How to find an instance of a recursive meeting on a future date

[Pascal Desmet]

Hi there,

I've created a single meeting for a specific day and a recursive meeting occurring on that same day as well but starting earlier and all works fine. When I try to find all meetings on that specific day (1 fixed and 1 instance of the recurring meeting), I only get the fixed meeting. Only when I ask for the meetings on the same day the recurring meeting started, then I receive both fixed and an instance of the recurring meeting.

In attachment an application to show how I approached the Scheduler control. Can you show me how to get an occurrence of the recurring meeting on a later date than the one used to create it.

Thanks for your help,
Pascal Desmet

Hi Pascal,

#Regarding How to find an instance of a recursive meeting on a future date

You can achieve your requirement by using the GetDateTimeOccurrences from the SchedulerRecurrenceManager in the SfScheduler. The GetDateTimeOccurrences method is used to get the date-time collection at which the recurrence appointment will occur. We have updated the sample and please find the attached sample for the same.

Code snippets:

private void ShowInfo()

{

    var meetingsOnInfoDate = new ObservableCollection<Meeting>();

    var startDate = CurrentDate;

    var endDate = CurrentDate;

    foreach (Meeting app in Meetings)

    {

        if (app.RecurrenceRule != null)

        {

            IEnumerable<DateTime> dateCollection = SchedulerRecurrenceManager.GetDateTimeOccurrences(app.RecurrenceRule, app.From);

            if (dateCollection.Any(d => d.Date == startDate.Date))

            {

                meetingsOnInfoDate.Add(app);

            }

        }

        else if (app.From.Date == CurrentDate)

        {

            meetingsOnInfoDate.Add(app);

        }

    }

    if (meetingsOnInfoDate == null)

    {

        InfoText = "No meetings on this date";

    }

    else

    {

        InfoText = $"Meetings on this date: {CurrentDate.ToString("dd/MM/yyyy")}";

        foreach (var meeting in meetingsOnInfoDate)

        {

            InfoText += "\n" + meeting.EventName;

        }

    }

}

Please find the output for the same,

We hope this helps. Kindly revert us if you have any concerns.

Hi Muniappan and fellow Syncfusion users,

As addendum, I could have found the answer in the documentation if I had read it more in detail at this page:
Appointments in .NET MAUI Scheduler control | Syncfusion

How to get the recurrence dates from RRULE?

The GetDateTimeOccurrences method of .NET MAUI Scheduler retrieves the occurrences date-time list from the RRULE.

• MainPage.xaml.cs

var dateTime = DateTime.Today.AddHours(10);
var recurrenceRule = "FREQ=DAILY;INTERVAL=1;COUNT=3";
var dateCollection = SchedulerRecurrenceManager.GetDateTimeOccurrences(recurrenceRule, dateTime);

/// The following occurrence dates can be retrieved from the given RRULE:
var date1 = 12/14/2021 10:00:00 AM;
var date2 = 12/15/2021 10:00:00 AM;
var date3 = 12/16/2021 10:00:00 AM;

kind regards,
