推荐答案

据我从问题描述中所得到的，只有在文本字段中输入任何内容，您才希望验证器起作用.但据我所知，您无法使用标准必填字段验证器来满足条件.当您单击表单上的某些内容时，它将验证关联控件的字段.您可以使用所需的如果"条件在.NET中尝试CustomValidator.

As far as I can get from your problem description that you would like your validator to work only if you have entered anything in the text field. But as far I know you cannot have conditions with the standard required field validator. It will validate for the field of the associated control aoon as you click something on the form. You may try CustomValidator in .NET with the required "if" conditions you would like to have.
