如何在按钮点击处理程序中更好地获取类数据

我的问题是，是否可以以更优雅、更高效的方式重做工作解决方案。我不想在MVVM模式中重新制作整个东西，我更想的是将信息从点击处理程序传递到点击处理程序的更好方法，而不是将其内容的按钮剥离。

目的是有两个独立的员工列表——左边的列表是一个完整的员工列表，右边的列表是分配给某项任务的员工列表。

主页.XAML

    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="1*"/>
            <ColumnDefinition Width="1*"/>
        </Grid.ColumnDefinitions>
        <GridView Grid.Column="0" x:Name="LeftGridView" ItemsSource="{Binding}">
            <GridView.ItemTemplate>
                <DataTemplate>
                    <Button Width="200" Height="200" Click="LeftListButtonClick" Background="Aqua">
                        <Button.Content>
                            <StackPanel Orientation="Vertical">
                                <Image Source="{Binding Photo}" Width="60" Height="60"/>
                                <TextBlock Width="100" Height="20" Text="{Binding FirstName}"/>
                                <TextBlock Width="100" Height="20" Text="{Binding Lastname}"/>
                            </StackPanel>
                        </Button.Content>
                    </Button>
                </DataTemplate>
            </GridView.ItemTemplate>
        </GridView>
        <GridView Grid.Column="1" x:Name="RightGridView" ItemsSource="{Binding}">
            <GridView.ItemTemplate>
                <DataTemplate>
                    <Button Width="200" Height="200" Click="RightListButtonClick" Background="Aqua">
                        <Button.Content>
                            <StackPanel Orientation="Vertical">

                </DataTemplate>
            </GridView.ItemTemplate>
        </GridView>
    </Grid>

类

class Person
{
    public String FirstName { get; set; }
    public String Lastname { get; set; }
    public Image Photo { get; set; }
}
class PersonList : ObservableCollection<Person>
{
    private ObservableCollection<Person> _leftList = new ObservableCollection<Person>();
    public ObservableCollection<Person> LeftList
    {
        get { return _leftList; }
        set { _leftList = value; }
    }
    private ObservableCollection<Person> _rightList = new ObservableCollection<Person>();
    public ObservableCollection<Person> RightList
    {
        get { return _rightList; }
        set { _rightList = value; }
    }    
}

最后是主页.XAML.CS

public sealed partial class MainPage : Page
{
    PersonList newList = new PersonList();
    public MainPage()
    {
        this.InitializeComponent();
        Person p1 = new Person();
        p1.FirstName = "John";
        p1.Lastname = "Doe";
        newList.LeftList.Add(p1);
        Person p2 = new Person();
        p2.FirstName = "Jane";
        p2.Lastname = "Doe";
        newList.LeftList.Add(p2);
        LeftGridView.ItemsSource = newList.LeftList;
    }
    private void LeftListButtonClick(object sender, RoutedEventArgs e)
    {
        Button var = sender as Button;
        StackPanel var2 = var.Content as StackPanel;
        var var3 =  var2.Children.ToArray();
        Person p1 = new Person();
        TextBlock tb1 = var3[1] as TextBlock;
        p1.FirstName = tb1.Text;
        TextBlock tb2 = var3[2] as TextBlock;
        p1.Lastname = tb2.Text;
        newList.RightList.Add(p1);
        RightGridView.ItemsSource = newList.RightList;
    }
    private void RightListButtonClick(object sender, RoutedEventArgs e)
    {
        throw new NotImplementedException();
    }
}

ICommand _addToRightCommand = new DelegateCommand<Person>(person => this.RightList.Add(person))
