推荐答案

我在这里看到的是，你有相同的更新命令上的两个页面，但在第二您所做的更新页面，值都为空或不存在，其结果是，你实际上删除它们。

What I see here is that you have the same UpdateCommand on the two pages, but on the second page that you make the update, the values are all null or not exist and the result is that you actually deletes them.

走在这条更新命令页面 MobileINfo.aspx 并删除你不实际使用领域 - 只保留一个你真正改变他们 - 或者休息被吹罚到不存在的，有前他们删除数据。

Go on this UpdateCommand of the page MobileINfo.aspx and remove the field that you do not actually use - keep only the one that you actually change them - or the rest are refereed to data that not exist and there fore they are delete.

更新命令=UPDATE [DriversRecords] SET [用户名] = [密码] = [名字] = [姓氏] = [中间名] = [地址] =？，[年龄] = [两性] =？[ContactNumber] =？[PlateNumber] =？[颜色] =？[品牌] =？[LiscensedNumber] =？[SSSNumber] =？ [TIN] = [类型] = [产品型号] =？[生日] =？[BirthMonth] =？[BirthYear] =？WHERE [ID] =？

例如，第二页上的 LiscensedNumber 退出，但性别不是。你更新后的性别将更新为空或空字符串。

Eg, on the second page the LiscensedNumber exit, but the Gender not. After your update the Gender will update to null, or empty string.
