBound">
    <ItemTemplate>
        <tr>
            <td><%# Eval("PollQuestion") %></td>
            <td>
                <asp:HiddenField ID="hdPollId" runat="server" Value='<%#Eval("PollId")%>' />
                <asp:ListView ID="lstOptionWPrecentage" runat="server">
                    <ItemTemplate>
                        <div class='col-md-4'>
                            <asp:HiddenField ID="HiddenField1" runat="server" Value='<%#Eval("Id")%>' />
                            <asp:RadioButton ID="po1" runat="server" GroupName="jhhhh" ValidationGroup="poll" />
                            <label for='po1'><%# Eval("OptionText") %> </label>
                        </div>
                    </ItemTemplate>
                </asp:ListView>
            </td>
            <td><%# Eval("PollName") %>    </td>
        </tr>
    </ItemTemplate>
</asp:ListView>
