Hi,

We will consider introducing such events, in the meantime, there is a straight-forward approach to achieve your requirement by subscribing to the PropertyChanged event of the RadTabView and checking whether it is the SelectedItem that is affected. For example:

private void TabViewGettingStartedXaml_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
        {
            if (e.PropertyName == "SelectedItem")
            {
                Debug.WriteLine(((sender as RadTabView).SelectedItem as TabViewItem).HeaderText);
            }
        }

This should work for you.
