删除WPF DatePickerTextBox周围的薄白框

我正在编写自定义日期选择器，我在设置颜色方面遇到了一些麻烦。

我将文本框和背景更改为黑色，但TextBox周围仍然有一个薄的白色矩形。将鼠标悬停在DatePickerTextBox字段上时，此空白区域将填充蓝色悬停颜色。无论如何要摆脱空白？

这是我的一些代码

<toolkit:DatePickerTextBox x:Name="PART_TextBox"                                                                       
     Grid.Row="0" Grid.Column="0" 
     Foreground="{StaticResource MenuForeground}"
     Background="{StaticResource MenuBackground}"
     BorderBrush="{StaticResource MenuBorder}" 
     HorizontalContentAlignment="Center"
     IsReadOnly="True"
     FontSize="12"
     FontFamily="Arial"
     HorizontalAlignment="Center"
     TextAlignment="Center"
     Focusable="False"
     FocusVisualStyle="{x:Null}"
     VerticalContentAlignment="Center" >
</toolkit:DatePickerTextBox>

这个日期时间选择器带有黑色文本框，周围没有薄白色矩形可能很有帮助
