更改 StackPanel 中的可见性

我有一个 WPF StackPanel，如下所示：（删除了一些无关紧要的属性）

<StackPanel HorizontalAlignment="Center" Name="PICStack">
        <Label Name="PICName"  MouseDoubleClick="PICName_MouseDoubleClick" />
        <TextBox Name="PICData" Width="120" Visibility="Hidden" />
        <Label Name="PICWeight" />
        <Label Name="PICARM"    />
</StackPanel>

请注意，文本框以“隐藏”开头。

当我双击顶部标签时，我交换了可见性：

private void PICName_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    this.PICData.Visibility = Visibility.Visible;
    this.PICName.Visibility = Visibility.Hidden;
}

目的是隐藏标签，并使文本框出现在其位置。

但是，由于它是 StackPanel，因此 TextBox 会占用垂直空间，即使它不可见也是如此。然后，当文本框显示时，它上面有空白区域，标签以前是可见的。

有没有一种好方法可以使这两个项目本质上直接位于彼此之上？这样双击标签似乎突然变成了文本框？

I have a WPF StackPanel that looks like this:
(some attributes removed that don't matter)

<StackPanel HorizontalAlignment="Center" Name="PICStack">
        <Label Name="PICName"  MouseDoubleClick="PICName_MouseDoubleClick" />
        <TextBox Name="PICData" Width="120" Visibility="Hidden" />
        <Label Name="PICWeight" />
        <Label Name="PICARM"    />
</StackPanel>

Note that the TextBox starts as "Hidden".

When I double-click on the top label, I swap the visibility:

private void PICName_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    this.PICData.Visibility = Visibility.Visible;
    this.PICName.Visibility = Visibility.Hidden;
}

The intent is to hide the label, and make the TextBox appear in its place.

However, because it is a StackPanel, the TextBox takes up vertical space, even when it is not visible. Then, when the TextBox is revealed, it has blank space above it, where the Label was previously visible.

Is there a good way to make the two items essentially be directly on top of each other? so that double-clicking the Label appears to suddenly change into a TextBox?
