如何在DataGrid.RowDetailsTemplate中访问文本块中的数据

<DataGrid>
    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <!-- 在这里定义RowDetailsTemplate的内容 -->
            <TextBlock Text="{Binding YourProperty}" />
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>
</DataGrid>

public class YourDataModel : INotifyPropertyChanged
{
    private string yourProperty;
    public string YourProperty
    {
        get { return yourProperty; }
        set
        {
            if (yourProperty != value)
            {
                yourProperty = value;
                OnPropertyChanged(nameof(YourProperty));
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

YourDataModel dataModel = new YourDataModel();
dataModel.YourProperty = "Your Text";

dataGrid.ItemsSource = new List<YourDataModel> { dataModel };
