Good affternoon,

I'm developing a locations simulator for windows phone 8 in XAML/C# and i have a little problem.

Once i iniciate the map i draw a couple of ATMs icons in a 10km radius of my current position.

But what i want, additionally, is: when i'm scrolling the map, i want to clear the the design and design new ATMs icons but in 10km radius of the center of the map, and so on...

Can anyone tell me what event i can use to perform this?
I've tried CenterChanged but won't work. View_Changed also don't work.

Thanks in advance
