推荐答案

这里有一些可能的事情.

首先:当您说完美保存"时，您怎么知道?你怎么检查的?您是否检查过它，或者只是假设它已正确保存，因为它似乎没有出现错误，并且没有提出此内容已更改，您要保存更改?"?消息框?

其次:您是如何保存数据的?

第三:您如何确定要从与保存到的数据库相同的数据库中加载数据?加载数据时是否使用任何过滤器?

我?我打赌第一个-您没有检查，也没有保存.但是如果没有相关的代码片段，我不确定...

There are a couple of possible things here.

Firstly: when you say "it save perfectly" how do you know? How did you check? Did you check, or just assume it was saved correctly because it did not appear to error, and did not come up with a "this has been changed, do you want to save changes?" message box?

Secondly: How did you save your data?

Thirdly: How sure are you that you are loading data from the same database as you are saving to? Do you use any filters when you load the data?

Me? I''m betting on the first one - you didn''t check, and it didn''t get saved. But without relevant code fragments, I can''t be sure...
