自定义winform分页控件（转）

原文地址：/article/6381113.html http://blog.csdn.net/wanglong7505/archive/2010/01/16/5193085.aspx 效果如下： namespace WindowsApp.MyControl

ALTER PROCEDURE SP_Pagination
(
@Tables varchar(2000),
@PrimaryKey varchar(500),
@Sort varchar(500) = NULL,
@CurrentPage int = 1,
@PageSize int = 10,
@Fields varchar(2000) = '*',
@Filter varchar(1000) = NULL,
@Group varchar(1000) = NULL
)
AS
IF @Sort IS NULL OR @Sort = ''
SET @Sort = @PrimaryKey
DECLARE @SortTable varchar(1000)
DECLARE @SortName varchar(1000)
DECLARE @strSortColumn varchar(1000)
DECLARE @operator char(2)
DECLARE @type varchar(1000)
DECLARE @prec int
IF CHARINDEX('DESC',@Sort)>0
BEGIN
SET @strSortColumn = REPLACE(@Sort, 'DESC', '')
SET @operator = '<='
END
ELSE
BEGIN
IF CHARINDEX('ASC', @Sort) = 0
SET @strSortColumn = REPLACE(@Sort, 'ASC', '')
SET @operator = '>='
END
IF CHARINDEX('.', @strSortColumn) > 0
BEGIN
SET @SortTable = SUBSTRING(@strSortColumn, 0, CHARINDEX('.',@strSortColumn))
SET @SortName = SUBSTRING(@strSortColumn, CHARINDEX('.',@strSortColumn) + 1, LEN(@strSortColumn))
END
ELSE
BEGIN
SET @SortTable = @Tables
SET @SortName = @strSortColumn
END
SELECT @type=t.name, @prec=c.prec
FROM sysobjects o
JOIN syscolumns c on o.id=c.id
JOIN systypes t on c.xusertype=t.xusertype
WHERE o.name = @SortTable AND c.name = @SortName
IF CHARINDEX('char', @type) > 0
SET @type = @type + '(' + CAST(@prec AS varchar) + ')'
DECLARE @strPageSize varchar(500)
DECLARE @strStartRow varchar(500)
DECLARE @strFilter varchar(1000)
DECLARE @strSimpleFilter varchar(1000)
DECLARE @strGroup varchar(1000)
IF @CurrentPage < 1
SET @CurrentPage = 1
SET @strPageSize = CAST(@PageSize AS varchar(500))
SET @strStartRow = CAST(((@CurrentPage - 1)*@PageSize + 1) AS varchar(500))
IF @Filter IS NOT NULL AND @Filter != ''
BEGIN
SET @strFilter = ' WHERE ' + @Filter + ' '
SET @strSimpleFilter = ' AND ' + @Filter + ' '
END
ELSE
BEGIN
SET @strSimpleFilter = ''
SET @strFilter = ''
END
IF @Group IS NOT NULL AND @Group != ''
SET @strGroup = ' GROUP BY ' + @Group + ' '
ELSE
SET @strGroup = ''
EXEC(
'
DECLARE @SortColumn ' + @type + '
SET ROWCOUNT ' + @strStartRow + '
SELECT @SortColumn=' + @strSortColumn + ' FROM ' + @Tables + @strFilter + ' ' + @strGroup + ' ORDER BY ' + @Sort + '
SET ROWCOUNT ' + @strPageSize + '
SELECT ' + @Fields + ' FROM ' + @Tables + ' WHERE ' + @strSortColumn + @operator + ' @SortColumn ' + @strSimpleFilter + ' ' + @strGroup + ' ORDER BY ' + @Sort + '
'
)

使用该存储过陈，得到数据，将数据绑定到数据控件，提供了一个pageData类 public class PageData
private void ReceiveOrderJLForm_Load(object sender, EventArgs e)
private int dgvBind()
private int pager1_EventPaging(WindowsApp.MyControl.EventPagingArg e)
{
return dgvBind();
} 效果如下

=========== 很多朋友根据原文的方法编写代码后，出现了“不到BindingSource属性”的问题。 该问题的解决方法： 将bindingSource和bindingNavigator的Modifiers属性设置为public即可。
