    Hi,
    I have enabled the drag and drop feature in Rad Tree View, but it is causing some distortion in the view after an item is been dragged and dropped to the new position.
    Item is added to the new position but not been deleted from the orginal old position in the view.

    Please find the attached screen, to view the result what I'm getting after drag and drop.

    Please help me on this as soon as possible.

    Thanks in advance.

    Hello Manishkumar,

    The image attached looks pretty disturbing. However, we did not have received any reports about the issue described.
     Unfortunately, we are unable to reproduce it from our side. Is it possible to send sample application that illustrates the problem.

    Hi

       I am also facing the same kind of problems the code is as below. and the senario is

                1. bind an observablecollection<Item>  "Steps"  to the items source, each steps in collection have another property known as substeps of type observablecollection<Item>.
      
                2. select all the leafs of a node, drag and drop those in to another node. the u select the dragged item(source).


    <UserControl.Resources>
            <HierarchicalDataTemplate x:Key="Group" ItemsSource="{Binding SubSteps}">
                <ContentPresenter Content="{Binding Name}"/>
            </HierarchicalDataTemplate>
        </UserControl.Resources>
       
        <telerik:RadTreeView Name="radTreeView1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"  SelectionMode="Multiple"
                             IsDragDropEnabled="True" IsDropPreviewLineEnabled="True"
                             ItemsSource="{Binding Steps}" ItemTemplate="{StaticResource Group}" AllowDrop="False">

    Hello Manishkumar,

    You say that you are also facing the same kind of problems as originally reported. May I ask you to let me know the exact version that you use? Have you tried the latest assemblies?
