C#分页插件Webdiyer

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

Repeater没有自带的分页功能，搜罗了一下发现AspNetPager.dll这个插件比较好用拿出来分享一下，老鸟勿喷

先来一张效果图

该插件的好处在这里就不多说了，直接上代码

(1)首先需要把AspNetPager.dll引用到项目中来

(2)Aspx代码

ASPX代码

(4)涉及到的存储过程

涉及到的分页存储过程 
ALTER  procedure [dbo].[GetPage]
    @tblName      varchar(1000),       -- 表名(必要参数)
    @Fields      varchar(1000)='*',      --要返回的列，要保证没有名称的列有别名
    @PageSize     int = 25,           -- 页尺寸
    @PageIndex    int = 1,            -- 页码
    @OrderType    varchar(50) = '',    -- 设置排序类型,不要加order by 
    @strWhere     varchar(2000) = ''  -- 查询条件 (注意: 不要加 where)
as 
BEGIN
    declare @Mycount varchar(2000)---此变量存储SQL语句，用于获得符合条件的记录总数
    declare @strSql varchar(2000)----此变量存储SQL语句，用于获得符合条件的记录
    if @OrderType=''
    set @OrderType='getdate()'

    if(@strWhere='')
    begin
        set @Mycount='select count(*) from '+@tblName
        set @strsql='select * from (select top ('+cast(@PageSize*@PageIndex as varchar(10))+') ROW_NUMBER()over(order by '+@OrderType+') rowNumber,'+@Fields+' from '+@tblName+')  t where rowNumber>'+cast((@PageIndex-1)*@PageSize as varchar(10))
    end
    else
    begin
        set @Mycount='select count(*) from '+@tblName+' where '+@strWhere
        set @strsql='select * from (select top ('+cast(@PageSize*@PageIndex as varchar(10))+') ROW_NUMBER()over(order by '+@OrderType+') rowNumber,'+@Fields+' from '+@tblName+' where '+@strWhere+')  t where rowNumber>'+cast((@PageIndex-1)*@PageSize as varchar(10))
    end  
        exec(@strSql)
        exec(@Mycount)
END

 

到此一个基本的分页功能就完成了
