  I have opened a bug on bugzilla for "focus" on Date and Time Picker some days ago

  With Buttons, picker.Focus works fine (for me).
  With Label + TapGestures, it does not work fine...

  Actually I was trying to use a Label and TapGesture myself (not a Button, my mistake) so I was experiencing the same issues as you, I guess. I have now changed it to a button (made to look like a Label) and it's working great! Thanks for your reply.

  Do make sure you're on main thread

  I had similar issues where timepicker is not showing up after DisplayAlert, I fixed by doing:

  Device.BeginInvokeOnMainThread (() => {
  yourPicker.Focus ();
  });

  It does not work for me either in a UWP and Windows 8.1 app. I haven't tested on any physical phones or emulators yet though. I'm using Xamarin.Forms 2.3.4-pre1. I filed a bug for this problem at https://bugzilla.xamarin.com/show_bug.cgi?id=52266

  This worked for me on IOS. Thanks a ton!! So many little quirks and bugs, very frustrating to get past them.

  Wow, thanx man... saved my life...

  Device.BeginInvokeOnMainThread (() => {
  yourPicker.Focus ();
  });

  This is similar to WPF

  Device.BeginInvokeOnMainThread(() =>
  {
  if (yourPicker.IsFocused)
  yourPicker.Unfocus();

  yourPicker.Focus();
  

  });

  Thanks ....
