Gets or sets the the count of columns to be displayed by a single CalendarView.

Declaration

public int Columns { get; set; }

Property Value

System.Int32

Remarks

If the calendar represents a multi view, this property applies to the child views inside the multi view.

Culture

Gets or sets the CultureInfo supported by this RadCalendar object.

Describes the names of the culture, the writing system, and the calendar used, as well as access to culture-specific objects that provide methods for common operations, such as formatting dates and sorting strings.

Declaration

public CultureInfo Culture { get; set; }

Property Value

System.Globalization.CultureInfo

Remarks

The culture names follow the RFC 1766 standard in the format "<languagecode2>-<country/regioncode2>", where <languagecode2> is a lowercase two-letter code derived from ISO 639-1 and <country/regioncode2> is an uppercase two-letter code derived from ISO 3166. For example, U.S. English is "en-US". In cases where a two-letter language code is not available, the three-letter code derived from ISO 639-2 is used; for example, the three-letter code "div" is used for cultures that use the Dhivehi language. Some culture names have suffixes that specify the script; for example, "-Cyrl" specifies the Cyrillic script, "-Latn" specifies the Latin script.

The following predefined CultureInfo names and identifiers are accepted and used by this class and other classes in the System.Globalization namespace.

CurrentCalendar

Gets the default System.Globalization.Calendar instance as specified by the default culture.

Declaration

public Calendar CurrentCalendar { get; }

Property Value

System.Globalization.Calendar

Remarks

A calendar divides time into measures, such as weeks, months, and years. The number, length, and start of the divisions vary in each calendar.

Any moment in time can be represented as a set of numeric values using a particular calendar. For example, the last vernal equinox occurred at (0.0, 0, 46, 8, 20, 3, 1999) in the Gregorian calendar. An implementation of Calendar can map any DateTime value to a similar set of numeric values, and DateTime can map such sets of numeric values to a textual representation using information from Calendar and DateTimeFormatInfo. The textual representation can be culture-sensitive (for example, "8:46 AM March 20th 1999 AD" for the en-US culture) or culture-insensitive (for example, "1999-03-20T08:46:00" in ISO 8601 format).

A Calendar implementation can define one or more eras. The Calendar class identifies the eras as enumerated integers where the current era (CurrentEra) has the value 0.

In order to make up for the difference between the calendar year and the actual time that the earth rotates around the sun or the actual time that the moon rotates around the earth, a leap year has a different number of days than a standard calendar year. Each Calendar implementation defines leap years differently.

For consistency, the first unit in each interval (for example, the first month) is assigned the value 1.

The System.Globalization namespace includes the following Calendar implementations: GregorianCalendar, HebrewCalendar, HijriCalendar, JapaneseCalendar, JulianCalendar, KoreanCalendar, TaiwanCalendar, and ThaiBuddhistCalendar.

CurrentViewColumn

The column in the multi-view table where the focused date is positioned.

Declaration

public int CurrentViewColumn { get; set; }

Property Value

System.Int32

CurrentViewRow

Gets or sets the row in the multi-view table where the focused date is positioned.

Declaration

public int CurrentViewRow { get; set; }

Property Value

System.Int32

DateRangeSeparator

Gets or sets the separator string that will be put between start and end months in a multi view title.

Declaration

public string DateRangeSeparator { get; set; }

Property Value

System.String

DateTimeFormat

Gets or sets a DateTimeFormatInfo instance that defines the culturally appropriate format of displaying dates and times as specified by the default culture.

Declaration

public DateTimeFormatInfo DateTimeFormat { get; }

Property Value

System.Globalization.DateTimeFormatInfo

Remarks

A DateTimeFormatInfo can be created only for the invariant culture or for specific cultures, not for neutral cultures.

The cultures are generally grouped into three sets: the invariant culture, the neutral cultures, and the specific cultures.

The invariant culture is culture-insensitive. You can specify the invariant culture by name using an empty string ("") or by its culture identifier 0x007F. InvariantCulture retrieves an instance of the invariant culture. It is associated with the English language but not with any country/region. It can be used in almost any method in the Globalization namespace that requires a culture. If a security decision depends on a string comparison or a case-change operation, use the InvariantCulture to ensure that the behavior will be consistent regardless of the culture settings of the system. However, the invariant culture must be used only by processes that require culture-independent results, such as system services; otherwise, it produces results that might be linguistically incorrect or culturally inappropriate.

A neutral culture is a culture that is associated with a language but not with a country/region. A specific culture is a culture that is associated with a language and a country/region. For example, "fr" is a neutral culture and "fr-FR" is a specific culture. Note that "zh-CHS" (Simplified Chinese) and "zh-CHT" (Traditional Chinese) are neutral cultures.

The user might choose to override some of the values associated with the current culture of Windows through Regional and Language Options (or Regional Options or Regional Settings) in Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

If UseUserOverride is true and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, the properties of the NumberFormatInfo instance returned by the NumberFormat property, and the properties of the CompareInfo instance returned by the CompareInfo property. If the user settings are incompatible with the culture associated with the CultureInfo (for example, if the selected calendar is not one of the OptionalCalendars ), the results of the methods and the values of the properties are undefined.

Note: In this version of RadCalendar the NumberFormatInfo instance returned by the NumberFormat property is not taken into account.

Property Value

System.String

Use the SelectedDate property to determine the selected date on the >RadCalendar control.

The SelectedDate property and the SelectedDates collection are closely related. When the AllowMultipleSelect property is set to false, a mode that allows only a single date selection, SelectedDate and SelectedDates[0] have the same value and SelectedDates.Count equals 1. When the AllowMultipleSelect property is set to true, mode that allows multiple date selections, SelectedDate and SelectedDates[0] have the same value.

The SelectedDate property is set using a System.DateTime object.

When the user selects a date on the RadCalendar control, the SelectionChanged event is raised. The SelectedDate property is updated to the selected date. The SelectedDates collection is also updated to contain just this date.

Note Both the SelectedDate property and the SelectedDates collection are updated before the SelectionChanged event is raised. You can override the date selection by using the OnSelectionChanged event handler to manually set the SelectedDate property. The SelectionChanged event does not get raised when this property is programmatically set.

SelectedDates

Gets a collection of DateTime objects that represent the selected dates on the RadCalendar control.

Declaration

public DateTimeCollection SelectedDates { get; }

Property Value

DateTimeCollection

A DateTimeCollection that contains a collection of System.DateTime objects representing the selected dates on the RadCalendar control. The default value is an empty DateTimeCollection.

Remarks

Use the SelectedDates collection to determine the currently selected dates on the control.

The SelectedDate property and the SelectedDates collection are closely related. When the AllowMultipleSelect property is set to false, a mode that allows only a single date selection, SelectedDate and SelectedDates[0] have the same value and SelectedDates.Count equals 1. When the AllowMultipleSelect property is set to true, mode that allows multiple date selections, SelectedDate and SelectedDates[0] have the same value.

The SelectedDates property stores a collection of DateTime objects.

When the user selects a date or date range (for example with the column or rows selectors) on the RadCalendar control, the SelectionChanged event is raised. The selected dates are added to the SelectedDates collection, accumulating with previously selected dates. The range of dates are not sorted by default. The SelectedDate property is also updated to contain the first date in the SelectedDates collection.

You can also use the SelectedDates collection to programmatically select dates on the Calendar control. Use the Add, Remove, Clear, and SelectRange methods to programmatically manipulate the selected dates in the SelectedDates collection.

Note Both the SelectedDate property and the SelectedDates collection are updated before the SelectionChanged event is raised.You can override the dates selection by using the OnSelectionChanged event handler to manually set the SelectedDates collection. The SelectionChanged event is not raised when this collection is programmatically set.
