Hi,
I'm happily using Graphic.IsSelected to visualize a selected graphic.
I've also using GeoView.SelectionProperties to change the color of the selection to DarkMagenta.
It looks like this:

Depending on the BaseMap though the size of the selection "glow" is too small to be seen (especially on a mobile device in the sunlight):

According this old post it is not possible to change the selection symbol. Maybe it is now? Or, as mentioned in the subject, I can change the size of the glow somehow.
Thanks
Soko
