I have a button on a form in a PCL-based iOS app which when clicked should display a pre-populated picker by giving it focus from the button click handler. It works sometimes but not always, is there a reason for this? I've used the same technique to display a datepicker and it works 100% of the time so I'm wondering why the picker is hit and miss? A forum search revealed a couple of related questions but not an answer/solution that was confirmed as working. Can anyone explain why I'm seeing this issue and/or offer a solution? Thanks.
