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

Question

我在使用 Silverlight Toolkit for WP7 中的 TimePicker \ DatePicker 时遇到以下问题。我不知道如何更改选择器内 TextBox 中的字体大小：

FontSize 属性：

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

仅更改标题字体大小

虽然 FontFamily 或 FontWeight 适用于 Header 和文本框。如何更改TextBox中的字体大小？

这是同样的问题o silverlight 论坛

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。请参阅 ** 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>

基于 noxo 的 wordpress 链接，这对我来说效果很好：

    <Style x:Key="DatePickerStyle1" TargetType="toolkit:DatePicker" BasedOn="{StaticResource DateTimePickerStyles}">
        <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="Auto" FontSize="{TemplateBinding FontSize}"/>
                    </StackPanel>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
