TreeListView，由ObservableCollection生成和填充的列

问题描述

有没有人知道（甚至有一个例子）基于WPF的TreeListView，可以通过数据绑定到它的树项目的ObservableCollection来生成其列

例如，数据绑定模型是由表示公司的主管层次结构的Employee实例组成的树。每个员工都附加了一个ObservableCollection of Responsibility实例（属性：ResponsibiltyName，ResponsibleSinceDate）。现在我需要在任何一个数据绑定的Employees中找到每个ResponsibiltyName的一个单独的列，并且列值应该使用ResponsibleSinceDate填充。如果员工没有一定的责任，列值应该留空。

WPF中通常会遇到这样的问题？

解决方案

您可能需要查看以下答案：

这里提出了一个涉及CompositeCollection的解决方案：

这里提出了一个涉及HierarchicalDataTemplate的解决方案：

Does anyone known (or even has an example) of a WPF based TreeListView that can generate its colums by databinding to the ObservableCollection of its tree items?

For example the databound model is a tree consisting of Employee instances representing the supervisor hierarchy of a company. Each employee addtionally has a ObservableCollection of Responsibility instances (Properties: ResponsibiltyName, ResponsibleSinceDate). Now I want a separate column for each ResponsibiltyName found in any of the databound Employees and the column value should be populated with the ResponsibleSinceDate. If an Employee does not have a certain Responsibilty the column value shall be left blank.

How would one usually approach such a problem in WPF?
