Silverlight WP7 工具包，DatePicker\TimePicker 字体大小问题

Question

我对来自 Silverlight Toolkit for WP7 的 TimePicker\DatePicker 有以下问题。我不知道如何在选择器内的 TextBox 中更改字体大小:



字体大小属性:

<toolkit:DatePicker FontSize="30" Foreground="Black"  Header="tas" Name="dpiker"/>

仅更改标题字体大小



虽然 字体家族 或 字重 适用于 Header 和 TextBox。如何更改文本框中的字体大小？

这是因为在它们的默认样式中，字体大小不是通过 TemplateBinding 设置的。看到 ** 部分，这应该可以解决问题。 :)

    <Style TargetType="toolkit:DatePicker">
        <Setter Property="Background" Value="{StaticResource PhoneTextBoxBrush}"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneTextBoxForegroundBrush}"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="PickerPageUri" Value="/Microsoft.Phone.Controls.Toolkit;component/DateTimePickers/DatePickerPage.xaml"/>
        <Setter Property="ValueStringFormat" Value="{}{0:d}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="toolkit:DatePicker">
                    <StackPanel>
                        <ContentControl ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" Foreground="{StaticResource PhoneSubtleBrush}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="12,0,12,-4"/>
                        <Button x:Name="DateTimeButton" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Content="{TemplateBinding ValueString}" Foreground="{TemplateBinding Foreground}" FontFamily="{TemplateBinding FontFamily}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Height="72" **FontSize="{TemplateBinding FontSize}"**/>
                    </StackPanel>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
