使WPF TextBox只有它所拥有的房间宽,但是当空间扩展时会扩展吗？

Question

注意文本框如何向右扩展,直到它有足够的水平空间来容纳内容？好吧,我希望它不会扩展和适应文本与窗口中的空间.

如果窗口扩展,那么它所在的Grid.Column将展开,但文本框本身应该展开以适应.够简单吗？

有什么建议？这是我第一次涉足WPF,到目前为止,它非常流畅.

要使TextBox包装在ListBox中,您可以进行以下更改:

1. 使用以下命令设置列表框的内容等于列表框的宽度:Horizo​​ntalContentAlignment ="Stretch".
2. 禁用列表框的水平滚动条以防止列表框获得所需的控件大小并阻止文本框中的自动换行.
3. 在TextBox中设置TextWrapping ="Wrap"

这是XAML:

<ListBox Grid.Row="1" x:Name="lstGames" Background="#343434" Padding="5" 
         ScrollViewer.HorizontalScrollBarVisibility="Disabled"
         HorizontalContentAlignment="Stretch" >
</ListBox>

<TextBox Text="{Binding Synopsis}" MinHeight="76" TextWrapping="Wrap" />
