    I have a treeView using an ItemTemplate
    <ScrollViewer HorizontalScrollBarVisibility="Auto"
                  VerticalScrollBarVisibility="Auto" BorderThickness="0">
                                 <navi:RadTreeView x:Name="rdtreeCheckLists"
                                       SelectedItem="{Binding SelectedOrgCheckList, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"                                     
                                       ItemsSource="{Binding CheckListWithItems, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"
                                       ItemTemplate="{StaticResource CheckListTemplate}"

    Item template is like this

    <telerik:HierarchicalDataTemplate x:Key="CheckListTemplate" ItemsSource="{Binding SubItems,Mode=TwoWay}">
                <StackPanel Orientation="Horizontal">
                    <Image Source="../Images/add_to_group.jpg" Width="15" Height="15"></Image>
                    <TextBox Text="{Binding Name,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"
                             BorderThickness="0" BorderBrush="Transparent"
                             IsReadOnly="{Binding  RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=UserControl},
                                HorizontalAlignment="Right" Click="CheckListDelete_Click"                               
                                Width="Auto" Height="17"  CommandParameter="{Binding Id, Mode=TwoWay}"  CommandTarget="{Binding Type, Mode=TwoWay}" />

    I have binded a HierarchicalDataModel "CheckListWithItems" which has SubItems property. 

    The problem is in DragDrop Items into tree view. When i drop item into tree view the latter version it doesn't show dropped item as child. Even when i add it in code it shows only most upper level items. 

    The problem is in Telerik.Windows.Control RuntimeVersion v4.0.30319 / Version 2014.3.1202.1050 this WORKS. but NOT in  RuntimeVersion v4.0.30319 / Version 2015.3.1104.1050

    I have the same code only with replaced dlls. 

    How to resolve this?

    Thank you in advance

    Hi Roshan,

    I tested your code but I wasn't able to reproduce the described behavior. Can you please take a look at the attached project and let me know if I am missing something?

    Do you need help with upgrading your AJAX, WPF or WinForms project? Check the Telerik API Analyzer and share your thoughts.
