कैसे रंग बदलने की तारीख के लिए छुट्टियों

Question 1

मैं करना चाहते हैं पर प्रकाश डाला छुट्टियों में से एक । लेकिन पता नहीं कैसे रंग बदलने के कैलेंडर आइटम. मैं स्थापित करने की कोशिश की शैली के लिए CalendarDayButton

<Window x:Class="WorkingCalendar.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WorkingCalendar"
    mc:Ignorable="d"
    Title="MainWindow" 
    Height="450" 
    Width="600">
<Window.Resources>
    <local:HolidayDaysConverter x:Key="HolidayDaysConverter"/>

    <Style x:Key="calendarDayButtonStyle" TargetType="{x:Type CalendarDayButton}">
        <Setter Property="TextElement.Foreground" Value="Green"/>
        <Setter Property="TextElement.FontSize" Value="20"/>
        
        <!--<Style.Triggers>
            <DataTrigger Binding="{Binding Converter={StaticResource HolidayDaysConverter}}" Value="True">
                <Setter Property="Background" Value="Red"/>
            </DataTrigger>
        </Style.Triggers>-->
    </Style>
</Window.Resources>
    
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>

    <Viewbox>
        <Calendar SelectionMode="MultipleRange"
                  MinHeight="100"
                  MinWidth="100"
                  CalendarDayButtonStyle="{StaticResource calendarDayButtonStyle}">
            
            
        </Calendar>
    </Viewbox>
    
</Grid>

मैं बदल सकते हैं fontsize, लेकिन FiregroundColor परिवर्तन नहीं करता है. क्यों? और कैसे परिवर्तन अग्रभूमि?

Question 2

क्यों?

क्योंकि Foreground करने के लिए hardcoded है #FFBADDE9 डिफ़ॉल्ट टेम्पलेट है ।

और कैसे परिवर्तन अग्रभूमि?

बनाने के अपने स्वयं के कस्टम टेम्पलेट को कॉपी करके एक डिफ़ॉल्ट में अपने XAML मार्कअप और उसके मूल्य को बदलने Foreground संपत्ति. अपने Style तो इस तरह दिखेगा:

<Style x:Key="calendarDayButtonStyle" TargetType="{x:Type CalendarDayButton}">
    <Setter Property="TextElement.Foreground" Value="Green"/>
    <Setter Property="TextElement.FontSize" Value="20"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type CalendarDayButton}">
                <Grid>
                    <VisualStateManager.VisualStateGroups>
