WPF uses Hierarchicaldatatemplate binding dictionary to generate the TreeView

Dictionary in <string, Custometype>custometype is a collection that binds it to a tree, the first node of the tree is the dictionary key, the second layer is the Custometype collection, All code is implemented in XAML.

The code is as follows:

<treeview name= "Dictree" itemssource= "{Binding}" >

<TreeView.Resources>


<textblock text= "{Binding Id}" ><textblock text= "{Binding Name}" ></TextBlock></TextBlock>

</HierarchicalDataTemplate>

</TreeView.Resources>

<TreeView.ItemTemplate>


<textblock text= "{Binding Key}" ></TextBlock>

<HierarchicalDataTemplate.ItemTemplate>

<DataTemplate>

<textblock text= "{Binding Name}" ></TextBlock>

</DataTemplate>

</HierarchicalDataTemplate.ItemTemplate>

</HierarchicalDataTemplate>

</TreeView.ItemTemplate>

</TreeView>


Jobs JOBS1 = new jobs ();

Jobs1. ADD (New Job () {Id = 1, Name = "CEO1"});

Jobs1. ADD (New Job () {Id = 2, Name = "CEO2"});

Jobs1. ADD (New Job () {Id = 3, Name = "CEO3"});



Jobs JOBS2 = new jobs ();

JOBS2. ADD (New Job () {Id = 1, Name = "CEO1"});

JOBS2. ADD (New Job () {Id = 2, Name = "CEO2"});

JOBS2. ADD (New Job () {Id = 3, Name = "CEO3"});



dictionary<string, jobs> alljob = new dictionary<string, jobs> ();

Alljob.add ("CEO One", JOBS1);

Alljob.add ("CEO", JOBS2);

Dictree. DataContext = Alljob;


public class Job

{

public int Id

{get; set;}

public string Name

{get; set;}

public string Status

{get; set;}

}
public class Jobs:system.collections.objectmodel.observablecollection<job> {}
