Текст метки не обновляется при нажатии кнопки ОТПРАВИТЬ - ASP.NET

Question

У меня есть страница контактов, на которой я отправляю письмо при нажатии кнопки ОТПРАВИТЬ, все работает нормально, но кнопка не была отключена в конце кода, а текст метки не обновлялся для отражения изменений. Я полностью уверен, какая метка не обновляется, так как код выполняется нормально.

Это главная страница:

Эта дочерняя страница

Это C# код сервера

protected void Button1_Click(object sender, EventArgs e)
    {
        String[] ParamToPass = new String[9];
        String ConnectionString = "DESKTOP-9V04GKP";
        try
        {
        ParamToPass[0] = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
        ParamToPass[1] = SenderName.Text;
        ParamToPass[2] = SenderSurname.Text;
        ParamToPass[3] = SenderTitle.Text;
        ParamToPass[4] = SenderCompany.Text;
        ParamToPass[5] = SenderEmail.Text;
        ParamToPass[6] = SenderTelephone.Text;
        ParamToPass[7] = SenderSubject.Text;
        ParamToPass[8] = TxtComments.Text;

            //MailAddress to = new MailAddress("mail1");
            //MailAddress from = new MailAddress("mail2");

            //MailMessage message = new MailMessage(from, to);
            //message.Subject = SenderSubject.Text.ToString();
            //message.Body = TxtComments.Text.ToString();

            //SmtpClient client = new SmtpClient("smtp.gmail.com", 587)
            //{
            //    Credentials = new NetworkCredential("credentials go here"),
            //    EnableSsl = true

            //};
            //// code in brackets above needed if authentication required


            //client.Send(message);

            Label1.Text = "Thank you for your message we will get back at you as soon as possible";
            Button1.Enabled = false;
            SQL_Insert(ConnectionString, ParamToPass); 
        }
        catch (SmtpException ex)
        {
            Label1.Text = "We are experiencing technical difficulty please come back at another time";
            Button1.Enabled = true;
        }
        
    }

Answer 1

Поскольку все кнопки asp. net имеют тип «отправить», то после нажатия кнопки страница обновляется и генерирует PostBack.

У вас есть два варианта решения этой проблемы.

Вариант 1 - «preventDefault ()» на вашей кнопке:

$("#Button1").click(function (e) {    
 e.preventDefault();
}

Вы можете добавить e.preventDefault(); к существующей функции ClientSideClick, которую вы не включили в свой вопрос , поэтому я не могу изменить ваш текущий код.

Вариант 2 - изменить OnClientClick с:

<asp:Button ID="Button1" runat="server" OnClientClick="ClientSideClick(this)" Text="SEND" Width="78px" OnClick="Button1_Click"/>

Кому:

<asp:Button ID="Button1" runat="server" OnClientClick="ClientSideClick(this); return false;" Text="SEND" Width="78px" OnClick="Button1_Click"/>
