Ical/ics file

aiden · Post by **aiden** » Mon Mar 18, 2024 9:53 pm

I manage an activities website where people can reserve activities. After making a reservation, customers receive a confirmation email containing the appointment date and time, along with other relevant details. How can I add in ASP.NET an .ics file as a link in the email so that when a customer clicks on it, they are immediately redirected to their calendar to add the appointment?

Use the Email_Sending server event.

I have the email functions in the row_inserted and moved the codes from there to Email_sending and then the mail function didn't work anymore in the email_sending I can't receive/send emails. Do you have a solution for this?

Show your codes.

You can also open your project with Visual Studio and add a break point there to debug your codes.

Now emailing works in the email-sending server event and I have also been able to add the ical file, but when someone clicks on the file, they are redirected to their calendar and the appointment information is not displayed + the file is only displayed in Outlook, not in Gmail.

public virtual bool EmailSending(EmailBase email, dynamic? args) {
//Common - Email_Sending - Reserveren;
//Belangrijk om ook de Email Notifications aan te zetten in de settings bij Tables;
if (CurrentPageID() == "add") { // If Add page
email.Sender = "aiden2@gmail.com";
email.Recipient = ExecuteScalar("SELECT ReserverenEmailadres FROM Reserveren WHERE ReserverenId='" + ReserverenId.CurrentValue + "'").ToString();
email.Cc = "";
email.Bcc = "";
email.Subject = " bevestiging van je reservering";
email.Content = ""; // Voeg extra inhoud toe
email.Format = "html";
email.Charset = "utf-8";

    // Haal de benodigde informatie uit de database
    string reserverenNaam = ExecuteScalar("SELECT ReserverenNaam FROM Reserveren WHERE Reserveren.ReserverenId = '" + ReserverenId.CurrentValue + "'").ToString().ToLower(); // eerste letter naar hoofdletter converteren
    reserverenNaam = char.ToUpper(reserverenNaam[0]) + reserverenNaam.Substring(1); // eerste letter hoofdletter maken

Try passing your content directly to the AddAttachment method:

email.AddAttachment(tempFilePath, icsContent);

Succeeded, thank you very much! When someone makes a reservation, they receive double confirmation emails instead of one. Do you know why that happens? I actually want one confirmation email to go to the customer after making the reservation and one to me.

public virtual bool EmailSending(EmailBase email, dynamic? args) {
//Common - Email_Sending - Reserveren;
//Belangrijk om ook de Email Notifications aan te zetten in de settings bij Tables;

        email.Recipient = "info@aiden.nl";
        email.Cc = "";
        email.Bcc = "";

        //en dan 1 nieuwe mail naar de persoon die de reservering maakt verstuurd wordt:
        email.Recipient = ExecuteScalar("SELECT ReserverenEmailadres FROM Reserveren WHERE ReserverenId='" + ReserverenId.CurrentValue + "'").ToString();
        email.Cc = "";
