一组linkbuton 点击过后加背景，且只有一个加背景，其他的原样显示

 <div class="filter_list">
    <asp:DataList ID="dtCarTypeTop10" runat="server" RepeatColumns="7" RepeatDirection="Horizontal" ItemStyle-HorizontalAlign="left" CellPadding="0" CellSpacing="0" Width="90%" OnItemCommand="dtCarTypeTop10_ItemCommand" OnItemDataBound="dtCarTypeTop10_ItemDataBound" OnSelectedIndexChanged="dtCarTypeTop10_SelectedIndexChanged">
        <ItemTemplate>
            <div style="font-size: 14px; line-height: 30px; width: 90px;" id="divCarType" runat="server">
                <asp:LinkButton ID="lbtTypeName" runat="server" Text='<%#Eval("typename") %>' CommandName="Select" CommandArgument='<%#Eval("id") %>' OnClick="lbtTypeName_Click"></asp:LinkButton>
            </div>
        </ItemTemplate>
    </asp:DataList>
</div>

判断一下不就OK了，自己写个方法转换
