C＃WPF Xaml：将视图中的所有文本全局设置为一种颜色，将所有背景设置为另一种颜色

Question

Is there a way (using data binding or simply xaml) to set the background of all elements in a view to one color, and all text to another?

I know I can edit each element in the view one by one, but I I'd like to see if this is possible with settings at a global level. Kind of like how everything by default is set to black on white.

I guess what I'm asking is if there is a feature/setting of a WPF application that offers what I'm looking for, and/or what I should search to find an answer online.

My project isn't using anything but what visual studio offers when you create a WPF project, so I can't use a prism or mvvm light approach.

Thanks in advance for your answer!

Answer 1

Globally...or simply XAML... if there is a feature/setting of a WPF application that offers what I'm looking for

In Application Resource add style like this:

<Style TargetType="Control">
  <Setter Property="Background" Value ="Blue"/>
  <Setter Property="Foreground" Value ="Red"/>
</Style>
<Style TargetType="TextBlock">
  <Setter Property="Background" Value ="Blue"/>
  <Setter Property="Foreground" Value ="Red"/>
</Style>

Based on your target element you want to set background.

When you say "the background of all elements in a view" you should be more specific, If by 'element' you mean UIElement then there is no Background property in UIElement . If it means Control then not all UIElements derive from Control (eg TextBlock) and finally if it means every UIElement derived type defined in your view that have a Background property, then you should add different styles for each type without setting the x:key to the YourView.Resources like this:

<Window.Resources>
    <Style TargetType="{x:Type TextBox}">
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="Blue" />
    </Style>
    <Style TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Red" />
        <Setter Property="Foreground" Value="Blue" />
    </Style>
    ...
</Window.Resources>

使用控件集合，通过它可以控制WPF中的所有控件
