DataGrid's selected row color when inactive
提问by white.zaz
How can I style WPF DataGrid to change the color of selected row when DataGrid lost its focus?
当 DataGrid 失去焦点时，如何设置 WPF DataGrid 的样式以更改所选行的颜色？

Find an answer by myself.
自己找答案。
Add to DataGrid's resources the brush, which can change its 'Color' property from code behind, and reference HighlightBrushKey to it:
将画笔添加到 DataGrid 的资源中，它可以从后面的代码中更改其“颜色”属性，并将 HighlightBrushKey 引用到它：
<DataGrid.Resources>
<SolidColorBrush x:Key="SelectionColorKey" Color="DarkGray"/>
<Style TargetType="DataGridRow">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="{Binding Source={StaticResource SelectionColorKey}, Path=Color}"/>
</Style.Resources>
</Style>
</DataGrid.Resources>
Then add DataGrids event handlers to manually change the color:
然后添加 DataGrids 事件处理程序以手动更改颜色：
private void DataGrid1_LostFocus(object sender, RoutedEventArgs e)
{
((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = Colors.DarkGray;
}
private void DataGrid1_GotFocus(object sender, RoutedEventArgs e)
{
((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = SystemColors.HighlightColor;
}
private void DataGrid1_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = Colors.DarkGray;
}

After ages of searching, I found a surprisingly simple way to do this that's cleaner than the Got/LostFocus approach posted earlier:
经过多年的搜索，我发现了一种非常简单的方法，它比之前发布的 Got/LostFocus 方法更简洁：
<DataGrid.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="DarkGray"/>
</DataGrid.Resources>
This just sets the inactive background colour to DarkGray, leaving the active background colour to the default, but you can change that too using the SystemColors.HighlightBrushKey too of course.
这只是将非活动背景颜色设置为 DarkGray，将活动背景颜色保留为默认值，当然您也可以使用 SystemColors.HighlightBrushKey 更改它。
The foreground resource key for inactive selections is SystemColors.InactiveSelectionHighlightTextBrushKey.
非活动选择的前景资源键是 SystemColors.InactiveSelectionHighlightTextBrushKey。

Complete solution that works for 4.0. Note that this on the CellStyle.
适用于 4.0 的完整解决方案。注意这个关于CellStyle。
<DataGrid.CellStyle>
<!--Override Highlighting so that its easy to see what is selected even when the control is not focused-->
<Style TargetType="{x:Type DataGridCell}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}" />
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
</Trigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsSelected}" Value="True" />
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=IsKeyboardFocusWithin}" Value="False" />
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}" />
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</Style.Triggers>
</Style>
</DataGrid.CellStyle>

Do it like this:
像这样做：
<DataGrid ...>
<DataGrid.Resources>
<Style TargetType="DataGridRow">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>
</Style.Resources>
</Style>
</DataGrid.Resources>
...

None of these answers gave me quite what I was looking for. The top rated by Steve Streeting changed other sections of the datagrid that I didn't want to change, and other answers weren't providing the inactivecolor change, but were properly targeting the row only. So here's a mixture of their answers that changes the inactivecolor, onlyon the rows and not in other places on the grid.
这些答案都没有给我我正在寻找的东西。Steve Streeting 评分最高的更改了我不想更改的数据网格的其他部分，其他答案并未提供非活动颜色更改，而是仅正确定位该行。所以这是他们的答案的混合，改变了非活动颜色，只在行上，而不是在网格的其他地方。
<DataGrid.Resources>
<Style TargetType="DataGridRow">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="DarkGray"/>
</Style.Resources>
</Style>
</DataGrid.Resources>

For .Net Framework 4.0 (or if you don't want to use the InactiveSelection... brush keys): Create a DataGridRowstyle/control template, and add these triggers:
对于 .Net Framework 4.0（或者如果您不想使用 InactiveSelection...刷键）：创建一个DataGridRow样式/控件模板，并添加以下触发器：
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" Value="{DynamicResource SelectionBrush}" />
</Trigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsSelected}" Value="True" />
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=IsKeyboardFocusWithin}" Value="False" />
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="Background" Value="{DynamicResource InactiveSelectionBrush}" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</ControlTemplate.Triggers>

LATE ANSWER:
迟到的回答：
This works in .Net 4.0, and you don't have to hardcode the color:
这适用于.Net 4.0，您不必对颜色进行硬编码：
<Style TargetType="DataGridRow">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{x:Static SystemColors.HighlightColor}" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="{x:Static SystemColors.HighlightTextColor}"/>
</Style.Resources>
</Style>

You should define section "DataGrid.CellStyle" inside your DataGrid like this:
您应该像这样在 DataGrid 中定义“DataGrid.CellStyle”部分：
<DataGrid>
<DataGrid.CellStyle>
<Style TargetType="DataGridCell">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="LightBlue"/>
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.CellStyle>
</DataGrid>

I added this to my ResourceDictionary so that it applies to all data grids in my program.
我将此添加到我的 ResourceDictionary 中，以便它适用于我程序中的所有数据网格。
<Style TargetType="DataGrid">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="LightGray"/>
</Style.Resources>
</Style>
