WPF: TreeView Item Root uses a different template and then child nodes

Question

I'm currently trying to associate my business object with a tree as a root. And his collection property is like a child. [I want to achieve this through BINDING]

Something like that.

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 tree view to be presented as follows:

• "CheckBox bound to IsSelected" "Text bound to Number"
  • List of children attached to my "children"
  • List of children attached to my "children"
  • List of children attached to my "children"
• "CheckBox bound to IsSelected" "Text bound to Number"
  • List of children attached to my "children"
  • List of children attached to my "children"
  • List of children attached to my "children"

I don't know how to do this in xaml:

  <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 this is wrong, but I was wondering if there is a way to do it right.

Thanks and respect,

, HierarchicalDataTemplate.ItemTemplate, , AnotherObject.

<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>
