TreeView and binding my class

[Artem]

Hi.
I have class

public class User
{
public int Id {get; set;}
public string Name{get;set;}
public string phone{get;set;}
public List<User> userList {get; set;}
}

How can I bind list with this type data to treeView.
I've try  this:

<telerik:RadTreeView x:Name="userTree" >
                    <telerik:RadTreeView.ItemTemplate>
                        <telerik:HierarchicalDataTemplate>
                            <TextBlock Text="{Binding Name}"/>
                        </telerik:HierarchicalDataTemplate>
                    </telerik:RadTreeView.ItemTemplate>

                </telerik:RadTreeView>

 But I see only root element.

Hi sharp,

You have to set the ItemsSource of the HierarchicalDataTemplate like so:

<telerik:RadTreeView.ItemTemplate>
                        <telerik:HierarchicalDataTemplate ItemsSource={Binding userList}>
                            <TextBlock Text="{Binding Name}"/>
                        </telerik:HierarchicalDataTemplate>
                    </telerik:RadTreeView.ItemTemplate>

You can also check out the attached project and this help article if you need more info. Let us know if this helped you. Additionally, it is better practice to use ObservableCollection instead of List since it inherits from INotifyCollectionChanged and INotifyPropertyChanged and this way every change in the ViewModel will be automatically reflected in the UI.
