WPF DataGrid风格

Question

我有一个具有以下样式的DataGrid

<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>

它看起来像这样：

当DataGrid失去焦点时出现我的问题：

如何使其外观独立于焦点？

在您尝试查找解决方案之前，请查看DataGrid，DataGridRow等的Style/Template，以及Focus（IsFocused触发器）上的StyleTrigger，因为它不能是默认行为。

如果没有，请尝试为事件GotFocus和LostFocus添加EvenTriggers，如下所示：

<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>
