将画笔添加到DataGrid的资源中，可以从后面的代码中更改其 Color属性，并对其进行引用HighlightBrushKey：

Add to DataGrid's resources the brush, which can change its 'Color' property from code behind, and reference HighlightBrushKey to it:

<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>

然后添加DataGrids事件处理程序以手动更改颜色：

Then add DataGrids event handlers to manually change the color:

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; }
