我在另一个 Grid 中有一个 Grid 并将第二个 Grid 添加到 ScrollViewer 但看不到它的滚动条。我添加的 ScrollViewer 网格的名称为InfoGrid。我不明白为什么 ScrollViewer 不起作用。你有什么替代方法可以建议我吗？我的所有窗口的 xaml 代码：

<Window x:Class="ModelView.KillCardCheck"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Width="Auto" Height="Auto" SizeToContent="WidthAndHeight"
        ResizeMode="NoResize" Icon="pack://application:,,,/Resources/image/ffdc_gui.png"
        xmlns:lex="http://schemas.root-project.org/xaml/presentation" Closing="WindowClosing">

            <RowDefinition/>
            <RowDefinition Height="40"/>

            </DataGrid.Columns>

    </Grid>

您制作的 ScrollViewer 没有设置 grid.Row，而是将其放在其中的网格上。这没有多大意义，因为网格（“信息网格”）位于 ScrollViewer 内部，因此它的父级是 ScrollViewer。您可能想尝试设置 ScrollViewer 行和列。
