Wpf system.windows.datepicker更改标题背景色

我一直在尝试更改wpf默认日期选择器的背景色。现在它是深蓝色的黑色文本，客户希望它变为白色。我已经编写了很多代码，但似乎什么都不起作用

请帮忙。谢谢

 <Style x:Key="DateStyle" TargetType="{x:Type DatePcker}" BasedOn="{x:Null}">
    <Style.Triggers>
        <Trigger Property="IsFocused" Value="True">
            <Setter Property="Background" Value="Yellow" />
        </Trigger>
        <Trigger Property="IsReadOnly" Value="True">
            <Setter Property="Background" Value="White" />
        </Trigger>
    </Style.Triggers>
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="CharacterCasing" Value="Upper"/>
    <Setter Property="FontFamily" Value="Segoe UI" />
    <Setter Property="FontSize" Value="11" />
</Style>

这是我的约会选择者

 <DatePicker Grid.Column="2" Grid.ColumnSpan="2" Grid.Row="4" Height="25" HorizontalAlignment="Left" TabIndex="3" 
                                                        Name="dpFillingDateFrom" VerticalAlignment="Center" Width="97" Text="12/12/2011" SelectedDateFormat="Short"/>

就这么过去吧。 更改wpf的默认日期选择器的背景色并非易事，但您可以按照以下步骤操作

1日期选择器具有日历属性，因此覆盖日历默认控件模板

2在日历控制模板中，有一个CalendarItemStyle，您可以在其中覆盖CalendarItemStyle defaulttemplate。在这里，您可以自定义背景颜色以及标题按钮

<Style x:Key="ItemStyle" TargetType="primitives:CalendarItem">
                <Setter Property="Template">
                    <Setter.Value>

            <ControlTemplate TargetType="primitives:CalendarItem">
                <ControlTemplate.Resources>
                    <DataTemplate x:Key="DayTitleTemplate">
                        <TextBlock Text="{Binding}"
                                           HorizontalAlignment="Center" />
                    </DataTemplate>
                </ControlTemplate.Resources>

                <DockPanel Name="PART_Root" 
                                   LastChildFill="True">
                    <Button x:Name="PART_PreviousButton" 
                                    DockPanel.Dock="Left"
                                    Content="&lt;"
                                    Focusable="False" />

                    <Button x:Name="PART_NextButton" 
                                    DockPanel.Dock="Right"
                                    Content="&gt;" 
                                    Focusable="False" />

                    <Button x:Name="PART_HeaderButton"                                             
                                    DockPanel.Dock="Top"
                                    FontWeight="Bold"
                                    Focusable="False" />

这可能是重复的工作cal的外观改变了，但我不能只改变标题。我只想改变标题的颜色。我不知道如何使用xaml，我试着进行实验，最终得到了一个奇怪的cal。请注意，我没有ToolKit，我现在可以更改标题，但现在我无法更改所选日期的高亮度颜色。请问选择的日期在哪个属性/标签下？
