WinForm 里面的DataGridView不像WebForm里面的GridView那样有自带的分页功能，需要自己写代码来实现分页，效果如下图： 分页控件

56 private DataTable GetData(string conn, string strProcedure, int pageIndex, int pageSize)
57 {
58
59 using (SqlConnection connection = new SqlConnection(conn))
60 {
61 SqlCommand command = new SqlCommand(strProcedure, connection);
62 command.CommandType = CommandType.StoredProcedure;//采用存储过程
63 command.Parameters.Add("@Table", SqlDbType.NVarChar, 1000).Value = "TableName";//对应的数据表名

68 command.Parameters.Add("@PageSize", SqlDbType.Int, 8).Value = pageSize.ToString();//每一页显示的行数
69 command.Parameters.Add("@Sort", SqlDbType.NVarChar, 200).Value = " Column Name asc";//排序的字段
70 //打开连接
71 if (connection.State != ConnectionState.Open)
72 {
73 connection.Open();
74 }
75 try
76 {
77 //填充数据
78 SqlDataAdapter da = new SqlDataAdapter(command);
79 DataSet ds = new DataSet();
80 da.Fill(ds);
81 //获取总记录数
82 RecordCount = Convert.ToInt32(ds.Tables[1].Rows[0][0]);
83 //返回数据集
84 return ds.Tables[0];
85
86 }
87 catch (SqlException err)
88 {
89 MessageBox.Show(err.Message);
90 return null; ;
91 }
92 finally
93 {
94 connection.Close();
95 }
96 }
97 }
98
99 private void allenPage1_PageIndexChanged(object sender, EventArgs e)
100 {
101 BindDataWithPage(allenPage1.PageIndex);
102 }
103 }
104 }
存储过程：
1 IF EXISTS(SELECT * FROM SYSOBJECTS WHERE NAME='PageTest')
2 DROP PROC PageTest
3 GO
4 CREATE PROCEDURE [dbo].[PageTest]
5 @Table VARCHAR(1000), --表名,多表是请使用 tA a inner join tB b On a.AID = b.AID
6 @TIndex NVARCHAR(100), --主键
7 @Column NVARCHAR(2000) = '*',--要查询的字段，全部字段就为*
8 @Sql NVARCHAR(3000) = '',--Where条件
9 @PageIndex INT = 1, --开始页码
10 @PageSize INT = 10, --每页查询数据的行数
11 @Sort NVARCHAR(200) = '' --排序的字段
12
13 AS
14
15
16
17 DECLARE @strWhere VARCHAR(2000)
18 DECLARE @strsql NVARCHAR(3900)
19 IF @Sql IS NOT NULL AND len(LTRIM(RTRIM(@Sql)))>0
20 BEGIN
21 SET @strWhere = ' WHERE ' + @Sql + ' '
22 END
23 ELSE
24 BEGIN
25 SET @strWhere = ''
26 END
27
28 IF (charindex(LTRIM(RTRIM(@TIndex)),@Sort)=0)
29 BEGIN
30 IF(@Sort='')
31 SET @Sort = @TIndex + ' DESC '
32 ELSE
33 SET @Sort = @Sort+ ' , '+@TIndex + ' DESC '
34 END
35 IF @PageIndex < 1
36 SET @PageIndex = 1
37
38 IF @PageIndex = 1
39 BEGIN
40 SET @strsql = 'SELECT TOP ' + str(@PageSize) +' '+@Column+ ' FROM ' + @Table + ' ' + @strWhere + ' ORDER BY '+ @Sort
41 END
42 ELSE
43 BEGIN
44
45 DECLARE @START_ID NVARCHAR(50)
46 DECLARE @END_ID NVARCHAR(50)
47 SET @START_ID = convert(NVARCHAR(50),(@PageIndex - 1) * @PageSize + 1)
48 SET @END_ID = convert(NVARCHAR(50),@PageIndex * @PageSize)
49 SET @strsql = ' SELECT '+@Column+ '
50 FROM (SELECT ROW_NUMBER() OVER(ORDER BY '+@Sort+') AS RowNum,
51 '+@Column+ '
52 FROM '+@Table +' WITH(NOLOCK) ' + @strWhere +') AS D
53 WHERE RowNum BETWEEN '+@START_ID+' AND ' +@END_ID +' ORDER BY '+@Sort
54 END
55 EXEC(@strsql)
56 PRINT @strsql
57 SET @strsql = 'SELECT Count(1) as TotalRecords FROM ' + @Table +' WITH(NOLOCK) ' + @strWhere
58 PRINT @strsql
59 EXEC(@strsql)
还有一种存储过程写法，仅供参考：
1 CREATE PROCEDURE pro_DataPageRowNumber
2 @SQL nvarchar(2000),--主句
3 @Order nvarchar(20),--排序
4 @PageIndex int,--当前页
5 @PageSize int,--每页显示数
6 @TotalRow int output--记录总数
7 AS
8 SET NOCOUNT ON;
9 declare @ExceSQL nvarchar(4000)--主句
10 declare @startRow as int--开始行
11 set @startRow=(@PageIndex-1)*@PageSize+1
12 declare @lastRow int--结束行
13 set @lastRow=@PageSize*@PageIndex
14 declare @RowNumber nvarchar(100)
15 set @RowNumber=',Row_NUMBER() OVER(ORDER BY '+@Order+') as RowNumber from '
16 set @SQL=Replace(@SQL,' from ',@RowNumber)
17 set @ExceSQL='select @TotalRow=max(RowNumber) from ('+@SQL+') as tmp'
18 execute sp_executesql @ExceSQl,N'@TotalRow in output',@TotalRow output
19 set @ExceSQL='select * from('+@SQL+') as tmp where RowNumber between'+ Convert(nvarchar,@startRow)
20 +' and '+Convert(nvarchar,@lastRow)
21 execute(@ExceSQL)
22
23 GO
分页的控件是自己写的一个用户控件，生成之后是一个DLL文件，直接引用在项目里面即可，有需要的可以留下邮箱。
