Get each polygon Id!

Question asked by ilyass on Dec 15, 2014
Latest reply on Jan 18, 2015 by ilyass

Dear All,

 

I create a prototype which add a group of point to the map and create the drive time polygon around each point (Based on service area sample). The prototype is creating the polygons in the same time but i cannot control each polygon separately, i would like to create an Id for each polygon created around each point so i can use them for other query like polygon intersect ...

 

Below the code i create if anyone can help i will be grateful:
