WPF DataGrid - highlight Selected row even when SelectedItem is a bound property
提问by Bob Tway
I've got a WPF DataGrid where the SelectedItem is bound to a ViewModel property.
我有一个 WPF DataGrid，其中 SelectedItem 绑定到 ViewModel 属性。
SelectedItem="{Binding DataContext.SelectedBooking, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"
If a user clicks on a Row, selecting it, the only visual clue is that the gray background of the row becomes very slightly lighter. I need to make this more obvious, so I tried adding these, individually:
如果用户点击一行，选择它，唯一的视觉线索是该行的灰色背景变得非常浅。我需要让这更明显，所以我尝试单独添加这些：
<DataGrid.RowStyle>
<Style TargetType="{x:Type DataGridRow}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Background" Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.RowStyle>
And
和
<DataGrid.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>
</DataGrid.Resources>
The result is the same. When a user single-clicks on a row it very briefly flashes red and then goes back to pale gray, although the Row actually remains as being Selected. If they click on it a second time, it goes red and stays red.
结果是一样的。当用户单击一行时，它会非常短暂地闪烁红色，然后返回浅灰色，尽管该行实际上仍处于选中状态。如果他们第二次点击它，它会变成红色并保持红色。
If I remove the Binding on SelectedItem, it works as expected. How can I make this work regardless of the Binding?
如果我删除 SelectedItem 上的绑定，它会按预期工作。无论绑定如何，我怎样才能使这项工作？

I found the answer myself, scrolling through the Intellisense for SystemColors. There's an InactiveSelection brush that you can override too.
我自己找到了答案，滚动浏览 SystemColors 的 Intellisense。您也可以覆盖一个 InactiveSelection 画笔。
<DataGrid.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Red"/>
</DataGrid.Resources>
