WPF数据网格虚拟化

我试图通过对数据进行两级排列来绕过与WPF数据网格相关的虚拟化问题

    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <ListView Name="InnerGrid" ItemsSource="{Binding EmpCollection}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="EmpId">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Empid}">

                                    </TextBlock>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Name">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Country">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Empid}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Phone">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Phone}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Date">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Date}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                    </GridView>
                </ListView.View>
            </ListView>
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>

每个国家/地区的行为标题行，单击标题行可显示该国家/地区的员工

    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <ListView Name="InnerGrid" ItemsSource="{Binding EmpCollection}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="EmpId">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Empid}">

                                    </TextBlock>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Name">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Country">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Empid}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Phone">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Phone}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Date">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Date}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                    </GridView>
                </ListView.View>
            </ListView>
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>

本质上，我试图将datagrid的每个元素作为listview项

    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <ListView Name="InnerGrid" ItemsSource="{Binding EmpCollection}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="EmpId">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Empid}">

                                    </TextBlock>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Name">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Country">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Empid}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Phone">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Phone}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Date">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Date}">

                                </TextBlock>
                            </DataTemplate>

                    <GridView>
                        <GridViewColumn Header="EmpId">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Empid}">

                                <TextBlock Text="{Binding Name}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Country">

                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Phone">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Phone}">

                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Date">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Date}">

                                </TextBlock>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                    </GridView>
                </ListView.View>
            </ListView>
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>

我希望Country行跨越所有列，以便显示 像标题行一样

我不希望单击标题行时列标题显示在每个国家/地区的下方

我希望特定国家/地区数据行中的数据与主网格中的数据对齐 列

如果有其他更好的方法解决此问题，请提供详细信息/参考资料
