标题 三层+存储过程实现分页示例代码
内容
    前台设计：
    代码如下:
    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="paging.aspx.cs" Inherits="五二一练习.paging" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    <title></title>
    <script src="js/Jquery1.7.js" type="text/javascript"></script>
    <script type="text/javascript">
    $(function () {
    $('#txtPagination').focus(function () {
    $(this).val("");
    })
    })
    </script>
    </head>
    <body>
    <form id="form1" runat="server">
    <div>
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
    Height="336px" Width="685px">
    <Columns>
    <asp:BoundField DataField="Id" HeaderText="编号" />
    <asp:BoundField DataField="NewsTitle" HeaderText="标题" />
    <asp:BoundField DataField="NewsContent" HeaderText="内容" />
    <asp:BoundField DataField="CreateTime"
    DataFormatString="{0:yyyy-MM-dd hh:mm:ss}" HeaderText="发布时间" />
    </Columns>
    </asp:GridView>
    <asp:LinkButton ID="btnFirst" runat="server" onclick="btnFirst_Click">第一页</asp:LinkButton>
    <asp:LinkButton
    ID="btnPre" runat="server" onclick="btnPre_Click">上一页</asp:LinkButton>
    <asp:LinkButton ID="btnNext"
    runat="server" onclick="btnNext_Click">下一页</asp:LinkButton>
    <asp:LinkButton ID="btnLast" runat="server" onclick="btnLast_Click">最后一页</asp:LinkButton><asp:TextBox
    ID="txtPagination" runat="server"></asp:TextBox>
    <asp:LinkButton ID="btnSkip" runat="server" onclick="btnSkip_Click">GO</asp:LinkButton>
    </div>
    </form>
    </body>
    </html>
    首先在数据库创建存储过程
    代码如下:
    create proc usp_role_GetDateByPageIndex
    @pageSize int,
    @pageIndex int
    as
    begin
    select * from
    (
    select *,ROW_NUMBER() over(order by role_id) as rownumber from role) as tbl
    where tbl.rownumber between (@pageSize*(@pageIndex-1)+1) and @pageIndex*@pageSize
    end
    exec usp_role_GetDateByPageIndex 5,3
    在项目中添加BLL,DAL,DataAccess,MODEL层
    在DAL中写一个方法：
    代码如下:
    //自己写的方法，分页获取数据列表
    public DataTable GetListDataTable(int PageSize, int PageIndex)
    {
    SqlParameter[] parameters = {
    new SqlParameter("@PageSize", SqlDbType.Int),
    new SqlParameter("@PageIndex", SqlDbType.Int)
    };
    parameters[0].Value = PageSize;
    parameters[1].Value = PageIndex;
    return DbHelperSQL.RunProcedureDataTable("usp_role_GetDateByPageIndex", parameters);
    }
    在BLL中调用GetListDataTable：
    public DataTable GetListDataTable(int pagesize, int pageindex)
    {
    return dal.GetListDataTable(pagesize, pageindex);
    }
    在DbHelper中添加RunProcedureDataTable方法：
    public static DataTable RunProcedureDataTable(string stroreProcName, IDataParameter[] parameters)
    {
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
    DataTable dt = new DataTable();
    connection.Open();
    SqlDataAdapter sqlDA = new SqlDataAdapter();
    sqlDA.SelectCommand = BuildQueryCommand(connection, stroreProcName, parameters);
    sqlDA.Fill(dt);
    connection.Close();
    return dt;
    }
    }
    然后在后台调用即可：
    代码如下:
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    using System.Data;
    namespace 练习
    {
    public partial class paging : System.Web.UI.Page
    {
    int pagesize = 10;
    int pageindex = 1;
    protected void Page_Load(object sender, EventArgs e)
    {
    if (!IsPostBack)
    {
    ViewState["pageindex"] = 1;
    LadaData();
    GetListPageindex();
    }
    }
    private void GetListPageindex()
    {
    BLL.T_News1 bnews = new BLL.T_News1();
    int totalcount = bnews.GetRecordCount("");
    if (totalcount % pagesize == 0)
    {
    ViewState["lastpageindex"] = totalcount / pagesize;
    }
    else
    {
    ViewState["lastpageindex"] = totalcount / pagesize + 1;
    }
    }
    private void LadaData()
    {
    BLL.T_News1 bnews = new BLL.T_News1();
    DataTable dt = bnews.GetListDataTable(pagesize, Convert.ToInt32(ViewState["pageindex"]));
    this.GridView1.DataSource = dt;
    this.GridView1.DataBind();
    }
    //第一页
    protected void btnFirst_Click(object sender, EventArgs e)
    {
    ViewState["pageindex"] = 1;
    LadaData();
    }
    //上一页
    protected void btnPre_Click(object sender, EventArgs e)
    {
    int pageindex = Convert.ToInt32(ViewState["pageindex"]);
    if (pagesize>1)
    {
    pageindex--;
    ViewState["pageindex"] = pageindex;
    LadaData();
    }
    }
    //下一页
    protected void btnNext_Click(object sender, EventArgs e)
    {
    int pageindex = Convert.ToInt32(ViewState["pageindex"]);
    if (pageindex<Convert.ToInt32(ViewState["lastpageindex"]))
    {
    pageindex++;
    ViewState["pageindex"] = pageindex;
    LadaData();
    }
    }
    //最后一页
    protected void btnLast_Click(object sender, EventArgs e)
    {
    ViewState["pageindex"] = ViewState["lastpageindex"];
    LadaData();
    }
    //跳转页面
    protected void btnSkip_Click(object sender, EventArgs e)
    {
    int result;
    if (int.TryParse(txtPagination.Text, out result) == true)
    {
    ViewState["pageindex"] = txtPagination.Text.Trim();
    LadaData();
    }
    else
    {
    txtPagination.Text = "请输入合法的数字";
    }
    }
    }
    }
随便看
