Question

我正在尝试使用create user向导创建用户。对于电子邮件验证，我使用regualr表达式控制。我将ControlToValidate属性赋予电子邮件文本框的ID。当我提供错误的电子邮件ID并点击创建用户时，它会显示我在<asp:RegularExpressionValidator>中配置的错误消息，但它将进入下一步并说用户已成功创建。电子邮件格式错误时如何停止注册用户。我正在尝试像这样修改CreatingUser事件

protected void CreateUserWizard1_CreatingUser(object sender, LoginCancelEventArgs e)
        {
            bool allfieldsstatus = false;
            RegularExpressionValidator emailvalidator = (RegularExpressionValidator)CreateUserWizardStep1.ContentTemplateContainer.FindControl("emailvalidator");

            if (!emailvalidator.Visible)
            {
                allfieldsstatus = true;
            }

            if (allfieldsstatus)
            {
                e.Cancel = false;
            }
            else
            {
                e.Cancel = true;
            }
        }

但这不起作用。可见性属性根本没有显示。我在if条件下以另一种方式尝试过 if(!emailvalidator.ErrorMessage.length!=0) { allfieldstatus = true; } 这也行不通。因为ErrorMessage属性总是在<asp:RegularExpressionValidator >的配置中存在解决方案是什么？

Answer 1

通常，您应该检查验证是否通过单个验证器控件的IsValid属性或Page本身传递：

if (!emailvalidator.IsValid) {
    e.Cancel = true;
}

或

if (!Page.IsValid) {
    e.Cancel = true;
}

对于向导，您可以在NextButtonClick和FinishButtonClick事件处理程序中执行此检查。

如果您认为这是RegExp问题，请尝试以下方法：

/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i

即使我使用正则表达式验证器，用户也会在电子邮件格式错误时创建
