    I have databound RadTreeViewItem.IsExpanded in my item container style, but when the item is created, it ignores the binding (which is set to true) and sets the property to false.  I found another thread in the forum describing the same behavior happening with the IsChecked property.

    Call stack:

      Telerik.Windows.Controls.Navigation.dll!Telerik.Windows.Controls.RadTreeViewItem.IsExpanded.set(bool value) Line 390 C#
    > Telerik.Windows.Controls.Navigation.dll!Telerik.Windows.Controls.RadTreeViewItem.OnIsExpandedChanged(bool oldValue, bool newValue) Line 1186 C#
      Telerik.Windows.Controls.Navigation.dll!Telerik.Windows.Controls.RadTreeView.RestoreContainerProperties(object item, Telerik.Windows.Controls.RadTreeViewItem treeViewItem) Line 678 C#

    Hello Brian,

    I tried to reproduce the reported behavior on our side with our latest official release and it seems that the code works as expected. Could you please take a look at the attached project and let us know if there is something that I missed? It will be great if you can change the code so that the issue can be reproduced on our side and send it over. By doing this we will be able to further investigate the possible reasons behind.
