我有一个样式应用于我在资源字典中定义的所有文本框.
<Style TargetType="TextBlock">
<Setter Property="TextBlock.FontSize" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontSize, Mode=OneWay}" />
<Setter Property="TextBlock.TextWrapping" Value="Wrap" />
<Setter Property="TextBlock.VerticalAlignment" Value="Center"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="TextBox.FontFamily" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontName, Mode=OneWay}"/>
</Style>\

fontsize和fontstyle属性绑定到实现iNotifyPropertyChanged的特殊用户设置类,它允许更改字体大小和fontfamily以在我的应用程序中立即传播.
但是,在我创建的UserControl中(具有讽刺意味的是,允许用户自定义字体设置的屏幕),我希望字体大小和fontfamily保持静态.无论我尝试什么,我的全局字体设置都会覆盖我在用户控件中设置的内容:
<UserControl x:Class="ctlUserSettings"

<Setter Property="FontSize" Value="14"/>
<Setter Property="FontFamily" Value="Tahoma"/>
</Style.Setters>

我尝试将Style设置为{x:Null},设置内联自定义字体大小,并在此控件的资源中设置样式.没有优先于我的资源字典中的样式. …
