  I'm trying to enable tabs reordering, but it works only when items are set in xaml.
  
  This works:

  <t:RadTabControl AllowDragReorder="True" x:Name="radTabControl1">

      <t:RadTabItem Header="item1" />

      <t:RadTabItem Header="item2" />

      <t:RadTabItem Header="item3" />

  </t:RadTabControl>

  
  And this don't
  

  <t:RadTabControl AllowDragReorder="True" x:Name="radTabControl1" ItemsSource="{Binding list}" />

  
  
  How to make this work with binding?

  My code didn't work because I used List instead of ObservableCollection

  Hello Roman,
  
  Yes. I forgot to mention that ObservableCollection<> is very suitable in scenarios when you make changes both in the UI and in the ViewModel. ObservableCollection implements ICollectionChanged and IPropertyChanged interface and this way every change in the ViewModel is automatically reflected in the UI.

  The DLLs you included in this demo are version 2011.1.0315.40.
  I am currenting using version 2011.2.0920.35.
  
  RadTabControl reordering is not working for my current version through Data Binding on the ItemsSource. If I reference your version of DLLs, it works.
  
  Thanks,

  Hello Corey,

  We managed to reproduce this issue with the 920 (Q2 2011 SP) dlls. The good news is that this is already resolved and the fix will be included in the upcoming Q3 2011 Official Release.
  Please excuse us for the inconvenience caused.

  All the best,
