WeekRule Property

Returns or sets the rule used to determine the first week of the year.
Syntax
'Declaration
 
Public Property WeekRule As Nullable(Of CalendarWeekRule)
public Nullable<CalendarWeekRule> WeekRule {get; set;}
Remarks

By default the System.Globalization.DateTimeFormatInfo.CalendarWeekRule of the Culture associated with the control's System.Windows.FrameworkElement.Language is used to determine the week numbers for dates displayed within the control. The WeekRule is used when calculating the CalendarItemArea.WeekNumbers.

Example
The following sample demonstrates some of the properties that can be used to override the culture settings.

Imports Infragistics.Windows.Editors
Imports Infragistics.Windows.Controls

    Private Sub InitializeCalendar(ByVal calendar As XamMonthCalendar)
        ' by default the week numbers are not displayed
        calendar.WeekNumberVisibility = Visibility.Visible

        ' by default the WeekRule is null and the week rule
        ' used is based on that of the culture (as specified 
        ' by the FrameworkElement.Language property) but the 
        ' WeekRule property can be used to override that 
        ' setting
        calendar.WeekRule = Globalization.CalendarWeekRule.FirstFullWeek

        ' similarly the FirstDayOfWeek is null and is based on 
        ' the information in the culture
        calendar.FirstDayOfWeek = DayOfWeek.Monday
    End Sub
using Infragistics.Windows.Editors;
using Infragistics.Windows.Controls;
using System.Globalization;

        private void InitializeCalendar(XamMonthCalendar calendar)
        {
            // by default the week numbers are not displayed
            calendar.WeekNumberVisibility = Visibility.Visible;

            // by default the WeekRule is null and the week rule
            // used is based on that of the culture (as specified 
            // by the FrameworkElement.Language property) but the 
            // WeekRule property can be used to override that 
            // setting
            calendar.WeekRule = CalendarWeekRule.FirstFullWeek;

            // similarly the FirstDayOfWeek is null and is based on 
            // the information in the culture
            calendar.FirstDayOfWeek = DayOfWeek.Monday;
        }
