C# WPF自定义控件/控件模板

我正在使用自定义控件构建一个wpf应用程序，到目前为止一切都正常。
但现在我遇到了两个问题：

我想为我的控件指定一个背景色，但它会覆盖网格内的矩形，因此矩形不可见

我试图为ContentControl编写一个模板，但内容没有按预期呈现，这意味着只有显示名称显示在每个进度条的文本中 自定义控件的模板（如果对隐藏的代码感兴趣，我也将添加该模板）：

ContentControl的模板：

<vm:RamViewModel x:Key="RamInformationSource"/>

<Style TargetType="ContentControl" x:Key="MemoryUsageTemplate">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <Grid DataContext="{Binding Source={StaticResource RamInformationSource}}">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>

                    <TextBlock HorizontalAlignment="Center" Text="{Binding DisplayName}" VerticalAlignment="Center"
                               FontSize="15"/>

                    <ctrl:MetroProgressBar Grid.Column="1" VerticalAlignment="Stretch" Width="55" Orientation="Vertical" HorizontalAlignment="Center"
                                           ExtenedBorderWidth="0.25" BorderBrush="Gray" Text="Available memory" Progress="{Binding AvailableMemory}"
                                           MaxValue="{Binding TotalMemory}"/>

                    <ctrl:MetroProgressBar Grid.Column="2" VerticalAlignment="Stretch" Width="60" Orientation="Vertical" HorizontalAlignment="Center"
                                           ExtenedBorderWidth="0.2" BorderBrush="Black" Text="Total memory" Progress="100"
                                           MaxValue="{Binding TotalMemory}"/>

                    <ctrl:MetroProgressBar Grid.Column="3" VerticalAlignment="Stretch" Width="60" Orientation="Vertical" HorizontalAlignment="Center"
                                           ExtenedBorderWidth="0.2" BorderBrush="DodgerBlue" Text="Used memory" Progress="{Binding UsedMemory}"
                                           MaxValue="{Binding TotalMemory}"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

显示内容的xaml：

...
<ContentControl Style="{StaticResource MemoryUsageTemplate}"/>

<ctrl:MetroProgressBar Grid.Row="1" BorderBrush="Black" Text="Test" HorizontalAlignment="Left" Background="Aquamarine"
                       Orientation="Horizontal" BorderThickness="2" Height="50" Width="200" Progress="46"/>

<ctrl:MetroProgressBar Grid.Row="1" BorderBrush="Black" Text="Test" HorizontalAlignment="Right"
                       Orientation="Horizontal" BorderThickness="2" Height="50" Width="200" Progress="46"/>
...  

。。。
...  

图像顶部显示应用了模板的内容控件。底部显示了上一个xaml中定义的两个进度条（左带背景，右不带背景）。 这些都是为控件定义的自定义DPs：
