【转】分页控件ASPNETPAGET

最近开发项目的时候用到了分页控件ASPNETPAGET，现在将使用心得记录在此
1添加存储过程





--第二个存储过程
/*
***************************************************************
**  千万数量级分页存储过程  **
***************************************************************
参数说明:
1.Tables             :表名称,视图
2.PrimaryKey         :主关键字
3.Sort               :排序语句，不带Order By 比如：NewsID Desc,OrderRows Asc
4.CurrentPage        :当前页码
5.PageSize           :分页尺寸
6.Filter             :过滤语句，不带Where
7.Group             :Group语句,不带Group By
