have included html .aspx page above? have there not going work. itemtemplates not form columns, included within templatefield columns.

example (adapted code,
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.templatefield.itemtemplate.aspx
, http://msdn.microsoft.com/en-us/library/aa479353.aspx):

<asp:gridview id="gridview1" runat="server"      <columns>          <asp:templatefield headertext="description">             <itemtemplate>                 <asp:label id="label3" runat="server" text='<%# eval("description") %>'>             </itemtemplate>         </asp:templatefield>          <asp:templatefield headertext="choice">             <itemtemplate>                 <asp:radiobuttonlist id="radiobuttonlist1" repeatdirection="horizontal" runat="server" onselectedindexchanged="changed"  autopostback="true" >                     <asp:listitem value="agree" selected="true" />                     <asp:listitem value="disagree" />                     <asp:listitem value="strongagree" />                     <asp:listitem value="strondisagree" />                 </asp:radiobuttonlist>             </itemtemplate>         </asp:templatefield>      </columns> </asp:gridview>

you'll need separate templatefield definition each column.
