把groupname属性设置相同的名字
孟子里的是DATAGRID控件下的单选框啊，没有DATALIST的啊
为什么这2条语句都取不到DATALIST控件里的值？
<td width="50" align="center">
<input type=radio id=RadioName name=RadioName value='<%#DataBinder.Eval(Container.DataItem,"P_ID")%>'>
</td>
          </tr>
        </table>
         </ItemTemplate>
</asp:datalist>
<input type="hidden" id=rd runat=server/> --------------------------------------------------Label1.Text = "您的是：<font color=red>"+Request.QueryString["RadioName"].ToString() +"</font>";int s1=int.Parse(((System.Web.UI.HtmlControls.HtmlInputRadioButton )DL_Main.Items[i].FindControl("RadioName")).Value); 为什么这2条语句都取不到DATALIST控件里的值？

那个DataGrid结束标记打错了，DataList是一样的，我测试通过，这个页面中只能选一个，
只要设置他们的GroupName为一样的就可以了！
