Repeater全选删除和分页实现思路及代码

<webdiyer:aspnetpager id="benren" runat="server" pagesize="2"
CssClass=”anpager” onpagechanged=”AspNetPager1_PageChanged”
FirstPageText=”首页” LastPageText=”尾页” NextPageText=”下一页” PrevPageText=”上一页”
ShowMoreButtons=”False” ShowPageIndexBox=”Never” AlwaysShow=”True”>

==================
