Breaking Changes from 4.4.2 to 4.5.1

[jennablackwell]

Hello,
I was trying to update the nuget for Xamarin Forms, and found there were a good amount of breaking changes. Looks like a lot of the commands have been removed from "DayView". How can I update this to the latest library?

<xc:DayView
    CurrentMonthCommand="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"
    CurrentMonthCommandParameter="{Binding DateTime}"
    DateTime="{Binding DateTime}"
    IsCurrentMonth="{Binding IsCurrentMonth}"
    IsInvalid="{Binding IsInvalid}"
    IsSelected="{Binding IsSelected}"
                                
    IsToday="{Binding IsToday}"
    SelectedCommand="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"
    SelectedCommandParameter="{Binding DateTime}"
    Style="{StaticResource DefaultDayViewStyle}"
    TodayCommand="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"
    TodayCommandParameter="{Binding DateTime}"/>

The changelog from 4.4.2 to 4.5 can be found here which explains the breaking changes. The sample app also contains the changes.

State-specific properties have been replaced with state-specific styles. This way, you can change any property instead of just the ones I specifically add (BackgroundColor, TextColor, Command, CommandParameter).

Your example should now be:

<xc:DayView
    DateTime="{Binding DateTime}"
    IsCurrentMonth="{Binding IsCurrentMonth}"
    IsInvalid="{Binding IsInvalid}"
    IsSelected="{Binding IsSelected}"
    IsToday="{Binding IsToday}"
    Style="{StaticResource DefaultDayViewStyle}">

    <xc:DayView.CurrentMonthStyle>
        <Style BasedOn="{x:Static Styles:DefaultStyles.DefaultDayViewCurrentMonthStyle}" TargetType="{x:Type xc:DayView}">
            <Setter Property="Command" Value="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"/>
            <Setter Property="CommandParameter" Value="{Binding DateTime}"/>
        </Style>
    </xc:DayView.CurrentMonthStyle>

    <xc:DayView.TodayStyle>
        <Style BasedOn="{x:Static Styles:DefaultStyles.DefaultDayViewTodayStyle}" TargetType="{x:Type xc:DayView}">
            <Setter Property="Command" Value="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"/>
            <Setter Property="CommandParameter" Value="{Binding DateTime}"/>
        </Style>
    </xc:DayView.TodayStyle>

    <xc:DayView.SelectedStyle>
        <Style BasedOn="{x:Static Styles:DefaultStyles.DefaultDayViewSelectedStyle}" TargetType="{x:Type xc:DayView}">
            <Setter Property="Command" Value="{Binding BindingContext.ChangeDateSelectionCommand, Source={x:Reference This}}"/>
            <Setter Property="CommandParameter" Value="{Binding DateTime}"/>
            </Style>
    </xc:DayView.SelectedStyle>
</xc:DayView>

Where the Styles namespace is defined as xmlns:Styles="clr-namespace:XCalendar.Forms.Styles;assembly=XCalendar.Forms" for XCalendar.Forms or
xmlns:Styles="clr-namespace:XCalendar.Maui.Styles;assembly=XCalendar.Maui" for XCalendar.Maui.

It is more verbose but it allows for greater customisation and removes the need to redefine default values to try to match the default style and also allows easier customisation in C# because of the XCalendar.Forms.Styles namespace.
