When a checked item is loading on demand its check state is lost.
This issue is applicable for both WPF and Silverlight.
And the issue is present always (no matter if the RadTreeView is databound, virtualized, etc).

Edit: Please use the approach from this help article if you need checkboxes in the RadTreeView.

We select a RadTreeViewItem by setting its property IsSelected to "True".
As a result, first "SelectionChanged" event is fired and second  - "Selected" event is fired.
If the selection is made "normally", by selecting an Item (with the keyboard or the mouse), the above events are fired in reversed order - first the "Selected" event and second the "SelectionChanged" evnet.

Tree is Virtualized and bind to colelction of DataItems.
On a button click, we add new Dataitem with IsInEditMode = true (bound to IsInEditMode of the RadTreeViewItem).
The new Item is in edit mode but the textBox in the ItemEditTemplate has no DataContext so no actual editing  can be performed.

Scenario casn be solved with adding the item, then switch its editmode in dispatcher:
DataItem item = new DataItem() { Name = "Item Editable" };
             
            (this.tree.ItemsSource as ObservableCollection<DataItem>).Insert(0, item);

            Dispatcher.BeginInvoke(new Action(() =>
            {
                item.IsInEditMode = true;
            }), DispatcherPriority.Loaded);

If virtualization is enabled, the RadTreeView resets the IsExpanded state of the root items to 'false' upon binding when child items are created.

When usgin PageDown key the final offset is different when using the End key. More over, the scroll event is fired several times when using the end key (3 in my case). Attached project reproduces the problem.

When the RadTreeViewItem (or the RadTreeView) is disabled and after a delay is enabled again it should go in "Normal" state. Now the control preserves its state, hence you are able to send more than one RadTreeViewItem in "Hovered" state.

The fix will be included in Q2 2015 SP.

The TreeView doesn't update the TriState of the parent item when an item is dragged and dropped.

In databound scenario the built-in checkbox and the tri-state mode are considered not supported and users are prompted to use checkbox in itemtemplate with 3state logic in the viewmodels.

1. End key does not work correctly when margin is set in the DataTemplate. Actually there is a small missmatch between the real "End" position and the one displayed by the tree.
2. When the IsAsynch property is used inside the binding of the ItemsSource property the End key does not work at all.

We have a RadTreeView with "Visibility" property set to "Hidden".
We add dynamically RadTreeViewItems to the RadTreeView.
If we change the "Visibility" to "Visible" - the RadTreeView is NOT displayed.

Originally this item is logged for scenario with XBAP. Currently we are unable to reproduce such issue with WPF 4.0 and latest version of our controls.
Please open a new support thread if you encounter similar issues at your side.

When a checked item is programatically removed from the RadTreeView.Items collection, it isn't removed from the CheckedItems collection.

Edit: Please avoid using this collection because it has never been implemented completely in RadTreeView. In DataBinding scenarios, you can use CheckBox in the ItemTemplate of the RadTreeView. Approach can be found here =>
http://docs.telerik.com/devtools/wpf/controls/radtreeview/how-to/howto-tri-state-mvvm.html 
CheckedItems colelction can be implemented in the ViewModels, instead of using the built-in property.

There should be a way to exclude the partially checked items from the CheckedItems collection. 
A a property can be added to specify whether they will be included.

TreeView: When the header of an Item is set to a TextBox, the selection of a RadTreeViewItem is incorrect

The original reported issue is that the following style does not work as expected.
<Style TargetType="telerik:RadTreeViewItem">
<Style.Triggers>
<Trigger Property="IsKeyboardFocusWithin" Value="True">
<Setter Property="IsSelected" Value="True" />
<Setter Property="Tag" Value="Selected" />
</Trigger>
<Trigger Property="IsKeyboardFocusWithin" Value="False">
<Setter Property="IsSelected" Value="False" />
<Setter Property="Tag" Value="Unselected" />
</Trigger>
</Style.Triggers>
</Style>

This is not supported by the RadTreeView Selection logic. Once the trigger applies with Selected / True, the IsSelected property is Locally set via the selector's code. This means future work of the trigger will not be successful over the IsSelected Property.

When TreeView is databound to RadObservableCollection and Suspen/Resume Notifications are used when removing items the Selected items collection contains empty object at the end after deleting item and selecting another one.

As a workaround you can use ObservableCollection.

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.
