WPF绑定嵌套列表

Question

我试图在列表视图中显示这个嵌套列表。

例如，如果EventItem有响应，我需要在每个响应中重复事件名称x次。每个响应都有3个复选框。

我要做的是在一个列表中显示:

EventName -> Response Option -> Check Boxes of Effort.

我不想使用树，因此列表是单行的。什么好主意吗?

更新:

假设有2个事件，事件1有2个选项，事件2有3个选项。每个选项将有3个复选框。

我如何尝试显示数据是这样的:

Event 1         Response A       [X]   [ ]   [ ]
Event 1         Response B       [ ]   [X]   [X]
Event 2         Response A       [X]   [X]   [X]
Event 2         Response D       [ ]   [ ]   [X]
Event 2         Response E       [X]   [X]   [X]

对于Response，我需要重复事件名称。

public class EventItem: DataAttributeChecked
{
    public EventItem(int primaryKey, string value) : base(primaryKey, value)
    {
        ResponseOptions = new List<ResponseOption>();
    }
    public List<ResponseOption> ResponseOptions { get; set; }
}
public class ResponseOption: DataAttribute
{
    public ResponseOption(int primaryKey, string value, int eventId) : base(primaryKey, value)
    {
        _eventId = eventId;
        LevelOfEfforts = new List<DataAttributeChecked>();
    }
    public List<DataAttributeChecked> LevelOfEfforts { get; set; }
    private readonly int _eventId;
    public int EventId
    {
        get { return _eventId; }
    }
}

如果列表是嵌套的，你就有一个树，你可以使用HierarchicalDataTemplate并在TreeView或嵌套listview中显示。

如果您想在平面列表中查看，让你的ViewModel把树弄平，
