PatternOccurrenceOfDayInMonth Property (DateRecurrence)

Gets/sets whether the recurrence should occur on the first, second, third, fourth or last occurrence of the day of the week (corresponding to the value of the PatternDaysOfWeek property) in its respective month.
Syntax
'Declaration
 
Public Overridable Property PatternOccurrenceOfDayInMonth As RecurrencePatternOccurrenceOfDayInMonth
public virtual RecurrencePatternOccurrenceOfDayInMonth PatternOccurrenceOfDayInMonth {get; set;}
Example
The following code sample demonstrates how to use the Owner's RecurringDateSettings collection to define different working hours for the first weekday of each month, every other Friday, and every weekday, by defining the working hours on three different recurrent bases:

Imports System.Collections.Generic
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinSchedule
Imports System.Diagnostics

        '  Add a new Owner to the Owners collection
        Dim myOwner As Owner = Me.calendarInfo.Owners.Add("myCalendar")

        '  Create a DateRecurrence object for the first weekday of each month,
        '  beginning on the first day of the current year.
        Dim firstOfMonth As DateRecurrence = New DateRecurrence(New DateTime(DateTime.Today.Year, 1, 1))

        '  Make the recurrence only span the current year.
        firstOfMonth.RangeEndDate = New DateTime(DateTime.Today.Year, 12, 31)

        '  Set the pattern properties for the recurrence.
        firstOfMonth.PatternFrequency = RecurrencePatternFrequency.Monthly
        firstOfMonth.PatternType = RecurrencePatternType.Calculated
        firstOfMonth.PatternOccurrenceOfDayInMonth = RecurrencePatternOccurrenceOfDayInMonth.First
        firstOfMonth.PatternDaysOfWeek = RecurrencePatternDaysOfWeek.AllWeekdays

        '  Create an OwnerRecurringDateSettings object using the new recurrence.
        Dim firstOfMonthSettings As OwnerRecurringDateSettings = New OwnerRecurringDateSettings(firstOfMonth)

        '  Specify the working hours for the first weekday of each month
        '  as 8AM to 4:30PM.
        firstOfMonthSettings.WorkingHours.Add(New TimeRange(TimeSpan.FromHours(8), TimeSpan.FromHours(16.5)))

        '  Now create a DateRecurrence object that will occur on every other Friday
        Dim everyOtherFriday As DateRecurrence = New DateRecurrence(New DateTime(DateTime.Today.Year, 1, 1))

        '  Make the recurrence only span the current year.
        everyOtherFriday.RangeEndDate = New DateTime(DateTime.Today.Year, 12, 31)

        '  Set the pattern properties for the recurrence.
        everyOtherFriday.PatternFrequency = RecurrencePatternFrequency.Weekly
        everyOtherFriday.PatternInterval = 2
        everyOtherFriday.PatternDaysOfWeek = RecurrencePatternDaysOfWeek.Friday

        '  Create an OwnerRecurringDateSettings object using the new recurrence.
        Dim everyOtherFridaySettings As OwnerRecurringDateSettings = New OwnerRecurringDateSettings(everyOtherFriday)

        '  Specify the working hours for every other Friday as 9AM to 3PM.
        everyOtherFridaySettings.WorkingHours.Add(New TimeRange(TimeSpan.FromHours(9), TimeSpan.FromHours(15)))

        '  Now create a DateRecurrence object that will occur every weekday
        Dim everyWeekday As DateRecurrence = New DateRecurrence(New DateTime(DateTime.Today.Year, 1, 1))

        '  Make the recurrence only span the current year.
        everyWeekday.RangeEndDate = New DateTime(DateTime.Today.Year, 12, 31)

        '  Set the pattern properties for the recurrence.
        everyWeekday.PatternFrequency = RecurrencePatternFrequency.Daily
        everyWeekday.PatternDaysOfWeek = RecurrencePatternDaysOfWeek.AllWeekdays

        '  Create an OwnerRecurringDateSettings object using the new recurrence.
        Dim everyWeekdaySettings As OwnerRecurringDateSettings = New OwnerRecurringDateSettings(everyWeekday)

        '  Specify the working hours for every weekday as 9AM to 5:30PM
        everyWeekdaySettings.WorkingHours.Add(New TimeRange(TimeSpan.FromHours(9), TimeSpan.FromHours(17.5)))

        '  Now add each of the three OwnerRecurringDateSettings objects to the Owner's
        '  RecurringDateSettings collection. Note that the order in which they are added
        '  is important; as a rule, the one that generates the fewest occurences should
        '  be added first. This is because when the working hours are defined by the
        '  WorkingHours collection, any range of time that does not appear in the collection
        '  is considered to fall within the non-working hour range, i.e., the resolution
        '  process ends there.
        '
        '  In this example, If we don't add the monthly and weekly recurrences before
        '  the daily one, the daily one will generate occurrences on the first weekday
        '  of every month and every other Friday, superceding the monthly and weekly recurrences.
