gridview没有数据的行，怎么把它隐藏或者删除

求下代码例子

sql读出来的时候加为空的判断揪心过了，你的空记录是指第一列没有数据吗？

 select * from xxx where 第一列的列名称>''

如果无法修改sql，数据源改为DataView，可以使用RowFilter过滤

        System.Data.DataTable dt;
        //取数据填充dt的代码
        System.Data.DataView dv = dt.DefaultView;
        dv.RowFilter = "不能为空的列名称>''";

最好在数据源查询处就控制住，把不符合的数据过滤掉

为什么要这样拼接？这样的数据可以用一个JSON 搞一下 弄成一个对象封装好 就应该可以很容易解决你的问题了吧

gridview 也是基于 MVC设计的，你只能通过数据源进行控制，没有其它办法；
