如何设置 MahApps Window 网格的样式？

Question

我正在为我的 WPF 应用程序使用 Mahapps UI 工具包，我需要放置在 MetroWindow 中的网格在应用程序未像 MetroWindow 那样处于活动状态时更改其颜色。我尝试了几种解决方案，但都是徒劳的：

<Grid Background="{DynamicResource AccentColorBrush}" >
                <TextBlock Text="Test" Foreground="#FFFFFF"  VerticalAlignment="Center" Padding="10,0,0,0"/>
</Grid>

此解决方案要么将网格颜色设置为 AccentColorBrush

<Grid Background="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=controls:MetroWindow}, Path=WindowTitleBrush}" >
                <TextBlock Text="Test" Foreground="#FFFFFF"  VerticalAlignment="Center" Padding="10,0,0,0"/>
</Grid>

我还可以使用 NonActiveWindowTitleBrush 将网格颜色设置为不活动属性

<Grid Background="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=controls:MetroWindow}, Path=NonActiveWindowTitleBrush}" >
                    <TextBlock Text="Test" Foreground="#FFFFFF"  VerticalAlignment="Center" Padding="10,0,0,0"/>
</Grid>

如有任何帮助，我将不胜感激。

此致，德米特里

试试这个：

<Controls:MetroWindow x:Class="MahApps.Metro.Application12.MainWindow"
                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                  xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
                  xmlns:Custom="http://metro.mahapps.com/winfx/xaml/shared" 
                  Title="MainWindow"
                  Height="350" 
                  Width="525">

<Controls:MetroWindow.Resources>

    <Style x:Key="GridStyle1" TargetType="{x:Type Grid}">
        <Setter Property="Background" Value="{StaticResource AccentColorBrush}"/>
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsActive, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Controls:MetroWindow}}}" Value="False">
                <Setter Property="Background"  Value="{StaticResource GrayBrush3}"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>

</Controls:MetroWindow.Resources>

<Grid x:Name="grid1" Margin="50" HorizontalAlignment="Center" VerticalAlignment="Center" Height="232" Width="409" Style="{StaticResource GridStyle1}">

    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="32" Text="{Binding IsActive, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Controls:MetroWindow}}}"/>

</Grid>
