在uwp中使用带有多选复选框的mytoolkit datagrid

<Page
    xmlns:mytoolkit="using:MyToolkit.Controls"
    ...>
    
    <Grid>
        <mytoolkit:DataGrid x:Name="myDataGrid" AutoGenerateColumns="False">
            <!-- 添加列定义 -->
            <mytoolkit:DataGrid.Columns>
                <mytoolkit:DataGridCheckBoxColumn Header="选择" Binding="{Binding IsSelected}" Width="50" />
                <!-- 其他列定义 -->
            </mytoolkit:DataGrid.Columns>
        </mytoolkit:DataGrid>
    </Grid>
</Page>

public class MyDataModel : INotifyPropertyChanged
{
    private bool isSelected;
    public bool IsSelected
    {
        get { return isSelected; }
        set
        {
            isSelected = value;
            OnPropertyChanged(nameof(IsSelected));
        }
    }
    
    // 其他属性
    
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

// 在页面的代码中使用数据模型
public MainPage()
{
    InitializeComponent();
    List<MyDataModel> data = new List<MyDataModel>
    {
        new MyDataModel { IsSelected = false },
        new MyDataModel { IsSelected = false },
        // 添加其他数据
    };
    myDataGrid.ItemsSource = data;
}
