基于项目文件夹结构的 Wpf Treeview 绑定

发布于 2024-10-15 14:53:43 字数 485 浏览 4 评论 0原文

我目前有一个文件目录，我想读入我的项目中的程序。结构。

Project
   - Properties
   - References
   - Manufacturers (want to project this as treeview)
      - Honda
         - file1
         - file2
      - Toyota
         - file1
         - file2

在我的程序中，上面的每个文件都由其自己的业务对象表示。我希望能够在我的程序中将其显示在我的树视图中。

- Honda
     - file1
     - file2
- Toyota
     - file1
     - file2

我只加载这些文件一次，所以我只想读取这些文件一次并将它们绑定到树视图。有没有一种优雅的方法来做到这一点？？？

谢谢，凯夫

I currently have a catalog of files I want to read into my program in my Project.
Structure.

Project
   - Properties
   - References
   - Manufacturers (want to project this as treeview)
      - Honda
         - file1
         - file2
      - Toyota
         - file1
         - file2

In my program each file above is represented by its own business object.
I want to be able to in my program have this in my treeview.

- Honda
     - file1
     - file2
- Toyota
     - file1
     - file2

I only load these file once so I want to just read these file once and bind them to the tree view. Is there an elegant way to do this???

Thanks,
Kev

您可以使用 HierarchicalDataTemplate

<toolkit:HierarchicalDataTemplate x:Key="FileTemplate" >
       <TextBlock Text="{Binding Path=FileName}" />
</toolkit:HierarchicalDataTemplate>
<toolkit:HierarchicalDataTemplate x:Key="ManufacturerTemplate" 
        ItemsSource="{Binding Path=Files}" 
        ItemTemplate="{StaticResource FileTemplate}">
        <TextBlock Text="{Binding Path=Name}"/>
</toolkit:HierarchicalDataTemplate>

<toolkit:TreeView ItemsSource="{Binding}" 
    ItemTemplate="{StaticResource ManufacturerTemplate}"/>

您的业务对象可能看起来像这样...

class Manufacturer
{
     String Name {get; set;}
     ObservableCollection<File> Files {get; set;}

}

class File
{
     String FileName {get; set;}
}

然后，您可以将 TreeView 的 DataContext 设置为 ObservableCollection

You can make use of a HierarchicalDataTemplate

<toolkit:HierarchicalDataTemplate x:Key="FileTemplate" >
       <TextBlock Text="{Binding Path=FileName}" />
</toolkit:HierarchicalDataTemplate>
<toolkit:HierarchicalDataTemplate x:Key="ManufacturerTemplate" 
        ItemsSource="{Binding Path=Files}" 
        ItemTemplate="{StaticResource FileTemplate}">
        <TextBlock Text="{Binding Path=Name}"/>
</toolkit:HierarchicalDataTemplate>

<toolkit:TreeView ItemsSource="{Binding}" 
    ItemTemplate="{StaticResource ManufacturerTemplate}"/>

Your business objects could look something like this...

class Manufacturer
{
     String Name {get; set;}
     ObservableCollection<File> Files {get; set;}

}

class File
{
     String FileName {get; set;}
}

You would then set the DataContext of the TreeView to ObservableCollection<Manufacturer>
