前台代码如下所示：<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
    CodeFile="LookMessage.aspx.cs" Inherits="LookMessage" Title="无标题页" %><asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
    <asp:DataList ID="msgList" runat="server" Width="100%">
        <ItemTemplate>
            <div class="list">
                <div class="head">
                    <div>
                        <%# DataBinder.Eval(Container.DataItem,"Title","{0}") %>
                     </div>
                    <div class="userName">
                        留言人：<%# DataBinder.Eval(Container.DataItem,"UserName","{0}") %>
                     </div>

aspnetpager分页
this.DataList1.DataSource =ps ;DataSet ds=new DataSet();   
PagedDataSource objPage=new PagedDataSource();   
objPage.DataSource=ds.Tables["user"].DefaultView;   
objPage.AllowPaging=true;   
objPage.PageSize=6;   
int CurPage;   
if(Request.QueryString["Page"]!=null)   
CurPage=Convert.ToInt32(Request.QueryString["Page"]);   
else   
CurPage=1;   
objPage.CurrentPageIndex=CurPage-1;   
this.lblCurPage.Text="当前页：第"+CurPage.ToString()+"页";   
this.DataList1.DataSource=objPage;   
this.DataList1.DataBind();
