Yes, the DateTime field needs to be visible to write back as I understand. The operator really doesn't need to see this and it takes up space. I was messing around with trying to get it behind the Done button and somehow may have gotten it behind the background or tab. It doesn't show up in the designer now, see desktop.jpg, but it does show up on the device in the front of Done button (see mobile.jpg).Hi Mark,
Can I ask why you would want to do this?
