In our application, we would like to change the mouse cursor whenever the user hover the mouse over a graphic. We've came up with a way to do it using the GraphicsLayer.HitTestAsync() method whenever the mouse move. But I am not sure if this is the best way to do it because as I move my mouse over the map, my CPU spikes to 10-15%. I think this is too costly in terms of performance for such a simple feature.
private async void MapView_MouseMove(object sender, MouseEventArgs e)
{
Graphic graphic = await HitTestAsync(_mapView, e.GetPosition(_mapView));
UpdateHoveringGraphic(graphic);
}
The UpdateHoveringGraphic() function will then determine if the graphic has changed to generate a MouseEnter and MouseLeave event.
We have several GraphicsLayer, so this adds up. Does anyone have any suggestions to accomplish this feature in a less resource intensive way?
Thanks.
