WPF：如何調整禁用文本框的樣式？

Question

如果我想更改所有禁用文本框的背景顏色 - 使其更明顯，它們被禁用 - 我將如何做到這一點？我想特別將它們改爲深灰色，但關於DISABLED輸入的樣式的答案通常很好。

Answer 1

如果你想有一個快速的解決方案，而無需重新模板的整個控制： -

<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> 

Answer 2

沒有顯示禁用顏色的樣式屬性 - 所以您將不得不修改default ControlTemplate。要更改背景顏色，它看起來像你應該能夠只是複製粘貼，修改一個刷：

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

---

編輯通過「複製 - 粘貼」，我的意思是，你必須整體風格複製粘貼到你的資源：

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


<Color x:Key="WindowColor">#FFE8EDF9</Color> 
<Color x:Key="ContentAreaColorLight">#FFC5CBF9</Color> 
<Color x:Key="ContentAreaColorDark">#FF7381F9</Color> 

<Color x:Key="DisabledControlDarkColor">#FFC5CBF9</Color> 
<Color x:Key="DisabledForegroundColor">#FF888888</Color> 

<Color x:Key="SelectedBackgroundColor">#FFC5CBF9</Color> 
<Color x:Key="SelectedUnfocusedColor">#FFDDDDDD</Color> 

<Color x:Key="ControlLightColor">White</Color> 
<Color x:Key="ControlMediumColor">#FF7381F9</Color> 
<Color x:Key="ControlDarkColor">#FF211AA9</Color> 

<Color x:Key="ControlMouseOverColor">#FF3843C4</Color> 
<Color x:Key="ControlPressedColor">#FF211AA9</Color> 


<Color x:Key="GlyphColor">#FF444444</Color> 
<Color x:Key="GlyphMouseOver">sc#1, 0.004391443, 0.002428215, 0.242281124</Color> 

<!--Border colors--> 
<Color x:Key="BorderLightColor">#FFCCCCCC</Color> 
<Color x:Key="BorderMediumColor">#FF888888</Color> 
<Color x:Key="BorderDarkColor">#FF444444</Color> 

<Color x:Key="PressedBorderLightColor">#FF888888</Color> 
<Color x:Key="PressedBorderDarkColor">#FF444444</Color> 

<Color x:Key="DisabledBorderLightColor">#FFAAAAAA</Color> 
<Color x:Key="DisabledBorderDarkColor">#FF888888</Color> 

<Color x:Key="DefaultBorderBrushDarkColor">Black</Color> 

<!--Control-specific resources.--> 
<Color x:Key="HeaderTopColor">#FFC5CBF9</Color> 
<Color x:Key="DatagridCurrentCellBorderColor">Black</Color> 
<Color x:Key="SliderTrackDarkColor">#FFC5CBF9</Color> 

<Color x:Key="NavButtonFrameColor">#FF3843C4</Color>
