在WPF的TreeView分组子对象 [英] Grouping child objects in WPF TreeView

问题描述

我试图通过它们是什么让我的树视图将类似项目的集合。为了保持通用的，我的对象层次结构可能看起来像这样：

I am trying to get my tree view to group a collection of similar items by what they are. To keep things generic, my object hierarchy could look like this:

• 对象结果
  
  
  
  • 对象组＃1结果
    
    
    
    • 项目＃1（A型）
    
    
    • 项目＃2（类型 A'）
    
    
    • 物品＃3（类型'b'）
    
    
    • 物品＃4（类型'b'）
    
    
    • Objects
      
      • Object Group #1
        
        • Item #1 (Type 'A')
        • Item #2 (Type 'A')
        • Item #3 (Type 'B')
        • Item #4 (Type 'B')

        现在我的TreeView显示这些对象酷似对象模型，但我想这样做是插入为每个对象类型一个TreeView节点，以便它看起来是这样的：

        Right now my TreeView shows these objects exactly like the object model, but what I would like to do is insert a TreeView node for each object type so that it would look like this:

        
        
        • 对象结果
          
          
          
          • 对象组＃1结果
            
            
            
            • A型结果
              
              
              
              • 物品＃1
              
              
              • 物品＃2
              
              
              
              
              • 物品＃3
              
              
              • 物品＃4
              
              

              我在一个类似的问题在这里看到了有人建议有两个独立的 HierarchicalDataTemplates 所以我创建了一个包含同类型的列表一个TreeView'对象组＃1的水平，但是这是因为它真的很笨拙一些节点内部的完全独立的树视图。我也一直试图用一个 CollectionViewSource 来筛选出了每个类别的项目，但是这并不能帮我非常好，因为我无法弄清楚如何。显示他们

              I saw in a similar question here that someone recommended to have two separate HierarchicalDataTemplates so I created one for 'Object Group #1' level which contains a TreeView with a list of the types, but this is really clumsy since it is a whole separate TreeView inside of some nodes. I have also been trying to use a CollectionViewSource to filter out the items in each category, but this doesn't do me very much good since I can't figure out how to display them.

              我想我的问题归结为：我如何做一个 HierarchicalDataTemplate 组它的孩子吗？如果有人能在正确的方向指向我，我将不胜感激了很多。

              I guess my question boils down to this: How do I make a HierarchicalDataTemplate group it's children? If someone could point me in the right direction I would appreciate it a lot.

              我可以张贴一些代码，如果有人想看到的，但我真的只是想弄清楚如何做我想做的，所以我的代码只是一个非常简单的数据绑定TreeView的现在。

              I can post some code if anyone wants to see, but I am really just trying to figure out how to do what I want so my code is just a pretty straight forward databound treeview right now.
