如果你没有 DataKey ，然后你需要将密钥存储在Row内某处的 HiddenField 或 BoundField 或其他什么。



然后在 GridView.RowUpdating事件 [ ^ ]，找到该字段并检索该值。之后使用键或 Id 对您的数据库运行查询。

If you don't have DataKey, then you need to store the Key somewhere inside the Row either in a HiddenField or BoundField or something.

Then inside GridView.RowUpdating Event[^], find that field and retrieve the value. After that run a Query on your Database using that Key or Id.
