如何阻止 WPF TextBox 增长

Question

当输入长文本时，WPF TextBox 控件会增长。

这个问题已经在 Stackoverflow 中提出了
，我也参考了很少的答案，但我仍然没有找到正确的答案。

这里提到了同样的问题，但没有针对此类问题的有效解决方案。

我已经花了足够的时间来解决这个问题，请帮助我解决这个问题。

  <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
        <DockPanel LastChildFill="False" Grid.IsSharedSizeScope="True">
            <GroupBox DockPanel.Dock="Top" DataContext="{Binding Data, ValidatesOnNotifyDataErrors=False}">
