Question

如果我想更改所有禁用文本框的背景颜色 - 让它们更明显地被禁用 - 我该怎么做？我想特别将它们改为深灰色，但是关于DISABLED输入样式的答案一般都没问题。

Answer 1

如果您想要快速解决方案而无需重新模板化整个控件： -

<Style TargetType="TextBox">
  <Style.Triggers>
    <Trigger Property="IsEnabled" Value="false">
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="TextBox">
            <Border Background="LightGray" BorderBrush="Gray" BorderThickness="1">
              <TextBlock Text="{TemplateBinding Text}" Padding="2" />
            </Border>
          </ControlTemplate>
        </Setter.Value>
      </Setter>
    </Trigger>
  </Style.Triggers>
</Style>

没有为禁用的颜色公开样式属性 - 因此您必须修改default ControlTemplate。要更改背景颜色，看起来您应该只能复制粘贴，并修改一个画笔：

<Color x:Key="DisabledControlLightColor">#FFE8EDF9</Color>

通过“复制粘贴”

编辑，我的意思是您必须将整个样式复制粘贴到您的资源中：

<!--Control colors.-->
<Color x:Key="DisabledControlLightColor">Pink</Color> <!-- #FFE8EDF9-->


<Color x:Key="WindowColor">#FFE8EDF9</Color>
