一、前台显示界面代码Default.aspx（注意,代码运行环境是VS.2005）

<%@Page Language="C#"AutoEventWireup="true"CodeFile="Default.aspx.cs"Inherits="Default4"%>

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

<htmlxmlns="http://www.w3.org/1999/xhtml">

<headid="Head1" runat="server">

<title>用AspNetPager.dll控件的分页方法操作方法</title>

</head>

<body>

<formid="form1" runat="server">

<div>

<tableborder=1>

<asp:RepeaterID="Repeater1" runat="server">

<tr>

</tr>

</ItemTemplate>

</asp:Repeater>

</table>

<webdiyer:AspNetPagerID="AspNetPager1" runat="server" Width="100%"NumericButtonCount="6"UrlPaging="true" NumericButtonTextFormatString="[{0}]" CustomInfoHTML=" 第 <font color='red'><b>%CurrentPageIndex%</b></font> 页共 %PageCount% 页显示 %StartRecordIndex%-%EndRecordIndex% 条"ShowCustomInfoSection="left"

FirstPageText="首页"LastPageText="末页" NextPageText="下页" PrevPageText="上页" Font-Names="Arial" BackColor="#F8B500" AlwaysShow="true" ShowInputBox="Always" SubmitButtonText="跳转" SubmitButtonStyle="botton" OnPageChanged="AspNetPager1_PageChanged" >

</webdiyer:AspNetPager>

<%--<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"></webdiyer:AspNetPager>

--%>

</div>

</form>

</body>

</html>

二、Default.aspx.cs页面的代码

DBAccess db =new DBAccess();

protectedvoid Page_Load(object sender,EventArgs e)

{

if (!Page.IsPostBack)

{ BindGrid(); }

}

protectedvoid AspNetPager1_PageChanged(object sender,EventArgs e)

{ BindGrid();

}

publicvoid BindGrid()

{

this.AspNetPager1.RecordCount =Int32.Parse(db.GetAllCount().ToString());

int pageIndex =this.AspNetPager1.CurrentPageIndex - 1;

int pageSize =this.AspNetPager1.PageSize = 20;

Repeater1.DataSource = db.GetCurrentPage(pageIndex, pageSize);

Repeater1.DataBind();

}

三、DBAccess.cs页面的代码

using System.Data.SqlClient;

publicclass DBAccess

{

privateSqlConnection con;

privatestring DBName = "tongjinet";

//创建连接对象并打开

publicvoid Open()

{

if (con ==null)

con = newSqlConnection("server=(local);uid=sa;pwd=sql;database=" + DBName);

if (con.State ==ConnectionState.Closed)

con.Open();

}

//创建一个命令对象并返回该对象

publicSqlCommand CreateCommand(string sqlStr)

{

Open();

SqlCommand cmd =new SqlCommand();

cmd.CommandType = CommandType.Text;

cmd.CommandText = sqlStr;

cmd.Connection = con;

return cmd;

}

//生成一个对象并返回该结果集第一行第一列

publicobject GetScalar(string sqlStr)

{

SqlCommand cmd = CreateCommand(sqlStr);

object obj = cmd.ExecuteScalar();

//CommadnBehavior.CloseConnection是将于DataReader的数据库链接关联起来

//当关闭DataReader对象时候也自动关闭链接

return obj;

}

//执行数据库查询并返回一个数据集 [当前页码,每页记录条数]

publicDataSet GetCurrentPage(int pageIndex,int pageSize)

{

//设置导入的起始地址

int firstPage = pageIndex * pageSize;

string sqlStr ="select * from outputsell order by osid desc";

SqlCommand cmd = CreateCommand(sqlStr);

DataSet dataset =new DataSet();

SqlDataAdapter dataAdapter =new SqlDataAdapter(cmd);

dataAdapter.Fill(dataset, firstPage, pageSize,"outputsell");

cmd.Dispose();

Close();

dataAdapter.Dispose();

return dataset;

}

//获得查询数据的总条数

publicobject GetAllCount()

{

string sqlStr ="select count(*) from outputsell";

object obj = GetScalar(sqlStr);

return obj;

}

//关闭数据库

publicvoid Close()

{

if (con !=null)

{

con.Close();

}

//释放资源

publicvoid Dispose()

{

if (con !=null)

{

con.Dispose();

con = null;

}
