Hi Keith Gemeinhart,
Thank you sir, i managed to get the elevation value from the thread you share. Just an issues that i need help that i can't rendered the map, i can't move the mouse the other part of map and the zoom function does not trigger. I just able to move the mouse cursor on the current view when the application start up. I put my sceneview in the same user control of my mapview, Is that the correct way to do that?
