Unfortunately no event is driven when the RouteIndex is changed by selecting a new route in the directions panel.
I raised the issue a while back http://code.google.com/p/gmaps-api-issues/issues/detail?id=3565

then how can i figure out the index any other way ??

[MymsMan]

You could possibly use a setTimeout loop to poll for  the current value every second an see if it has changed but it would be a bit ugly.

Thanks MymsMan for ur reply but what i want is user will select any route from suggested route and will click on the save button so that i can save the route index in my database.

[MymsMan]

If the user is clicking a Save button then you can just retrieve the current value from the Directions renderer object - Rend.getRouteIndex().

What is missing from the API is a notification of when the user selects an alternative route.
