Setting the HeaderStringFormat of RadTreeViewItem does not format the Header.

As a workaround, HeaderTemplate of RadTreeViewItem could be set which has TextBlock with StringFormat property set on its Text Binding.



 <DataTemplate x:Key="template">
                <TextBlock Text="{Binding ., StringFormat='Received ({0:N0})'}" />
</DataTemplate>

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.

TreeView is in TabItem of TabControl with IsContentPreserved = False. On ContextMenu open and when working with Contextmenu, the underlying RadTreeViewItem is in MouseOverState. Changing tabs then back to the tab with the TreeView. When working with contextmenu, the underlying treeviewitem is not is mouseoverstate. Could be reproduced in CustomContextMenu QSF sample. Not reproducible in AddRemoveDisable sample.
The workaround is to set IsContentPreserved to true on the RadTabControl.

Create localization resources for the DropActionText in the TreeViewDragVisual element. The localization resources should work as the TextDropAfter, TextDropBefore, TextDropIn and TextDropRoot properties used to work in the Legacy mode of the RadTreeView DragDrop.

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.

If an item that has multiple parents is about to be edited, the PreviewEditStarted event handler is fired so many times as the number of the item's parents. In this case setting the e.Handled property to True doesn't work as expected. 


Will be available in R2 2016 Release.

When the data is bound to the RadTreeView the AutoScrollToSelectedItem doesn't work. The same behavior appears when the RadTreeViewItems are created declarative and the SelectedItem is set True on any of its root level items.

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.
