C# 即使存在大量数据，WPF DataGrid也无法滚动

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

如你所见，底部有几行我看不见 即使我试着在下面突出显示，我仍然看不到下面的行

DataGrid

是从列表自动生成的。我已尝试设置垂直滚动条可见性&

水平滚动条可见性

，但仍然看不到其他数据

这是我的datagrid的XAML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>

你知道为什么我不能向下滚动并看到

DataGrid

下面的按钮吗？谢谢Polly的建议

我刚刚用ScrollViewer包装了我的StackPanel，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>

您可以将StackPanel替换为ScrollViewer，或将完整的xaml结构放入ScrollViewer中element@Polly我去看看

<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>
