防止文本框在 WPF 中水平扩展 [英] Prevent a TextBox from horizontal expanding in WPF

问题描述

我在 App.xaml 中定义了以下样式

I have the following style defined in my App.xaml

<Style x:Key="textBoxMultiline" TargetType="{x:Type TextBox}" >
    <Setter Property="VerticalScrollBarVisibility" Value="Auto" />
    <Setter Property="HorizontalScrollBarVisibility" Value="Hidden" />
    <Setter Property="MinHeight" Value="50" />
    <Setter Property="TextWrapping" Value="Wrap" />
</Style>

在整个解决方案中，我们在需要简短文本的每个文本框上都使用它.

And throughout the solution we're using it on every text box that needs a brief text.

<TextBox x:Name="textBoxDescription" Grid.Row="2" Grid.Column="1" Style="{DynamicResource textBoxMultiline}" />

一切都很好，但随后客户抱怨某些字段在分辨率较低的旧显示器上堆积，因此我在较高的可视化树节点之一上放置了 ScrollViewer 以防止堆积.

Everything works great, but then the client complains about some fields were corped on older monitors with lower resolutions, so I placed a ScrollViewer on one of the higher visual tree nodes to prevent the corping.

<ScrollViewer Height="Auto" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
   ...
</ScrollViewer>

奇怪的是，具有上述样式的 TextBox 开始向右扩展而不是包裹文本.

Strangely, the TextBoxes with the above style start expanding to the right instead of wrapping the text.

有没有办法在不删除 ScrollViewer 的情况下防止这种情况发生?

Is there a way to prevent this without removing the ScrollViewer?

推荐答案

你必须为 TextBox 定义一个 MaxWidth，否则没有限制，因为 ScrollViewer.

You must define a MaxWidth for the TextBox, otherwise there's no limit because the ScrollViewer.
