推荐答案

RequiredFieldValidator 用于验证必填字段。因此，对于所有强制性字段，您必须放置 RequiredFieldValidator 。



RegualrExpressionValidator 用于检查输入。您可以使用正则表达式仅接受有效输入，并避免检查输入服务器端。对于需要某些特定类型输入的所有控件，例如仅限数字或字母数字，您将不得不使用它。



现在，如果任何控制是强制性的并且需要特定输入类型你必须使用两者。详情请参阅：

RequiredFieldValidator is to validate the mandatory fields. So for all the fields that are mandatory you will have to put a RequiredFieldValidator.

RegualrExpressionValidator is for checking the input. you can use regular expression to accept only valid inputs and save yourself from checking the inputs serverside. For all the controls that need some specific type of input like number only or alphanumeric only you will have to use this.

Now if any control is mandatory and need specific input type you will have to use both. Refer this for details:
