Hi i have a problem, after executing  my key commands in the tree the tree navigation with the arrow keys stops working.If i click on any element with the mouse it works but after the execution it stops.The thee has focus the commands work if you use them more than once.
public void OnKeyDown(BehaviourArgs<KeyEventArgs> param)
        {
            RadTreeView tree = (((System.Windows.RoutedEventArgs)(param.Args)).OriginalSource) as RadTreeView;
            if (tree == null)
                tree = ((Telerik.Windows.Controls.RadTreeViewItem)(((System.Windows.RoutedEventArgs)(param.Args)).OriginalSource)).ParentTreeView;


            switch (param.Args.Key)
            {
                case (Key.V):
                    if ((Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
                    {
                        if (_userDefienedFieldsForCopy.Count > 0)
                        {
                            selectedItems = tree.SelectedItems;
                            this.Paste();
                            
                        
                        }


                    }
                    break;
                case (Key.C):
                    if ((Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
                    {
                        selectedItems = tree.SelectedItems;
                        this.Copy();
                      
                    
                     }

Hello,

Could you please check if the focus is inside the TreeView after the execution of your custom commands. TreeView has to have the focus in order to provide correct behavior for arrow key navigation.
If the focus is inside the TreeView, could you please provide us a sample project simulating the issue?
