推荐答案

这里的问题是，您必须在网格视图中使用插入.不要插入用户编辑内容并更新现有值.当您插入一个单独的条目在Db中.我还以为主键要么不存在，要么可能不是笔和数量以外的其他列.

The problem here is that you must be using the insert into grid-view. Don''t do insert user edit and update the existing value. when you insert a separate entry is made in the Db. I am laso thinking that the primary key is either non existent or perhaps some other column than pen and quantity.
