When a child item from a RadTreeView is selected and then the selection is changed to any of the parents of this item, the FocusVisual (the dotted border) stays on the child item.


Available in LIB version: 2016.1.21

When we drag and drop an Item of the RadTreeView out of the tree, the VisualState of the item stays mouse over.
Even if we click or drag other items, the only way to reset the VisualState of the item is to mouse over it. 
This can be observed in Silverlight's  Theming demo. 
===============

Resolution: The issue can be easily solved by setting telerik:TreeViewSettings.DragDropExecutionMode="New". This will be the default setting in future releases.

ArgumentException is thrown when TreeView becomes visible on a touch device

Users often need to customize only the Content of the TreeViewDragVisual.

The built-in logic for displaying Drop Target Template  (Drop Inside X, Drop after Y) is well accepted. However, there is no easy way to customize the Content of the DragVisual only , preserving the built in logic. If you create entirely new DragVisual much more code is needed to set up all scenarios.

Will be available in Q2 2015 Release.

Subscribing for the touch event ahndling in OnApplyTemplate might cause mermmory leaks or misfunction. Example - TreeView is first RadTabItem of TabControl. After several tabs pressing, the touch will not work - it is unregistered on Unloaded but it is not registered second time because OnApplyTemplate does not fire second time.
