    <TextBlock Text="{Binding Text}"></TextBlock>
</telerik:HierarchicalDataTemplate>

<telerik:RadPanelBar ItemTemplate="{StaticResource RadpaneItem}" />

CS file

void radPanelBar_Selected(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            RadPanelBarItem pbBarItem = e.Source as RadPanelBarItem;
            TextBlock Header    = pbBarItem.Header as TextBlock;
        }

Header return null value and i can't get the name of selected item

Hello bò,

Please have a look at the attached project as it demonstrates one possible solution to this scenario. However, my recommendation is not to look in the visual structure of the HierarchicalDataTemplate unless it is really necessary. The reason is that traversing the visual tree is an expensive operation and can lead to performance penalties.
