Get posted values from radio buttons in datalist

[darkelf]

Hello
I have a aspx page with a two datalist controls. Inside them I have some radio buttons that are created with data binding for the user to choose. It displays a question and user has to choose one of the radio buttons

<asp:datalist id="studentList1" runat="server"><ItemTemplate><%# DataBinder.Eval(Container.DataItem, "cQtext") %><asp:RadioButton id="Radio1" Text="0 (Καθόλου)" Checked="False" GroupName='<%# DataBinder.Eval(Container.DataItem, "cCode") %>' runat="server" /><asp:RadioButton id="Radio2" Text="1" Checked="False" GroupName='<%# DataBinder.Eval(Container.DataItem, "cCode") %>' runat="server" /></ItemTemplate></asp:datalist

My problem is that I cannot get the user's answers in the post back code. I just need to know to which of the radiogroups the user answered which button.
Any ideas
Thank you very much in advance
Nic
