Make a WPF Scroll Viewer scroll regardless of mouse position

I have a WPF application that has a tool bar then a content control that nests a grid that contains a Tabcontrol and a ScrollViewer that wraps a TabPanel.

The scrollviewer works great, but only if my mouse is hovering over the tab control. How can I get the scroll viewer to scroll as long as my cursor is in the window?

Try to capture the event in the Window and raise it in the TabControl, something around this (untested):

private void Window_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
    if (!e.Handled)
    {       
        e.Handled = true;
        var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);
        eventArg.RoutedEvent = MouseWheelEvent;
        eventArg.Source = sender;
        MyTabControl.RaiseEvent(eventArg);
    }
}
