推荐答案

据我所知，行业标准"是显示带有必填字段的"*". > 控件中是否填充了某些内容不会更改该字段为必填项的事实.

删除"*"的事实可能使用户认为该字段不再是必填字段，因此删除了输入的数据.

我的建议是遵守此标准"，并始终在必填字段旁边显示"*".使用验证器给出有关在字段中输入的数据的错误.

As I understand it the "industry standard" is to show a ''*'' with mandatory fields.
Whether something is filled in the control does not change the fact that the field is mandatory.

The fact that the ''*'' is removed might make the user think the field is no longer mandatory and remove the data entered.

My advise would be to adhere to this "standard" and always show the ''*'' next to mandatory fields. Use the validator to give an error about the data entered in the field.
