c# - 如何更改 DataGrid Mahapp 中选定行的颜色

Question

我正在尝试更改所选行的颜色，但没有结果。 我已经尝试过这个:

<DataGrid Style="{StaticResource AzureDataGrid}">

但我能看到的唯一变化是第一列由天蓝色着色。 当我选择一行时，它会变成白色，并且我看不到所选行上的值。我是这个 framework 主题 wpf 的新手，文档不准确。有人可以帮助我吗？

现在可以使用 MahApps.Metro 的最新 Alpha 版本(1.1.3.x 或更高版本 1.2.0)更改选定的行画笔

这是主要演示中的示例

<DataGrid x:Name="MetroDataGrid"
            Grid.Column="1"
            Grid.Row="1"
            RenderOptions.ClearTypeHint="Enabled"
            TextOptions.TextFormattingMode="Display"
            HeadersVisibility="All"
            Margin="5"
            SelectionUnit="FullRow"
            ItemsSource="{Binding Path=Albums}"
            AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridCheckBoxColumn ElementStyle="{DynamicResource MetroDataGridCheckBox}"
                                EditingElementStyle="{DynamicResource MetroDataGridCheckBox}"
                                Header="IsSelected"
                                Binding="{Binding RelativeSource={RelativeSource AncestorType=DataGridRow}, Path=IsSelected, Mode=OneWay}" />
        <DataGridTextColumn Header="Title"
                            Binding="{Binding Title}" />
        <DataGridTextColumn Header="Artist"
                            Binding="{Binding Artist.Name}" />
