How to know which artem google map polygon are selected

Aug 26, 2011 at 12:37 PM


I am developing a ASP.NET web app in C#. In my pages I use a Artem Google Map Control inside a User Control embedded in Update Panel.
All is done in code behind (c#) , create the map, add polygons (from data in KML) and show it.
On the client side using javascript when a user clicks on a polygon it changes it color if it is selected or not.
My problem is that I need to know ( on Code Behind) which polygons are selected. ¿Can someone give a hint?
Thanks a lot
