我在这里看到了很多与这个问题非常接近的问题,但没有一个似乎适合这个特定的场景。
描述:我在主页面中有带有登录按钮的 ID 和密码字段。这些在“LoginValidationGroup”中并且工作正常。
现在,在 Default.aspx 中,我有一个电子邮件文本框和提交按钮,它们位于“NotifyMeValidation”组中,它们也可以工作,但如果你按下回车键而不是提交按钮,它们就不行了。提交按钮工作正常 - 输入键......不是那么多。
Enter 键会导致在 LoginValidationGroup 上进行验证,即使 TextBox 设置为 CausesValidation="true",并且它位于 NotifyMeValidation 组中。
我保证人们会在该框中输入电子邮件并按 Enter。我会!!!当他们这样做时,他们会在顶部看到一个标注气球,告诉他们需要用户 ID。
我的错误是什么?如果我需要发布实际代码,我可以这样做。
实际上,让我继续做吧。
