如何删除wpf顶部显示的验证显示错误框？

在我的wpf用户控件中，我有一个带有错误验证框的文本框 . 它工作正常 . 但是当我减小屏幕尺寸时，当文本框和其他控件沿着面板向下移动时，错误框会出现在文本框旁边的下一个面板的顶部 . 如何使其正常工作？

这是xaml代码：

<UserControl.Resources>
        <BitmapImage x:Key="DefaultUser"
                     UriSource="/Capstone_ERP;component/Images/default-user-image.jpg" />
        <ControlTemplate x:Key="LeftErrorTemplate">
            <StackPanel Orientation="Vertical">
