WPF DataGrid的風格

Question

我有以下樣式

<Style x:Key="DataGridRowStyle1" TargetType="{x:Type DataGridRow}"> 
    <Setter Property="Foreground" Value="#FFB3B3B3"/> 
    <Setter Property="Height" Value="25"/> 
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/> 
    <Setter Property="Template" Value="{DynamicResource DataGridRowControlTemplate1}"/> 
    <Style.Triggers> 
     <Trigger Property="IsSelected" Value="True"> 
      <Setter Property="Background" Value="#FF262626"/> 
     </Trigger> 
     <Trigger Property="ItemsControl.AlternationIndex" Value="0"> 
      <Setter Property="Background" Value="#FF383838"/> 
     </Trigger> 
     <Trigger Property="ItemsControl.AlternationIndex" Value="1"> 
      <Setter Property="Background" Value="#FF333333"/> 
     </Trigger> 
    </Style.Triggers> 
</Style> 

一個DataGrid，它似乎是這樣的：

在DataGrid失去焦點似乎我的問題：

我該如何讓我t的外觀與焦點無關嗎？

在嘗試查找解決方案之前，請查看DataGrid，DataGridRow等的Style/Template等Focus on Focus觸發器（IsFocused），因爲它不能作爲默認行爲。

如果沒有一個，嘗試添加EvenTriggers事件GotFocus和LostFocus這樣的：

<Window.Resources> 
    <SolidColorBrush x:Key="GotFocusColor" Color="Green" /> 
    <SolidColorBrush x:Key="LostFocusColor" Color="Transparent" /> 

    <Style TargetType="{x:Type DataGridRow}"> 
     <Setter Property="Foreground" Value="#FFB3B3B3"/> 
     <Setter Property="Height" Value="25"/> 
     <Setter Property="HorizontalContentAlignment" Value="Stretch"/> 

     <Style.Triggers> 
      <Trigger Property="IsSelected" Value="True"> 
       <Setter Property="Background" Value="#FF262626"/> 
      </Trigger> 

      <Trigger Property="ItemsControl.AlternationIndex" Value="0"> 
       <Setter Property="Background" Value="#FF383838"/> 
      </Trigger> 

      <Trigger Property="ItemsControl.AlternationIndex" Value="1"> 
       <Setter Property="Background" Value="#FF333333"/> 
      </Trigger> 

      <EventTrigger RoutedEvent="DataGrid.GotFocus"> 
       <BeginStoryboard> 
        <Storyboard> 
         <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background"> 
          <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="{StaticResource GotFocusColor}" /> 
         </ObjectAnimationUsingKeyFrames> 
        </Storyboard> 
       </BeginStoryboard> 
      </EventTrigger> 

      <EventTrigger RoutedEvent="DataGrid.LostFocus"> 
       <BeginStoryboard> 
        <Storyboard> 
         <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background"> 
          <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="{StaticResource LostFocusColor}" /> 
         </ObjectAnimationUsingKeyFrames> 
        </Storyboard> 
       </BeginStoryboard> 
      </EventTrigger> 
     </Style.Triggers> 
    </Style> 
</Window.Resources>
