前兩天有一個(gè)簡(jiǎn)單的C/S項(xiàng)目用到分頁(yè)，因?yàn)槭荳inform下,沒有現(xiàn)成的，自己也懶得寫，就找了下，看到了ycmoon的一個(gè)控件

http://www.cnblogs.com/ycmoon/archive/2010/01/07/1640689.html

參考后，做了簡(jiǎn)化，只保留了分頁(yè)的部分，主要是點(diǎn)擊事件的Delegate，未做過(guò)多測(cè)試，有興趣的朋友可以下載源碼自行修改，如有好的建議，也可以給我反饋。 3w@live.cn ,效果如下：

控件設(shè)計(jì)界面：

設(shè)計(jì)時(shí)：

運(yùn)行時(shí)：

附帶一個(gè)取分頁(yè)數(shù)據(jù)的存儲(chǔ)過(guò)程：

Create DataBase Db_TonyPaging go use Db_TonyPaging go if exists (select 1 from sysobjects where id = object_id('DepartDemo') and type = 'U') drop table DepartDemo go /*==============================================================*/ /* Table: DepartDemo */ /*==============================================================*/ create table DepartDemo ( PKID int identity(1,1), DName nvarchar(200) null, DCode nvarchar(500) null, Manager nvarchar(50) null, ParentID int null default 0, AddUser nvarchar(50) null, AddTime datetime null, ModUser nvarchar(50) null, ModTime datetime null, CurState smallint not null default 0, Remark nvarchar(500) null, F1 int not null default 0, F2 nvarchar(300) null, constraint PK_DEPARTDEMO primary key (PKID) ) go truncate table DepartDemo go /***************創(chuàng)建54 條測(cè)試數(shù)據(jù)********************* ****************downmoo 3w@live.cn ***************/ declare @d datetime set @d=getdate() declare @i int set @i=1 while @i<=54 begin --插入一條測(cè)試數(shù)據(jù) insert into DepartDemo select '國(guó)家統(tǒng)計(jì)局房產(chǎn)審計(jì)'+Cast(@i as Nvarchar(10))+'科','0','胡不歸',0,'DemoUser',getdate(), '','1900-01-01',1,'專業(yè)評(píng)估全國(guó)房?jī)r(jià)，為老百姓謀福祉',0,'' set @i=@i+1 end go --***********分頁(yè)存儲(chǔ)過(guò)程用于SQL server2005/2008、2008R2**************************** SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO Create PROCEDURE [dbo].[ZJF_CPP_GetPagedRecordFor2005_2008] (@Table varchar(1000), --表名,多表是請(qǐng)使用 tA a inner join tB b On a.AID = b.AID @TIndex nvarchar(100), --主鍵，可以帶表頭 a.AID @Column nvarchar(2000) = '*',--讀取字段 @Sql nvarchar(3000) = '',--Where條件 @PageIndex int = 1, --開始頁(yè)碼 @PageSize int = 10, --頁(yè)大小 @Sort nvarchar(200) = '' --排序字段 ) AS DECLARE @strWhere varchar(2000) declare @strsql nvarchar(3900) IF @Sql IS NOT NULL AND len(ltrim(rtrim(@Sql)))>0 BEGIN SET @strWhere = ' WHERE ' + @Sql + ' ' END ELSE BEGIN SET @strWhere = '' END if (charindex(ltrim(rtrim(@TIndex)),@Sort)=0) begin if(@Sort='') set @Sort = @TIndex + ' DESC ' else set @Sort = @Sort+ ' , '+@TIndex + ' DESC ' end IF @PageIndex < 1 SET @PageIndex = 1 if @PageIndex = 1 --第一頁(yè)提高性能 begin set @strsql = 'select top ' + str(@PageSize) +' '+@Column+ ' from ' + @Table + ' ' + @strWhere + ' ORDER BY '+ @Sort end else begin /**//**//**//*Execute dynamic query*/ DECLARE @START_ID nvarchar(50) DECLARE @END_ID nvarchar(50) SET @START_ID = convert(nvarchar(50),(@PageIndex - 1) * @PageSize + 1) SET @END_ID = convert(nvarchar(50),@PageIndex * @PageSize) set @strsql = ' SELECT '+@Column+ ' FROM (SELECT ROW_NUMBER() OVER(ORDER BY '+@Sort+') AS rownum, '+@Column+ ' FROM '+@Table +' WITH(NOLOCK) ' + @strWhere +') AS D WHERE rownum BETWEEN '+@START_ID+' AND ' +@END_ID +' ORDER BY '+@Sort END EXEC(@strsql) print @strsql set @strsql = 'SELECT Count(1) as TotalRecords FROM ' + @Table +' WITH(NOLOCK) ' + @strWhere print @strsql EXEC(@strsql)

在WinForm項(xiàng)目中，需要設(shè)置控件的總記錄數(shù) RecordCount （由分頁(yè)存儲(chǔ)過(guò)程計(jì)算得出），和翻頁(yè)事件 winFormPager1_PageIndexChanged 。

測(cè)試源碼如下：

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Data.SqlClient; namespace DemoPager { public partial class frmMain : Form { public frmMain() { InitializeComponent(); } #region Members //總記錄數(shù) public int RecordCount = 0; private string strConn = @"Data Source=ap2/vegnet;Initial Catalog=Db_TonyPaging;Integrated Security=SSPI;"; //"Server=localhost;database=Db_TonyPaging;uid=sa;pwd=sa;"; private string strProcedure = "ZJF_CPP_GetPagedRecordFor2005_2008"; #endregion #region Methods /// <summary> /// 綁定第Index頁(yè)的數(shù)據(jù) /// </summary> /// <param name="Index"></param> private void BindDataWithPage(int Index) { winFormPager1.PageIndex = Index; //winFormPager1.PageSize = 10;; ; dgvList.DataSource = GetData(strConn, strProcedure, Index, winFormPager1.PageSize); //獲取并設(shè)置總記錄數(shù) winFormPager1.RecordCount = RecordCount; } /// <summary> /// 獲取數(shù)據(jù)源 /// </summary> /// <param name="conn"></param> /// <param name="strProcedure"></param> /// <param name="pageIndex"></param> /// <param name="pageSize"></param> /// <returns></returns> private DataTable GetData(string conn, string strProcedure, int pageIndex, int pageSize) { using (SqlConnection connection = new SqlConnection(conn)) { SqlCommand command = new SqlCommand(strProcedure, connection); command.CommandType = CommandType.StoredProcedure;//采用存儲(chǔ)過(guò)程 //存儲(chǔ)過(guò)程參數(shù) command.Parameters.Add("@Table", SqlDbType.NVarChar, 1000).Value = "DepartDemo"; command.Parameters.Add("@TIndex", SqlDbType.NVarChar, 100).Value = "PKID"; command.Parameters.Add("@Column", SqlDbType.NVarChar, 2000).Value = "*"; command.Parameters.Add("@Sql", SqlDbType.NVarChar, 3000).Value = " 1=1 "; command.Parameters.Add("@PageIndex", SqlDbType.Int, 8).Value = pageIndex.ToString(); command.Parameters.Add("@PageSize", SqlDbType.Int, 8).Value = pageSize.ToString(); command.Parameters.Add("@Sort", SqlDbType.NVarChar, 200).Value = " PKID desc"; //打開連接 if (connection.State != ConnectionState.Open) { connection.Open(); } try { //填充數(shù)據(jù) SqlDataAdapter da = new SqlDataAdapter(command); DataSet ds = new DataSet(); da.Fill(ds); //獲取總記錄數(shù) RecordCount = Convert.ToInt32(ds.Tables[1].Rows[0][0]); //返回?cái)?shù)據(jù)集 return ds.Tables[0]; } catch (SqlException err) { MessageBox.Show(err.Message); return null; ; } finally { connection.Close(); } } } #endregion #region Events private void frmMain_Load(object sender, EventArgs e) { //不自動(dòng)生成列 dgvList.AutoGenerateColumns = false; //綁定數(shù)據(jù) BindDataWithPage(1); } /// <summary> /// 翻頁(yè)事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void winFormPager1_PageIndexChanged(object sender, EventArgs e) { BindDataWithPage(winFormPager1.PageIndex); } #endregion } }
