Recently we changed the build-in drag-drop manager of the RadTreeView
control. In the past it used the RadDragAndDropManager
, which is now obsolete. Currently you are allowed to choose which manager to use (the obsolete one or the currently supported one). This can be done by setting the telerik:TreeViewSettings.DragDropExecutionMode
attached property. If you set it to Legacy
you will use the obsolete manager, otherwise (setting it to New
) you will use the DragDropManager
. In the future we will delete the obsolete manager and the control will use the new one.
Please note that in order to use the new manager you will have to subscribe to the desired events and customize the drag-drop logic according to your scenario. You can do this using this code just after the InitializeComponent()
For more information about the DragDropManager
you can refer to this article
Furthermore, you can take a look at our online demonstration projects
and see how we use custom behaviors.
I hope this will work for you.
