为循环的repeater的第一行加个样式

 <asp:Repeater ID="repSmallBottom" runat="server">
                                        <ItemTemplate>
                                            <li class="<%# (Container.ItemIndex+1)==1?"on":"" %>">
                                                <%#Eval("smallClassName") %>
                                            </li>
                                        </ItemTemplate>
                                    </asp:Repeater>
