Implemented Multiple selection mode which is consistent with the same mode in RadListBox, RadGridView, etc.

Multiple Selection refers to Selecting / Deselecting items with single Mouse click or single space key press.

Until Q3 2015 this Extended ans Multiple Selection had the same behavior.


Will be available in Q3 2015 Release.

Allow cancelling a drag operation originating from certain items - basically the customers need to disable the drag operation on some items.
====
Here is a possible solution with handling DragInitialize
 
DragDropManager.AddDragInitializeHandler(this.tree, this.OnDragInitialize, true);

 private void OnDragInit(object sender, DragInitializeEventArgs e)
        {
            if (((e.OriginalSource as RadTreeViewItem).Header == "B1")
            {
                e.Data = null;
                e.DragVisual = null;
            }

When you tab through your application you can observe that when the focus moves to the TreeView it will focus the first TreeViewItem. However, when you change the ItemsSource collection of the TreeView at run-time you won't be able to tab through the TreeView or its first TreeViewItem at all.

SelectedItems collection does not work correctly when the RadTreeView is virtualized and ContainerBindings (SL) / Style Bindings (WPF) are used for binding the IsSelected property.


The issue is not reproducible with R3 2016 version of RadTreeView with both Multiple and Extended Selection mode.
Please open a new support thread with detals from your scenario if you encounter similar issue.

Consider replacing the current touch gesture which starts drag operation. Now the gesture (tab and hold + move up) is not very intuitive. 

With Q2 2015 Release the DragDrop on touch device will work the following way. Hold down the finger on RadTreeViewItem, TouchIndicator circle appears and then you can move your finger to start the dragging.

If you define a RadMaskedInput control in the ItemEditTemplate of RadTreeView and then bind the Value property of the masked input to a property from the RadTreeViewItem's view model, the input displays the view model's class ToString() method. Instead the value of the bound property should be displayed.

Fix is available in LIB Version: 2015.3.1005.
