retrieve radiobutton??

[dfetrow410]

I am using a datalist. I need to retrieve only selected values. I tried
to use the following code below with no luck. Not sure how to do the
backend

<tr>
<td align="left" valign="top"><img
src="images/vote_slectionNon.gif" alt=" " width="103" height="25"></td>
<td align="center" valign="top" width="24"
background="images/vote_selection.gif"><asp:RadioButton
ID="RadioButton2" runat="server" GroupName='<%# Eval("noID") %>,1'
/></td>
<td align="center" valign="top" width="24"
background="images/vote_selection.gif"><asp:RadioButton
ID="RadioButton3" runat="server" GroupName='<%# Eval("noID") %>,2'
/></td>
<td align="center" valign="top" width="24"
background="images/vote_selection.gif"><asp:RadioButton
ID="RadioButton4" runat="server" GroupName='<%# Eval("noID") %>,3'
/></td>
<td align="center" valign="top" width="24"
background="images/vote_selection.gif"><asp:RadioButton
ID="RadioButton5" runat="server" GroupName='<%# Eval("noID") %>,MVP'
/></td>
</tr>
