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.
