Question

当我的窗口最大化时，滚动查看器出现问题。在网格中使用它似乎是错误的空间。滚动条改变大小，在底部“跳转”到最后并且不会出现更多。

StackPanel和ScrollViewer并没有很好地融合，看起来您的StackPanel在您的代码中没用，只需将Grid.Column直接设置在您的边框中，这应该可以解决问题。

此示例代码是您ScrollViewer元素的子代码吗？

<强>更新

手动执行此操作的一种简单方法是执行此操作：

<DockPanel>
    <ScrollViewer VerticalScrollBarVisibility="Auto" DockPanel.Dock="Top">
        // Your DataGrid
    </ScrollViewer>
</DockPanel>
