    xamDockManager provides that functionality for the document tab groups within its DocumentContentHost (analogous to VS' tabbed documents) but this isn't something directly provided by the xamTabControl. You could probably put a Menu in the PostTabItemContent area that creates a menu item for each item in the tab control. e.g.

            <igWindows:XamTabControl x:Name="tabControl">
                <igWindows:XamTabControl.PostTabItemContent>
                    <Menu>
                        <MenuItem Header="V" 
                                  Click="MenuItem_Click"
                                  ItemsSource="{Binding Path=Items, RelativeSource={RelativeSource AncestorType={x:Type igWindows:XamTabControl}}}">
                            <MenuItem.ItemContainerStyle>
                                <Style TargetType="{x:Type MenuItem}">
                                    <!-- You could use a setter to set the command that you would use to select the tab -->
                                    <Setter Property="CommandTarget" Value="{Binding}" />
                                    <Setter Property="Header" Value="{Binding Path=Header}" />
                                </Style>
                            </MenuItem.ItemContainerStyle>
                        </MenuItem>
                    </Menu>
                </igWindows:XamTabControl.PostTabItemContent>
                <igWindows:TabItemEx Header="One">
                    <Button Content="Button 1" />
                </igWindows:TabItemEx>
                <igWindows:TabItemEx Header="Two">
                    <Button Content="Button 2" />
                </igWindows:TabItemEx>
            </igWindows:XamTabControl>
         
            private void MenuItem_Click(object sender, RoutedEventArgs e)
            {
                MenuItem clickedItem = e.OriginalSource as MenuItem;
     
                if (null != clickedItem && null != clickedItem.CommandTarget)
                {
                    // if you're binding the itemssource or not using tab items then
                    // you'll probably need to go through the tab control's 
                    // ItemContainerGenerator to get the index and set that as the selected
                    // index on the tab control.
                    TabItem ti = clickedItem.CommandTarget as TabItem;
     
                    if (null != ti)
                        ti.IsSelected = true;
                }
            }
