后台代码：
protected string pcount=string.Empty; //总条数 protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { pcount = SQLHelper.GetDataSet("select count(*) from K_SysModuleNode").Rows[0][0].ToString(); } }
Ajax处理程序：

分页存储过程：
ALTER PROC [dbo].[proc_Pager] @NewPageIndex int,--当前页码 @PageSize int,--分页条数 @order varchar(64), @strSql nvarchar(max) --sql语句 as DECLARE @str varchar(8000) BEGIN SET @str = 'SELECT COUNT(1) FROM ('+@strSql+')T' SET @str = @str+' SELECT * FROM (SELECT row_number() over(order by '+@order+') as Rownum,* FROM('+@strSql+')T1)T ' END SET @str=@str+' where Rownum between '+cast((@NewPageIndex-1)*@PageSize+1 as varchar(20))+' and '+cast(@NewPageIndex*@PageSize as varchar(20)) --IF LEN(@order)<>0 --SET @str=@str+' order by '+@order EXEC(@str)
