本文介绍了一个使用ASP.NET和Wuqi.Webdiyer实现的新闻列表分页功能。该功能包括了前台页面展示和后台逻辑处理两部分。前台通过Repeater控件展示了新闻标题、日期，并提供了修改和删除操作链接；后台则实现了分页加载数据和页面切换时的数据重新绑定。

前台：<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

<center><h2>新闻列表</h2>
    <table border=1 cellpadding=1 cellspacing=1><tr><td>新闻标题</td><td>新闻日期</td><td colspan="2">操作</td></tr>
        <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
        <tr>
      <td> <%#DataBinder.Eval(Container.DataItem, "Ntitle")%></td>
      <td> <%#DataBinder.Eval(Container.DataItem, "NcreatTime")%></td>
      <td> <a href="newsUpdate.aspx?Nid=<%#DataBinder.Eval(Container.DataItem, "Nid")%>">修改</a> </td>
      <td> <a href="newsDelete.aspx?Nid=<%#DataBinder.Eval(Container.DataItem, "Nid")%>">删除</a></td>

       </tr>
     </ItemTemplate>
        </asp:Repeater></table>
        <br />   <br />
    <webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageSize="15" style="font-size:14px;" HorizontalAlign="Right" NumericButtonCount="6" NumericButtonTextFormatString="[{0}]" CustomInfoHTML="第 <font color='red'><b>%CurrentPageIndex%</b></font> 页共 %PageCount% 页显示 %StartRecordIndex%-%EndRecordIndex% 条" InputBoxStyle="width:24px; height:14px;" ShowInputBox="Always" SubmitButtonText=" GO " FirstPageText="[首页]" PrevPageText="[上页]" NextPageText="[下页]" LastPageText="[末页]" TextBeforeInputBox="转到第" TextAfterInputBox="页 " PagingButtonSpacing="10px" width="100%" ShowCustomInfoSection="Left" UrlPaging="true" OnPageChanging="AspNetPager1_PageChanging"></webdiyer:AspNetPager>
    </center>

后台：using Wuqi.Webdiyer;

protected void Page_Load(object sender, EventArgs e)
    {

        if (!IsPostBack)
        {
            AspNetPager1.PageSize = 10;
            AspNetPager1.RecordCount = hsbll.getNewsNum();
            HSDataBind();
        }
    }
    public void HSDataBind()
    {
        DataSet ds = hsbll.getPagerDS(AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex - 1), AspNetPager1.PageSize, "HSnews order by NcreatTime desc;");
        Repeater1.DataSource = ds;
        Repeater1.DataBind();
    }
    protected void AspNetPager1_PageChanging(object src, PageChangingEventArgs e)
    {
        AspNetPager1.CurrentPageIndex = e.NewPageIndex;
        HSDataBind();
    }
