  Hi,
  
  i change the Focus in the radTreeView1_NodeCheckedChanged event.
  
  If i do this, the radTreeView1 dont remove the Highligh from the previous node. If i mouse over the previouse node, the Highlight is gone.
  
  Can i reset the RadTreeView Highlights in code?

  Hi Daniel,
  
  You have to set the SelectedNode property to null.

  Hi,
  
  i need the SelectedNode property but not the Highlight. I think it is a little Bug. The SelectedNode hase a bit darker Color than the Highlight Node.
  
  It confuse the User, he think 3 Nodes are selected but it is still only 1 Node selected the other tow one are only Highlighted.
  
  The Highlight Bug comes only, if the RadTreeView Control leaves the Focus in the NodeCheckedChanged event.

  Hi Daniel,
  
  I am afraid that I was not able to reproduce the issue. I set up a form with a RadTreeView and a RadButton. In the NodeCheckedChanged event I call RadButton.Focus() to remove the focus from the tree view and everything works as expected. Please provide more details on your application or submit a support ticket with a sample application which demonstrates the issue.

  Hi!
  I have a similar behavior of the RadTreeListView control in silverlight. This happened after upgrading to version 2011.3.1222
  If I change the selected node - the previous node is highlight a cell border
  
   <telerik:RadTreeListView x:Name="ComponentHierarchy"
                           AutoLoadHierarchy="True"
                           AutoGenerateColumns="False"
                           SelectionMode="Single"
                           SelectionUnit="FullRow"
                           ItemsSource="{Binding HierarchicalItems, Mode=OneWay}"
                           HorizontalAlignment="Left"
                           Visibility="{Binding HasError, Converter={StaticResource ...}, ConverterParameter=Inverse}"
                           RowIndicatorVisibility="Collapsed"
                           IsReadOnly="True" RowDetailsTemplateSelector="{StaticResource ...}"
                           IsDragDropEnabled="True"  
                           DragCueItemTemplate ="{StaticResource ...}">
      ...

  Hi Roman,
  
  This forum concerns RadControls for WinForms suite, rather than RadControls for Silverlight controls. Please address your question in the appropriate forums (http://www.telerik.com/community/forums/silverlight/treelist.aspx), so it can be handled by the appropriate staff members.
  
  Thank you for your understanding.
   
  Kind regards,
  Stefan
