    Hello Bruce SeungWon,

    Please examine the attached solution and lee us know if it helps you or not. Using INotifypropertyChanged interface  and UpdataSourceTrigger=PropertyChanged works fine at our side. Let us know if we are missing something too.

    Kind regards,

    In this configuration, SelectedIndex is not working for me either:

    <telerik:RadTabControl x:Name="tabControl"
                                   ContentTemplateSelector="{StaticResource ContentSelector}"
                                   ItemTemplate="{StaticResource ItemTemplate}"
                                   ItemsSource="{Binding Source={StaticResource DataSource},
                                                         Path=Reports}"
                                   SelectedIndex="{Binding SelectedIndex,
                                                           UpdateSourceTrigger=PropertyChanged,
                                                           Mode=TwoWay}" />


    UPDATE: never mind... my mistake. I was assigning {StaticResource DataSource} at the RatTabControl level instead of at the window level.
