脚本宝典收集整理的这篇文章主要介绍了三层+存储过程实现分页示例代码脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
前台设计:
复制代码 代码如下:
@H_777_5@
<%@ 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
复制代码 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:
复制代码 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:
复制代码 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";
}
}
}
}
