更改窗口高度时，文本在文本框中移动

Question

我的文本框有问题，每次更改窗口的高度时，文本框中的文本都会向上移动，在某些情况下会完全消失。对我来说这没有任何意义，也许有人可以帮助我并解释为什么会出现问题。当我试图让你的应用程序响应时，我发现很难理解为什么它的行为不像你希望的那样

Answer 1

您可以将 TextBox 包装在 ViewBox 中，如下所示：

<Viewbox Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Stretch="Fill" StretchDirection="DownOnly" Margin="10" >
    <TextBox Background="White" VerticalContentAlignment="Center" IsReadOnly="True" Name="TextResault" Height="160"  Width="1420" FontSize="80" Text="10110101"/>
</Viewbox>

这会缩放您的文本框及其字体大小。
