Resource.ID does not contain buttons I placed in axml file.

below is my axml layout code <?xml version="1.0" encoding="utf-8"?>

In .cs file, I'm not getting buttons & radio button control's id to fetch it from it's view. When I try to use Resource.Id.btnNewRide....IDE not able to find it in Resource.Id

See attached image..all controls with red line.

Thanks
