WPF Grid.IsSharedSizeScope 跨多个网格

Question

我遇到这样一种情况，我的按钮位于多个网格中，并且要求所有按钮的大小都相同。我尝试使用 Grid.IsSharedSizeScope 但没有成功。

最终布局应如下图所示，但所有按钮的大小应相同。

XAML目前看起来是这样的。有人看到我哪里出错了吗？

仅将 Grid.IsSharedSizeScope 应用于顶级容器。参考下面的代码。

<Grid Grid.IsSharedSizeScope="True">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
        </Grid.ColumnDefinitions>
        <GroupBox Grid.Row="0" Grid.Column="0" Header="Header 1" >
            <Grid >
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="Button" />
                    <ColumnDefinition Width="Auto" SharedSizeGroup="Button" />
                    <ColumnDefinition Width="Auto" SharedSizeGroup="Button" />
                </Grid.ColumnDefinitions>
                <Button Content="A" Grid.Row="0" Grid.Column="0" Margin="2" />
                <Button Content="B" Grid.Row="0" Grid.Column="1" Margin="2" />
                <Button Content="C" Grid.Row="0" Grid.Column="2" Margin="2" />
            </Grid>
        </GroupBox>
        <GroupBox Grid.Row="1" Grid.Column="0" Header="Header 2" >
            <Grid >
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="Button" />
                    <ColumnDefinition Width="Auto" SharedSizeGroup="Button" />
                </Grid.ColumnDefinitions>
                <Button Content="AA" Grid.Row="0" Grid.Column="0" Margin="2" />
                <Button Content="BB" Grid.Row="0" Grid.Column="1" Margin="2" />
            </Grid>
        </GroupBox>
    </Grid>
