如何禁用项目上的鼠标项目时ListBox中的颜色​​更改？

Question

我有一些简单的ListBox对象。 当鼠标在某个对象上时，对象背景颜色发生变化。

是否有可能避免这种颜色变化与禁用对象？ （此对象包含必须启用的按钮）

感谢您的任何帮助。

您可以从ListBoxItem模板中删除视觉状态动画。 默认模板可以找到here。

没有鼠标悬停背景的风格看起来如此：

<Style x:Key="IgnoreMouseOverItem" TargetType="ListBoxItem"> 
    <Setter Property="Padding" Value="3" /> 
    <Setter Property="HorizontalContentAlignment" Value="Left" /> 
    <Setter Property="VerticalContentAlignment" Value="Top" /> 
    <Setter Property="Background" Value="Transparent" /> 
    <Setter Property="BorderThickness" Value="1"/> 
    <Setter Property="TabNavigation" Value="Local" /> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="ListBoxItem"> 
       <Grid Background="{TemplateBinding Background}"> 
        <vsm:VisualStateManager.VisualStateGroups> 
         <vsm:VisualStateGroup x:Name="CommonStates"> 
          <vsm:VisualState x:Name="Normal" /> 
          <vsm:VisualState x:Name="MouseOver"> 
           <!--<Storyboard> 
            <DoubleAnimation Storyboard.TargetName="fillColor" Storyboard.TargetProperty="Opacity" Duration="0" To=".35"/> 
           </Storyboard>--> 
          </vsm:VisualState> 
          <vsm:VisualState x:Name="Disabled"> 
           <Storyboard> 
            <DoubleAnimation Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="Opacity" Duration="0" To=".55" /> 
           </Storyboard> 
          </vsm:VisualState> 
         </vsm:VisualStateGroup> 
         <vsm:VisualStateGroup x:Name="SelectionStates"> 
          <vsm:VisualState x:Name="Unselected" /> 
          <vsm:VisualState x:Name="Selected"> 
           <Storyboard> 
            <DoubleAnimation Storyboard.TargetName="fillColor2" Storyboard.TargetProperty="Opacity" Duration="0" To=".75"/> 
           </Storyboard> 
          </vsm:VisualState> 
         </vsm:VisualStateGroup> 
         <vsm:VisualStateGroup x:Name="FocusStates"> 
          <vsm:VisualState x:Name="Focused"> 
           <Storyboard> 
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Visibility" Duration="0"> 
             <DiscreteObjectKeyFrame KeyTime="0"> 
              <DiscreteObjectKeyFrame.Value> 
               <Visibility>Visible</Visibility> 
              </DiscreteObjectKeyFrame.Value> 
             </DiscreteObjectKeyFrame> 
            </ObjectAnimationUsingKeyFrames> 
           </Storyboard> 
          </vsm:VisualState> 
          <vsm:VisualState x:Name="Unfocused"/> 
         </vsm:VisualStateGroup> 
        </vsm:VisualStateManager.VisualStateGroups> 
        <Rectangle x:Name="fillColor" Opacity="0" Fill="#FFBADDE9" IsHitTestVisible="False" RadiusX="1" RadiusY="1"/> 
        <Rectangle x:Name="fillColor2" Opacity="0" Fill="#FFBADDE9" IsHitTestVisible="False" RadiusX="1" RadiusY="1"/> 
        <ContentPresenter 
          x:Name="contentPresenter" 
          Content="{TemplateBinding Content}" 
          ContentTemplate="{TemplateBinding ContentTemplate}" 
          HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
          Margin="{TemplateBinding Padding}"/> 
        <Rectangle x:Name="FocusVisualElement" Stroke="#FF6DBDD1" StrokeThickness="1" Visibility="Collapsed" RadiusX="1" RadiusY="1" /> 
       </Grid> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

，然后应用新样式到ListBox

<ListBox ItemContainerStyle="{StaticResource IgnoreMouseOverItem}" />

如果你只是想避免突出显示，你可以使用ItemsControl的。
