好的，我将用图像讨论我的问题，以便我们轻松解决。希望。

首先，下图显示了 PersonalInfo.aspx 下的 PersonalInfo gridview 在此处输入图像描述

二、下图是MobileINfo.aspx下的MobileInfo gridview在此处输入图像描述

三、现在我们要编辑这个页面MobileInfo.aspx中的记录在此处输入图像描述

第四，下图我认为一切正常，因为数据已经更新。但...在此处输入图像描述

第五次也是最后一次，我回到 PersonalInfo.aspx 但它给了我这个...数据已被删除在此处输入图像描述

这是我的 PersonalInfo.aspx 代码

我希望有人可以在这里帮助我。谢谢。

我在这里看到的是您UpdateCommand在两个页面上具有相同的内容，但是在您进行更新的第二个页面上，这些值全部为空或不存在，结果是您实际上删除了它们。

继续页面的此 UpdateCommandMobileINfo.aspx并删除您实际上不使用的字段 - 仅保留您实际更改它们的字段 - 或者将其余部分引用到不存在的数据，因此它们被删除。

UpdateCommand="UPDATE [DriversRecords] SET [Username] = ?, [Password] = ?, [FirstName] = ?, [LastName] = ?, [MiddleName] = ?, [Address] = ?, [Age] = ?, [Gender] = ?, [ContactNumber] = ?, [PlateNumber] = ?, [Color] = ?, [Brand] = ?, [LiscensedNumber] = ?, [SSSNumber] = ?, [TIN] = ?, [Type] = ?, [Model] = ?, [BirthDay] = ?, [BirthMonth] = ?, [BirthYear] = ? WHERE [ID] = ?"

例如，在第二页LiscensedNumber退出，但Gender不是。更新后，性别将更新为 null 或空字符串。
