Data Model for the Recurrence Table
The Recurrence table describes the recurrence pattern applied to a WebSchedule Activity, which has been set-up to periodically recur. All columns correspond with .NET properties having the same name on a Recurrence object, unless otherwise noted.
The Recurrence table is new in the WebSchedule Data Model for Ultimate UI for ASP.NET 2006 Volume 2 and later.
| Column Name |

Null Allowed? |
Remarks |
|
|
|
Primary Key . A numeric value uniquely identifying this Recurrence.
|
|
|
|
Date with Midnight time (and adjusted for UTC) on which Recurrence pattern expires.
May be 12/31/9999 to represent a Recurrence that is supposed to go on forever.
|
|
|
|
Specifies which day or days of the week an Activity falls on as a binary bit mask.
For more information, see the Flags enumeration "RecurrencePatternDaysOfWeek."
|
|
|
|
This is the timezone offset from UTC of the last person to create or modify this Recurrence. It is measured as a (signed) number of seconds.
The offset is used to clarify other explicit values when this recurrence is seen by users in other time zones.
|
|
|
|
When DayOfMonth > 0 it represents a date in the calendar month, and is stored in the DayOfMonth property of the Recurrence object.
When DayOfMonth < 0 it represents an ordinal occurrence within the month as follows:
-1 - RecurrenceDayOfMonth.First
-2 - RecurrenceDayOfMonth.Second
-3 - RecurrenceDayOfMonth.Third
-4 - RecurrenceDayOfMonth.Fourth
-5 - RecurrenceDayOfMonth.Last
When used in this way, the value is stored in the RecurrenceDayOfMonth property of the Recurrence.
RecurrenceDayOfMonth may be combined with a DayOfWeekMask value to represent a recurrence pattern such as "Third Wednesday of the Month."
|
|
|

Specifies the calendar month of the year as a number from 1 to 12.
This column only applies when Period is 'Y' (Yearly). When not applicable, it should have the value 0.

|
Specifies the most appropriate Period for use as an interval between occurrences.

0 - Prompt user for their choice (default).
1 - User always edits the series.
