Hi Asser,

We have implemented the concept of alternate route in our application by using the approach, you suggested. Thanks for your kind support.

Thanks,

Hi Sandeep,

Actually the returned route results contain the Route and it is a Polyline Geometry. And the Barriers parameter is a type if Enumerable(Graphics) so you will add the returned line to the Barriers parameter then do another Route task with the new parameter. Then the returned results will be another polyline route. So now you have two possible routes. Then do the same using the two routes you got to create a third route. And then show each route on the map to show the user the three possible routes.

No user interaction needed in this to achieve that.

Thanks,

Asser

Thanks for your reply.....But my requirement is to achieve alternate route without human intervention....The example you gave shows adding barriers using point click on map.How can i consider the first route as barrier using code in silverlight..can you give some other example or can suggest the steps to achieve this?
