WPF RichTextBox + StackPanel 中的按钮 =>真是一团糟？

此代码：

<StackPanel Orientation="Horizontal">
                <RichTextBox />
                <Button Content="Dialog" />  
            </StackPanel>

在 RichTextBox 上的 StackPanel 左侧某处显示按钮，为什么？

编辑：哦，我刚刚看到它的宽度问题。 RTB 几乎没有宽度，按钮位于其右侧。

编辑：似乎我遇到了这个错误： WPF RichTextBox with no width set

解决方案对我不起作用！

This code:

<StackPanel Orientation="Horizontal">
                <RichTextBox />
                <Button Content="Dialog" />  
            </StackPanel>

shows the button somewhere on the left side of the StackPanel ONTO the RichTextBox, WHY?

edit: Oh I just saw its a width problem. The RTB has nearly no width and the button is righthand of it.

edit: seems I run into this bug: WPF RichTextBox with no width set

solution does not work for me!

您最好使用 Grid 和 RTB 的 HorizontalAlignment （和 VerticalAlignment）属性。

<Grid HorizontalAlignment="Stretch"
      VerticalAlignment="Stretch">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <RichTextBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Column="1" 
            Content="Dialog" 
            HorizontalAlignment="Right" 
            VerticalAlignment="Bottom" />
</Grid>

You'd be better off using a Grid and the HorizontalAlignment (and VerticalAlignment) properties of the RTB.

<Grid HorizontalAlignment="Stretch"
      VerticalAlignment="Stretch">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <RichTextBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Column="1" 
            Content="Dialog" 
            HorizontalAlignment="Right" 
            VerticalAlignment="Bottom" />
</Grid>

你的代码布局应该是这样的：

<StackPanel Margin="105,73,124,54" Orientation="Horizontal">
                <RichTextBox Width="312" />
                <Button Content="Dialog" VerticalAlignment="Bottom" Height="56" />  
            </StackPanel>

你必须单独调整每个元素（控件）的大小，否则你会得到一个与最初的布局类似的布局（所有元素都混乱并压在一起。）

Your code layout should be something like:

<StackPanel Margin="105,73,124,54" Orientation="Horizontal">
                <RichTextBox Width="312" />
                <Button Content="Dialog" VerticalAlignment="Bottom" Height="56" />  
            </StackPanel>

You have to size each element (control) individually, otherwise you get a layout similar to what you have originally (all jumbled up and crushed together.)
