页面代码

<div class="bookList">

    <asp:Repeater ID="rpBooks" runat="server">

        <HeaderTemplate>

            <ul class="title">

                <li class="bName">书名</li>

        <ItemTemplate>

            <ul class="data">

                <li class="bName"><%#eval_r("title").ToString().Length > 20 ? eval_r("title").ToString().Substring(0, 20)+"..." : eval_r("title").ToString()%></li>

                <li class="bAuthor"><%#eval_r("author").ToString().Length > 20 ? eval_r("author").ToString().Substring(0, 20) + "..." : eval_r("author").ToString()%></li>

            </ul>

        </AlternatingItemTemplate>

    </asp:Repeater>

<div style="clear:both;"></div>

<!--分页跳转-->

    跳转到

    <asp:TextBox ID="txtPageIndex" runat="server" Width="30px"></asp:TextBox>

<asp:Button ID="btnGo" runat="server" Text="跳转到" CommandName="btn"

        oncommand="lbtnFirst_Command" />

共<asp:Label ID="lblCount" runat="server" Text="Label"></asp:Label>

    条记录</p>

    </div>
