WPF 文本框高度等于父高度减去 50 像素？

我成功地让文本框根据父边框高度调整大小，但我需要文本框的高度实际上比父边框小 50 像素。

有什么想法如何实现这一目标？

我正在使用的代码是

<Border VerticalAlignment="Stretch" HorizontalAlignment="Stretch" >
     <TextBox x:Name="txtActivityNotes" HorizontalAlignment="Stretch" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Border}}, Path=ActualHeight}" AcceptsReturn="True" VerticalContentAlignment="Top" TextWrapping="WrapWithOverflow" VerticalScrollBarVisibility="Auto" />
</Border>

I'm successfully getting a TextBox to resize with a parent Border height but I need the TextBox to actually be 50 pixels smaller in height than the parent Border.

Any ideas how to achieve this?

The code I'm using is

<Border VerticalAlignment="Stretch" HorizontalAlignment="Stretch" >
     <TextBox x:Name="txtActivityNotes" HorizontalAlignment="Stretch" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Border}}, Path=ActualHeight}" AcceptsReturn="True" VerticalContentAlignment="Top" TextWrapping="WrapWithOverflow" VerticalScrollBarVisibility="Auto" />
</Border>

下边距不能设置为50吗？

<TextBox Margin="0,0,0,50" />

Can't you just set a bottom margin of 50?

<TextBox Margin="0,0,0,50" />

我尝试过遵循并且有效。
将以下内容添加到 xaml 中的文本框：

------
VerticalAlignment="Stretch" 
HorizontalAlignment="Stretch" 
Height="{Binding RelativeSource={RelativeSource FindAncestor, *AncestorType*={x:Type *Grid*}}, Path=ActualHeight}"
------

这里，AncestorType 是包含文本框的容器的类型。就我而言，它是“网格”。
并且还添加边距，

  Margin="0,0,0,50"

以与下面的边框保持距离。

I've tried following and it works.
add following to text box in xaml:

------
VerticalAlignment="Stretch" 
HorizontalAlignment="Stretch" 
Height="{Binding RelativeSource={RelativeSource FindAncestor, *AncestorType*={x:Type *Grid*}}, Path=ActualHeight}"
------

Here, AncestorType is type of container containing the textBox. In my case it was 'Grid'.
And also add margin like,
