Class RadCalendar
Represents a selection control that allows you to select dates from a calendar.
Inheritance
Namespace: Telerik.Windows.Controls
Assembly: Telerik.Windows.Controls.Input.dll
Syntax
[TelerikToolboxCategory("Input")]
public class RadCalendar : Control, IThemable
Remarks
The Calendar control allows the user to select a single date.
The user can navigate in the Calendar by clicking the arrow buttons in the calendar header that would cycle through the list of days, months or years. Clicking in-between the two arrows would change the DisplayMode of the calendar so that it displays a year if a month was displayed (The same applies for. Clicking the button with today's date would navigate to the month view of the current month.
The SelectionMode allows more than one date to be selected. There are three modes of selection - SelectionMode.Single, SelectionMode.Multiple and SelectionMode.Extended. Advanced keyboard selection - dragging while holding Ctrl or/and Shift is supported. The SelectedDates property is a list of all selected dates.
The DisplayMode property allows you to get or set the current display mode. By handling the DisplayModeChanged routed event you would receive a notification whenever a change in the display mode occurs.
Disabling or enabling the selection of dates can be controlled by the SelectableDateStart and SelectableDateEnd properties. If none of the latter two has been set, i.e. their value is null then all the calendar dates are selectable.
The SelectedDate property holds the DateTime value of the selected date. The default value is null (no date is selected). Adding a handler for the SelectedDate event would enable you to be notified whenever a date is selected.
Similarly, to modify which dates the user can navigate to, use the DisplayDateStart and DisplayDateEnd properties. Setting the DisplayDate property navigates the calendar to the month or year that contain this date (depending on the current DisplayMode). Please note that the DisplayDate property cannot be set to null.
The Calendar has more than 20 properties which allow you to set styles, style selectors, templates and template selectors for the different views and buttons of the Calendar. The Calendar help articles provide more information on the control parts and template structures.
Please note that the RadCalendar currently supports only Gregorian calendar.

DisplayDate
Gets or sets the current date to display. This is a dependency property.
Declaration
public DateTime DisplayDate { get; set; }
Property Value
System.DateTime
|
Remarks
The DisplayDate property specifies the date to display in the RadCalendar. If no display date was set, then the SelectedDate is used. Alternatively, if no date is selected then DateTime.Today is used.
Setting the display date does not affect the DisplayMode of the Calendar, e.g. if the DisplayMode is set to Year changing the DisplayDate within the same year would not change the view, while setting a DisplayDate of a different year would change the view.
Similarly to the other date properties of the Calendar, the time part of the DateTime object is not only ignored but set to 00:00:00 as well. See SelectedDate for an example and more information on that behavior.
The DisplayDateStart and DisplayDateEnd properties defined a range within which the DisplayDate can be set, i.e. a range within which the user can navigate. If you try to set a DisplayDate outside the defined range an ArgumentOutOfRangeException would be thrown. Similarly, setting a display range that excludes the current DisplayDate would throw an exception.
Changing the DisplayDate property fires the DisplayDateChanged event. Please note that unless the DisplayDate is changed from code the event would fire only when the displayed month or year actually changes, i.e. selecting a day within the currently viewed month would not fire the event (or change the property). Selecting a month while the DisplayMode is Year would fire the event if the month is different from the previously selected.
Please note that unlike the other date properties DisplayDate cannot be set to null.

DisplayDateEnd
Gets or sets the last date that would be able to be displayed. This is a dependency property.
Declaration
public Nullable<DateTime> DisplayDateEnd { get; set; }
Property Value
System.Nullable<System.DateTime>
|
Remarks
The DisplayDateEnd property can limit the dates which can be navigated to. The DisplayDateEnd is the date furthest away in time that can be displayed. Setting the property to null would enable all dates to be viewed.
Please note that ArgumentOutOfRange exception would be thrown if the DisplayDateEnd is set to a date earlier than the currently displayed date (DisplayDate).
More information about setting the displayable dates' range and an example can be found on the DisplayDateStart help page.
See Also
DisplayDateStart
Gets or sets the first date that would be able to be displayed. This is a dependency property.
Declaration
public Nullable<DateTime> DisplayDateStart { get; set; }
Property Value
System.Nullable<System.DateTime>
|
Remarks
The DisplayDateStart property together with DisplayDateEnd allows you to define a range within which the user would be able to navigate. The DisplayDateStart does not affect whether a date can be selected or not. Please refer to SelectableDateStart for more information on controlling selection.
For example setting the DisplayDateStart to DateTime.Today would ensure that the Calendar would not be able to navigate to the previous month or year but changing the DisplayMode or selecting dates from the current month is unaffected.
Similarly to the other date properties of the Calendar, the time part of the DateTime object is not only ignored but set to 00:00:00 as well (coerced). See SelectedDate for an example and more information on that behavior.
Setting the DisplayDateStart to null means that DateTime.MinValue would be the start of the displayable range. The default values is null.
See Also
DisplayMode
Gets or sets the display mode of the Calendar. This is a dependency property.
Declaration
public DisplayMode DisplayMode { get; set; }
Property Value
DisplayMode
|
Remarks
The DisplayMode property controls the span of time the calendar is currently displaying: month, year, decade and century.
The display mode can be changed by clicking the calendar header between the previous and next buttons and by choosing from the list of months/years/decades. Alternatively the DisplayMode can be changed programmatically although this is not recommended since this may contradict user expectations.
The DisplayModeChanged event is fired when the property changes. The CalendarModeChangedEventArgs provide the old and new value of the display mode. An example where the event is used can be found on the SelectedDate help page.

FirstDayOfWeek
Gets or sets the day that is considered the beginning of the week.
Declaration
public Nullable<DayOfWeek> FirstDayOfWeek { get; set; }
Property Value
System.Nullable<System.DayOfWeek>
|
Remarks
The FirstDayOfWeek property specifies which is the day in the leftmost column of the calendar view, i.e. which is the first day of the week.
If the property is set to null, the Culture will be checked, if a specific culture is set, its FirstDayOfWeek is considered. Otherwise the CurrentCulture will be used.
Generally, the start of the week varies with different cultures so if you would like the Calendar to display the dates as you see them, be sure to set the FirstDayOfWeek property or the Culture property.
calendar.FirstDayOfWeek = CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek;

Remarks
The SelectedDate property identifies the last date that has been selected. If more than one date needs to be selected, please see the SelectedDates property.
Setting the SelectedDate property to null would deselect any selection. The default value is null.
Selecting a date fires the SelectedDate event. An example about handling events is provided below.
Please note that the user would not be able to select dates outside the SelectableDates range defined by the SelectableDateStart and SelectableDateEnd properties.
Note that all DateTime properties of the RadCalendar discard the time of the DateTime object, i.e. the time is coerced to 0:0:0.
SelectedDates
Gets an list of the currently selected dates.
Declaration
public IList<DateTime> SelectedDates { get; }
Property Value
System.Collections.Generic.IList<System.DateTime>
|
Remarks
The SelectedDates collection is an observable collection (although it is exposed as an IList) which contains the currently selected dates and can be used in binding.
In Single SelectionMode the collection would still be populated with the selected date (if any).
Just as with SelectedDate, all the dates in the collection will be coerced and should be between the SelectableDateStart/End and DisplayDateStart/End.
SelectionMode
Gets or sets the types of selection that would be allowed in the Calendar. This is a dependency property.
Declaration
public SelectionMode SelectionMode { get; set; }
Property Value
SelectionMode
|
Remarks
The Selection mode in the Calendar works very much like the SelectionMode in a ListBox.
Selection across several months is possible, either by navigating to a different month and selecting dates there or by displaying more than one months at a time (See Rows and Columns properties).
The default value is Single.
UseShortestDayNames
Gets or sets UseShortestDayNames property. This is a dependency property.
Declaration
public bool UseShortestDayNames { get; set; }
Property Value

ViewsHeaderVisibility
Gets or sets the visibility of the header of the calendar views (month, year, decade, century). This is a dependency property.
Declaration
public Visibility ViewsHeaderVisibility { get; set; }
Property Value
System.Windows.Visibility
|
Remarks
When multi-view calendar is used (the Rows and Columns properties have been set) showing the CalendarViews headers helps the specific views to be identified. For example if 4 months are visible, headers would appear on top of each month and not just the calendar header.
The default value is Collapsed.
YearButtonStyle
Gets or sets the style for the year buttons in the decade views of the calendar. This is a dependency property.
Declaration
public Style YearButtonStyle { get; set; }
Property Value
System.Windows.Style
|
Remarks

|
Remarks
The YearViewHeaderFormat is a DateTime format which will be used for the header of the YearView.
If the property is set to null, a default format "yyyy" will be used.
YearViewPanel

Declaration
public ItemsPanelTemplate YearViewPanel { get; set; }
Property Value
System.Windows.Controls.ItemsPanelTemplate
