    I am trying to navigate the map via the RadTreeViewItem rather than the ListBox

    I have the following code for the RadTeeViewItem:- 




    <telerikNavigation:RadTreeViewItem Header="Germany (3)" IsExpanded="True">  
           <mapNamespace:Location Description="Munich" Latitude="48.139126" Longitude="11.580186" />                         
           <mapNamespace:Location Description="Berlin" Latitude="52.5166667" Longitude="13.4" /> 
           <mapNamespace:Location Description="Frankfurt" Latitude="50.1166667" Longitude="8.6833333" />                          

    The problem is that that the Description is not displayed in the Tree. Just blank nodes.

    Hi Roland Ackermann,

    The RadTreeViewItem control is designed to work inside a RadTreeView control. The RadTreeView control is used to show hierarchical data and the best way to take advantage of this is to data bind the control to a hierarchical data source.

    However, it is possible to manually populate the tree view with nodes and data bind each of them. Here is a code that should work for you: 
                    <telerikNavigation:RadTreeView x:Name="RadTreeView1" >
                        <telerikNavigation:RadTreeViewItem x:Name="item1" DisplayMemberPath="Description" Header="Germany (3)" IsExpanded="True" />
    //Code Behind
            List<Location> locations = new List<Location>();           
    locations.Add(new Location(48.139126, 11.580186){ Description="Munich"});
                locations.Add(new Location(52.5166667, 13.4){ Description="Berlin"});
    item1.ItemsSource = locations;

    Hope this will help.

    Best wishes,
    the Telerik team
