即使有很多数据，WPF DataGrid 也无法滚动

Question

我有一个DataGrid，当我将数据加载到其中时，我无法向下滚动

这就是 DataGrid 的样子

如您所见，底部有几行我看不到即使当我尝试将高亮显示在下方时，我仍然看不到下方的行。

DataGrid 是从列表中自动生成的。我已经尝试设置 VerticalScrollBarVisibility & HorizontalScrollBarVisibility 但我仍然看不到其他数据。

这是我的 XAML 数据网格代码

<StackPanel Orientation="Vertical" Margin="0,0,0,0" Grid.Row="1">
                        <DataGrid
                            x:Name="dgvAttendance"

                            Margin="0,20"
                            CanUserSortColumns="True"
                            CanUserAddRows="False" SelectedIndex="0" AlternationCount="2" AutoGenerateColumns="True" SelectionMode="Single" EnableColumnVirtualization="True" IsReadOnly="True" ScrollViewer.CanContentScroll="False" CanUserReorderColumns="False" CanUserResizeColumns="False" HeadersVisibility="All" CanUserResizeRows="False" PreviewMouseWheel="DgvAttendance_PreviewMouseWheel" />

                        <Button
                            x:Name="btnExportExcel"
                            Style="{StaticResource MaterialDesignRaisedDarkButton}"
                            Width="110"
                            ToolTip="Resource name: MaterialDesignRaisedLightDarkButton" Margin="15,10" Content="Export File" HorizontalAlignment="Right" Click="BtnExportExcel_Click"  />
                    </StackPanel>

数据网格上还有一个我看不到的按钮

这是我加载数据网格的代码

public void Main()
        {

            actuals = NewActual(@"C:\Users\IT\Desktop\Sample\SampleActual.dat");
            emps = GetEmp();

            var final = (from t1 in actuals
                         join t2 in emps on t1.ID equals t2.ID
                         where t1.ID == t2.ID
                         orderby t2.ID
                         select new
                         {
                             t1.ID,
                             t2.In,
                             t1.ActualLog
                         });

            dgvAttendance.ItemsSource = final.ToList();
        }

为什么我无法向下滚动并看到 DataGrid 下方的按钮？谢谢

根据 Polly 的建议

我刚刚用 ScrollViewer 包装了我的 StackPanel，所以它看起来像这样

<ScrollViewer Grid.Row="1">
                        <StackPanel Orientation="Vertical" Margin="0,0,0,0" >

                        <DataGrid
                            x:Name="dgvAttendance"

                            Margin="0,20"
                            CanUserSortColumns="True"
                            CanUserAddRows="False" SelectedIndex="0" AlternationCount="2" AutoGenerateColumns="True" SelectionMode="Single" EnableColumnVirtualization="True" IsReadOnly="True" ScrollViewer.CanContentScroll="False" CanUserReorderColumns="False" CanUserResizeColumns="False" HeadersVisibility="All" CanUserResizeRows="False" PreviewMouseWheel="DgvAttendance_PreviewMouseWheel" >
                        </DataGrid>

                        <Button
                            x:Name="btnExportExcel"
                            Style="{StaticResource MaterialDesignRaisedDarkButton}"
                            Width="110"
                            ToolTip="Resource name: MaterialDesignRaisedLightDarkButton" Margin="15,10" Content="Export File" HorizontalAlignment="Right" Click="BtnExportExcel_Click"  />
                    </StackPanel>
                    <!-- Stack for Datagrid Ends Here -->
                    </ScrollViewer>
