Basic Usage

.NET

Install the NuGet package

• https://www.nuget.org/packages/XCalendar.Core

Now you can use the Calendar

public Calendar MyCalendar { get; set; } = new Calendar();

Xamarin Forms

Install the NuGet package

• https://www.nuget.org/packages/XCalendar.Forms

Create a Calendar in your ViewModel

public Calendar MyCalendar { get; set; } = new Calendar();

Add the following xmlns to your page or view

xmlns:xc="clr-namespace:XCalendar.Forms.Views;assembly=XCalendar.Forms"

Bind to the properties of your Calendar

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage
    x:Class="App1.MainPage"
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:xc="clr-namespace:XCalendar.Forms.Views;assembly=XCalendar.Forms">
    
        <xc:CalendarView

Alternatively, these properties can be set directly from code-behind without the use of MVVM.

Navigation Overview

Calendar

Navigation can be performed by setting the NavigatedDate property of the Calendar.

Alternatively, navigation can be performed using the Navigate method; it takes a parameter specifying the TimeSpan to navigate by. The Calendar can handle exceptions caused by non-representable dates such as DateTime.MaxValue.AddDays(1).

Variable time units such as months can be obtained by using the'AddMonths' method on a DateTime and subtracting the result from the current date. The 'TryAdd' and 'TrySubtract' methods in DateTimeExtensions are useful if you ever plan to navigate to the bounds of the DateTime struct.

Limiting

Navigation can be limited to a specific range of dates by changing the NavigationLowerBound and NavigationUpperBound properties of the Calendar.

Looping

You can specify the behaviour of the CalendarView when trying to navigate outside the bounds defined by NavigationLowerBound and NavigationUpperBound by changing the NavigationLoopMode property.

CalendarView

The CalendarView does not have navigation built into it by default. Instead, it exposes the BackwardsArrowCommand, BackwardsArrowCommandParameter, ForwardsArrowCommand, and ForwardsArrowCommandParameter which can be used to implement this functionality.

The CalendarView displays its navigation bar using a NavigationView. Its appearance can be changed using the NavigationViewTemplate property of the CalendarView.

Displaying Dates Overview

Calendar

Start of the Week

You can specify what day of the week should be considered as the start by setting the StartOfWeek property of the Calendar.

For Example:

• When StartOfWeek is DayOfWeek.Monday, the first row of February 2022 would be 1st Feb - 7th Feb.
• When StartOfWeek is DayOfWeek.Wednesday, the first row of February 2022 would be 26th Jan - 1st Feb
• When StartOfWeek is DayOfWeek.Sunday, the first row of February 2022 would be 31st Jan - 6th Feb

Rows

You can set how many rows you want to display by changing the Rows property of the Calendar.

Alternatively, the Calendar can automatically set the Rows value to the minimum amount needed to display every week of the NavigatedDate's month. This can be done by setting the AutoRows property of the Calendar to true. You can ensure that AutoRows always uses the highest Rows value required in the year by setting the AutoRowsIsConsistent property of the Calendar to true.

For example, when the start of the week is Monday, these are the values that will be calculated using AutoRows:

Date	Value	Value (AutoRowsIsConsistent)
January 2021	5	6
February 2021	4	6
March 2021	5	6
April 2021	5	6
May 2021	6	6
June 2021	5	6
July 2021	5	6
August 2021	6	6
September 2021	5	6
Ocotober 2021	5	6
November 2021	5	6
December 2021	5	6

Day Of Week Order

The displayed dates are stored in the DayNamesOrder property.

The value of the DayNamesOrder is automatically calculated by the Calendar based on the values of its StartOfWeek and CustomDayNamesOrder:

• First, the Calendar determines the default order of the days of the week using the value of the StartOfWeek property of the Calendar.
• Then, the Calendar creates a default list of dates based on the days of week in the calculated order.
• If the CustomDayNamesOrder property of the Calendar is null, these default dates will be shown.
• If the CustomDayNamesOrder property of the Calendar is not null, the Calendar will cherry-pick values from these default dates, mapping their DayOfWeek to the values specified in the CustomDayNamesOrder property and shows the result.

The CustomDayNamesOrder property supports duplicates and non-chronological orders, but must contain at least one value.

Page Start Mode

You can set the date that the page starts on relative to the NavigatedDate by setting the PageStartMode property of the Calendar.

For Example:

• If Rows is set to 1, PageStartMode.FirstDayOfMonth would only ever display the first week of the NavigatedDate's month.
• If Rows is set to 6, PageStartMode.FirstDayOfYear would only ever display the first 6 weeks of the NavigatedDate's year.

Events/Appointments

To add events to the calendar use the calendar's events property. The calendar will add indicators on days that are within the start date and end date of an event. The position and shape of the indicators can be modified by using various properties and templates of a DayView inside the DayTemplate property of the CalendarView.

Localisation

The calendar uses CultureInfo.CurrentCulture for its logic. For example if StartOfWeek has not been set, it will default to CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek.

CalendarView

The bare minimum needed to get the CalendarView working is to set the NavigatedDate, DayNamesOrder, and Days properties of the CalendarView.

Customising days

A day can be customised by setting the CalendarView's DayTemplate property.

If using a DayView, the essential properties you need to set to replicate existing functionality are the IsSelected, IsToday, IsCurrentMonth, and IsInvalid properties. You can view more info on how these states work as well as all the properties in the DayView at the DayView Properties wiki page.

Customising the days container

The container for days can be customised by setting the CalendarView's DaysViewTemplate property.

Customising the days of the week

To customise the look of each day of the week, the DayNameTemplate property of the CalendarView can be used. It is a DataTemplate with a BindingContext of DayOfWeek.

To change the TextColor for example you would put a Label in a DataTemplate and change the Label's TextColor property.

Customising the days of week container

There is also the DayNamesTemplate which lets you modify the container for the days of the week. This is a ControlTemplate.

Localisation

To change the displayed days of the week, change CultureInfo.CurrentUICulture.
To change the displayed month names, change CultureInfo.CurrentCulture.

Best to do this before InitializeComponent() in App.xaml.cs. In the future I may add a culture property to Calendar or CalendarView so that you don't have to set the culture for the entire application.

Date Selection Overview

Calendar

Selection can be performed by changing/modifying the SelectedDates collection.

Alternatively, selection can be performed by calling the ChangeDateSelection method.

Selection can also be performed by setting the RangeSelectionStart and RangeSelectionEnd properties to non-null values. If they are both not null, CommitRangeSelection will be called and they will be set back to null. This mimicks what the ChangeDateSelection method does when the Calendar's SelectionType property is set to SelectionType.Range.

The way in which dates are selected can be changed by setting the Calendar's SelectionType property.

The action taken when calling the ChangeDateSelection or CommitRangeSelection methods can be changed by setting the SelectionAction property.

Different combinations of the SelectionType and SelectionAction result in different behaviours when calling the ChangeDateSelection method.

For example:

• SelectionType.Single + SelectionAction.Replace will achieve traditional single selection.
• SelectionType.Single + SelectionAction.Modify will achieve traditional multiple selection.
• SelectionType.Range + SelectionAction.Replace will achieve traditional range selection.

Additionally, the calendar's SelectionDirection property can be used to control what order dates must be selected in.

For example:

• SelectionType.Range + SelectionAction.Replace + SelectionDirection.StartToEnd will cause the range selection to only be changed by selecting the earlier, then later date.
• SelectionType.Range + SelectionAction.Replace + SelectionDirection.EndToStart will cause the range selection to only be changed by selecting the later, then earlier date.
• SelectionType.Single + SelectionAction.Modify + SelectionDirection.Confined will cause the selected date to require being in between the earliest and latest selected dates.

CalendarView

The CalendarView does not implement selection by default. The easiest way to implement this is to set the CalendarView's DayTemplate to a DayView and set its CurrentMonthCommand, TodayComand, and SelectedCommand to a command that will select the underlying ICalendarDay's date.

To make it easier to replicate default behaviour of calendar days, there is a default style for each state of the DayView in the XCalendar.[Forms/Maui].Styles.DefaultStyles namespace which can be used via a namespace reference in XAML and the {x:Static } markup extension. These styles can also be inherited from to easily customise the look and behaviour of a day in a specific state.

Tips

Reference	Tip
Displaying Dates	A general rule to follow is that your PageStartMode should always be smaller than or equal to the time unit the calendar is navigating.
Displaying Dates	If the amount of rows does not initialise correctly, try setting the AutoRows property before the Rows property.
None	When setting the value of DayNameTemplate, in some cases, the DataTemplate's x:DataType property needs to be set in order for Converters or DataTriggers to work.
Sample App	When copying code from the sample app, watch out for copy-paste errors. Common issues: Copied code references a style defined in the sample app but not your app. Copied code references something in the ViewModel that isn't present in your app's ViewModel. Copied code relies on nuget packages installed in the sample app which aren't present in your app.

NavigationLoopMode.LoopMinimum: Loop to the upper bound when navigating past the lower bound. NavigationLoopMode.LoopMaximum: Loop to the lower bound when navigating past the upper bound. NavigationLoopMode.LoopMiniumAndMaximum: Loop as defined in both LoopMinimum and LoopMaximum.
SelectionType	SelectionType	Defines how the ChangeDateSelection method processes the selected date. SelectionType.None: Nothing happens. SelectionType.Single: The SelectionAction is performed on the date. SelectionType.Range: Sets the calendar's RangeSelectionStart property to the date if it's null, otherwise sets the calendar's RangeSelectionEnd property if it isn't null, otherwise performs the SelectionAction on the dates between RangeSelectionStart and RangeSelectionEnd inclusive.
SelectionAction	SelectionAction	Defines what happens when a date is selected via the ChangeDateSelection or CommitRangeSelection methods. SelectionAction.Add: The dates will be added to the selection if not already present. SelectionAction.Remove: The dates will be removed from the selection if present. SelectionAction.Modify: Performs both SelectionAction.Add and SelectionAction.Remove on the selection. SelectionAction.Replace: Will replace the current selection with the dates if they are not the same.
SelectionDirection	SelectionDirection	Defines where the newly selected date must be in relation to the earliest and latest selected dates when changing the date selection via the ChangeDateSelection method. If it isn't in the correct place, nothing happens. SelectionDirection.StartToEnd: The newly selected date must be later than or equal to the earliest selected date. SelectionDirection.EndToStart: The newly selected date must be earlier than or equal to the latest selected date. SelectionDirection.Confined: The newly selected date must be in between or equal to the earliest and latest selected date. SelectionDirection.ConfinedReverse: The newly selected date must be outside or equal to the earliest selected date and latest selected date.
RangeSelectionStart	DateTime?	The start of the range of dates to perform selection on inclusive. If RangeSelectionStart and RangeSelectionEnd are not null, CommitRangeSelection will be called and their values will be set back to null.
RangeSelectionEnd	DateTime?	The end of the range of dates to perform selection on inclusive. If RangeSelectionStart and RangeSelectionEnd are not null, CommitRangeSelection will be called and their values will be set back to null.
Rows	int	The number of rows to display. Each row represents one week.
AutoRows	bool	Whether the calendar should automatically determine the minimum number of Rowsneeded to display the month or not.
AutoRowsIsConsistent	bool	Determines if the AutoRows property should display the same number of rows throughout each month in the year.
StartOfWeek	DayOfWeek	The day of the week that will be considered as the start of the week.
DayNamesOrder	ObservableRangeCollection<DayOfWeek>	The order that the days of the week are currently displayed in. If CustomDayNamesOrder is not null, this value is set to it.
CustomDayNamesOrder	ObservableRangeCollection<DayOfWeek>	When this value is not null, DayNamesOrder is set to this.
PageStartMode	PageStartMode	How the calendar will use the NavigatedDate to generate the first date in the page (and therefore the subsequent sequence of dates). PageStartMode.FirstDayOfWeek Use the first date in NavigatedDate's Week. PageStartMode.FirstDayOfMonth Use the first date in the first week of NavigatedDate's Month. PageStartMode.FirstDayOfYear Use the first date in the first week of NavigatedDate's Year.
Days	ObservableRangeCollection<T>	The days currently being displayed by the calendar. Note: Displayed days != displayed dates. For example if DayNamesOrder is "Monday, Monday, Monday Tuesday" and the row is displaying the week of 10th January 2022 - 16th January 2022, there would be 4 days displayed but only 2 dates displayed: 10th January 2022 and 11th January 2022.
Days	ObservableRangeCollection<TEvent> where TEvent : IEvent	The events/appointments of the calendar. The default class and interface for events have 4 properties: Title (string) Description (string) Start Date (DateTime) EndDate(DateTime?) The event will be passed to any ICalendarDay's Events property when their DateTime falls between the StartDate and EndDate. If EndDate is null, any day after the StartDate will have that event.

Events

Event	Description
DateSelectionChanged	This is raised when the SelectedDates collection is changed or modified. It uses the DateSelectionChangedEventArgs class to provide the PreviousSelection and CurrentSelection properties. Note: DateSelectionChanged will still be called if the collection contains the same elements but in a different order. Having duplicates may also cause unexpected behaviour.
DaysUpdating	Raised at the start of the 'UpdateDays' method.
DaysUpdated	Raised at the end of the 'UpdateDays' method.
