How to add RecurrenceDay to the mask in a loop

[Greg]

I'm looking for a way to add to the RecurrenceDay mask dynamically. I see that the Silverlight and WPF have AddDay functionality but I'm not having any luck finding it for the ASP.NET AJAX implementation.

My goal is to loop through multiple weekdays defined in a database and add them to the WeeklyRecurrenceRule DayOfWeekMask when creating a new appointment in the RadScheduler.

Thanks!

Hello,

I would suggest reviewing the following help article that shows how you can work with the recurrence rule of specific appointment. For example you may implement your custom logic in the RadScheduler FormCreated server-side event handler. 

Kind regards,

Thank you for the response, I have reviewed all of the documentation I could find including the link you posted. I'm sure my solution is unique so I'll post the working code below. The scenario I was up against was a start date and time, end date and time and the need to loop through the days of the week to populate the mask used in building the recurrance rule.  This solution could be tooled to use a delimited string of days during the week also. (e.g. 1,3,5,7 for Mon, Wed, Fri, Sun). I hope my solution or parts of it can help anybody looking for this flexibility.

    bool errors = false;

    // BUILD THE APPOINTMENT FOR THE SCHEDULE SEGMENT

    {

        // UNLESS THE START AND END SPANS MIDNIGHT - which is handled below

        string appointmentStart = String.Format("{0:MM/dd/yyyy}", Convert.ToDateTime(dr["scheduleSegmentStartDate"]));

I have found an oddity in the appointment.Description = appointmentDescription; line... The database field gets populated with NULL.

I have a workaround by using appointment.Attributes["scheduleDescription"] = appointmentDescription.

The question is why doesn't the appointment.Description property work?

I'm using Telerik.Web.UI, v.2013.1.417.40 (Dev)

Thanks,
Greg

Hello,

Indeed the description field in the data base is not properly updated when RadScheduler InsertAppointment method is used for inserting an appointment. We would need a bit more time to investigate that issue and I will post any update here as soon as possible.

here is what I came up with

Dim range As RecurrenceRange = New RecurrenceRange()
range.EventDuration = EndTime.Subtract(StartTime)
range.Start = StartTime
range.RecursUntil = CDate(dr("RecurEndDate")).Add(difference)
  'range.MaxOccurrences = 1000
Dim recDay As Integer = 0
 Select Case (dr("Period")) 'guessing the correct day that matches these masks
      Case "1000000" : recDay = RecurrenceDay.Sunday
      Case "0100000" : recDay = RecurrenceDay.Monday
      Case "0010000" : recDay = RecurrenceDay.Tuesday
      Case "0001000" : recDay = RecurrenceDay.Wednesday
     Case "0000100" : recDay = RecurrenceDay.Thursday
Case "0000010" : recDay = RecurrenceDay.Friday
 Case "0000001" : recDay = RecurrenceDay.Saturday
     Case "1111111" : recDay = RecurrenceDay.EveryDay
     Case "1000001" : recDay = RecurrenceDay.WeekendDays
     Case "0111110" : recDay = RecurrenceDay.WeekDays
      Case Else
          Dim mask As String = dr("Period")
          If mask.Substring(0, 1) = "1" Then recDay = recDay Or RecurrenceDay.Sunday
          If mask.Substring(1, 1) = "1" Then recDay = recDay Or RecurrenceDay.Monday
          If mask.Substring(2, 1) = "1" Then recDay = recDay Or RecurrenceDay.Tuesday
          If mask.Substring(3, 1) = "1" Then recDay = recDay Or RecurrenceDay.Wednesday
          If mask.Substring(4, 1) = "1" Then recDay = recDay Or RecurrenceDay.Thursday
          If mask.Substring(5, 1) = "1" Then recDay = recDay Or RecurrenceDay.Friday
          If mask.Substring(6, 1) = "1" Then recDay = recDay Or RecurrenceDay.Saturday

End Select
 Dim rule As WeeklyRecurrenceRule = New WeeklyRecurrenceRule(dr("Every"), recDay, range)
If arExceptions.Count > 0 Then
       For Each item As String In arExceptions
        rule.Exceptions.Add(CDate(item).Add(range.Start.TimeOfDay().Add(excDiffernce)))
        Next
       End If

apt.RecurrenceRule = rule.ToString()
