/ 25 апреля 2020

Я пытаюсь проверить, существует ли электронное письмо в базе данных или нет, но каким-то образом событие, похоже, не срабатывает вообще. Я хочу, чтобы, когда кто-то вводил идентификатор электронной почты в текстовое поле и когда он выходил, фокусировал событие servervalidate. должен активировать и подтвердить введенный адрес электронной почты

код Aspx (идентификатор персонализированного идентификатора = "cv3")

Хорошо,

Вам нужно изменить несколько вещей здесь,

Добавить AutoPostBack="true" в текстовое поле vendor_email

Добавить OnTextChanged="vendor_email_TextChanged" в текстовое поле vendor_email 

<asp:TextBox ID="vendor_email" TextMode="Email" CssClass="form-control" 
    OnTextChanged="vendor_email_TextChanged"
    AutoPostBack="true" CausesValidation="true"
    placeholder="e.g. me@mymail.com" required="true" runat="server"></asp:TextBox>

Реализация обработчика событий в коде и вызов Validate () (Read this ) 

protected void vendor_email_TextChanged(object sender, EventArgs e)
{
    Page.Validate();
}

И, наконец,

Изменение имя вашей кнопки отправки на что-то другое, потому что она перезаписывает метод submit () формы 

<asp:Button ID="submit2" runat="server" Text="Submit" Width="81px" OnClick="submit_Click" CausesValidation="true" />
