Allow buttons to be right aligned in the toolbar

Available in Q3 2014.

Loading a document that contains big images could lead to OutOfMemory exception.

Too many TreeViewItems are created internally when using virtualization. This causes the tree to consume large amount of space when performing virtualization intensive tasks like CollapseAll or ExpandAll.

The XAML team recently reviewed this issue and will not be addressing it.
On ExpandALL / CollapseALL virtualization creates / recycles / reuses containers - RadTreeViewItems. You cannot be sure when the GarbageCollector will free up the currently unused containers.
Also after even number of invocations (ExpandAll + CollapseAll), the containers that are not freed up from memory is not increasing - it is constant which means there is no memory leak to worry for.

When two equal objects are used in the source collection, the first is always selected when you try to select the others.

Workaround when TreeView is not databound.

Instead of adding objects directly in the TreeView's Items Collection, add RadTreeViewItems.
For Example, instead of
 treeView.Items.Add(1), 
treeView.Items.Add(2)

do

 treeView.Items.Add(new RadTreeViewItem(){Header = 1}, 
 treeView.Items.Add(new RadTreeViewItem(){Header = 2}

Workaround when TreeView is databound.

For example , if we databind the treeview to collection of DataItems and some dataitem is located in multiple places in the source collection.
Solution => Wrap the DataItem class in new class - DataItemWrapper. It can hold the underlying DataItem, add additional property  (for exampel ID) and override the Equals and GetHashCode methods.
This way different DataItemWrapper objects can hold equal DataItem objects. In such way if you bind the treeview to collection of DataItemWrappers the selection will be successful.

DECLINED:
The XAML team recently reviewed this bug  and won't be adressing it in future. It can be actually considered as feature request because selection should have notion for selected containers.
Unfortunately, the initial code design of the RadTreeView does not have such notion and the complexity of adding such feature now is very big.

When an Item is selected, the SearchText property should be updated so it shows the item's text. At the moment it stays with the last entered text. The scenario is valid only for Single mode

Place a RadComboBox control in a RadPane. Make it floating and dock it again. When selection is changed, the SelectionChanged event is fired multiple times.

Ability to export a diagram to PDF.

SelectedItems collection not updated when items are removed

On start up a Binding error is thrown in the Output for ElementName=WatermarkTextBox.

Available in LIB version 2016.3.1017, it will be also available in the 2016 R3 SP1 release. 

Now if you add a content to the panelbar the content inside will receive tab navigation only once due to the items control nature of the control.

The XAML team has recently reviewed the status of this issue and won't be addressing it in future releases.
In order to make the content (items) of a specific RadPanelBarItem (X)  focusable with tabKey, set TabNavigation="Local" on X.

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 users to resize the tiles. Possibly by dragging a left-mouse cursor on the edges of the tiles. This will give flexiblity beyond the 3 fixed size of minimized, maximized, and restored.

Prism View is incorrectly initialized when associated with a region

We have created a SDK sample with a CustomRegionAdapter for the RadTabControl and its implementation can be found in out SDK repository(https://github.com/telerik/xaml-sdk/tree/master/TabControl/PRISM/CustomTabControlRegionAdapter)

DropDownButton is leaking.

Currently, caret continues to blink even when typing or navigation is in progress (e.g. arrow key is pressed and held), which is inconvenient for the end users. Instead, the caret should stop blinking during these operations, similarly to industry standard apps like MS Word and OpenOffice.
