WPF：Treeview Item Root使用不同的模板然后使用子节点

I currently am trying to bind my business object to a treeview as the root. And its collection property as the child. [I want to achieve this via BINDING]

我目前正在尝试将我的业务对象绑定到树视图作为根。而它的收藏属性就像孩子一样。 [我希望通过BINDING实现这一目标]

Something like this.

像这样的东西。

public object MyBusinessObject
{
   private int _number;
   private bool _isSelected;
   private ObservableCollection<AnotherObject> _other = new ObservableCollection<AnotherObject>();


   public int Number { get {return _number;} set {_number = value;}}
   public bool IsSelected{ get {return _isSelected;} set {_isSelected= value;}}
   public ObservableCollection<AnotherObject>  Children { get {return _other;}}

}

I want my treeview to be represented like this:

我希望我的treeview像这样表示：

• "CheckBox binded to IsSelected" "Text binded to Number"
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
• “CheckBox绑定到IsSelected”“文本绑定到数字”绑定到我的“孩子”的孩子的列表绑定到我的“孩子”的孩子的列表绑定到我的“孩子”的孩子的列表
• "CheckBox binded to IsSelected" "Text binded to Number"
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
  • List of child binded to my "Children"
  • 绑定到我的“孩子”的孩子一览
• “CheckBox绑定到IsSelected”“文本绑定到数字”绑定到我的“孩子”的孩子的列表绑定到我的“孩子”的孩子的列表绑定到我的“孩子”的孩子的列表

I have no idea how to do this in xaml:

我不知道如何在xaml中执行此操作：

  <TreeView x:Name="_tv" ItemsSource="{Binding Path=MyBusinessObject}" >

            <TreeView.Resources>
                <HierarchicalDataTemplate> 
                    <CheckBox Content="{Binding Path=Number} IsChecked="{Binding Path=IsSelected}" />
                </HierarchicalDataTemplate>

                <HierarchicalDataTemplate ItemsSource="{Binding Path=Children}">
                    <TextBlock Text="{Binding Path=Name}" />
                </HierarchicalDataTemplate>
            </TreeView.Resources>
        </TreeView>

I know the above is not right, but i was wondering if there is a way to do this properly.

我知道以上是不对的，但我想知道是否有办法正确地做到这一点。

Thanks and Regards,

Sure, you can use the HierarchicalDataTemplate.ItemTemplate property to define the data template to be used for the collection of AnotherObject instances.

当然，您可以使用HierarchicalDataTemplate.ItemTemplate属性来定义要用于AnotherObject实例集合的数据模板。

<TreeView ItemsSource="{Binding SomeCollectionOfObjects}">
    <TreeView.ItemTemplate>
        <HierarchicalDataTemplate ItemsSource="{Binding Children}">

            <!-- This is used for your AnotherObject instances -->
            <HierarchicalDataTemplate.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}" />
                </DataTemplate>
            </HierarchicalDataTemplate.ItemTemplate>

            <!-- This is used for your MyBusinessObject instances -->
            <CheckBox Content="{Binding Number}" IsChecked="{Binding IsSelected}" />

        </HierarchicalDataTemplate>
    </TreeView.ItemTemplate>
</TreeView>
