[iOS] DatePicker MaxYear property ignores month and day.

[takla21]

Current behavior

Only the year in DatePicker.MaxYear is used when limiting the max date on UIDatePicker.

Expected behavior

In previous version, the UIDatePicker used to block month and day as well.

How to reproduce it (as minimally and precisely as possible)

• Download this sample DatePickerMaxDateSample.zip
• Deploy on iOS
• Click on the datepicker
• Select any date in the future MaxYear = DateTimeOffset.Now

Workaround

Anything else we need to know?

@carldebilly isn't this expected ?

[carldebilly]

Yep. That's the expected result as it's exactly the behavior on Windows.

To have min/max dates, you'll need to use CalendarDatePicker/CalendarView: https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.calendardatepicker

CalendarDatePicker Class (Windows.UI.Xaml.Controls) - Windows UWP applications

Represents a control that allows a user to pick a date from a calendar display. Equivalent WinUI class: Microsoft.UI.Xaml.Controls.CalendarDatePicker.

@takla21 is this a regression from your end, or something you'd expect to work ?

[takla21]

@jeromelaban it's actually a regression for iOS. It used to work (blocking days and month) with the previous uno version we were using (3.1.29)

@carldebilly The thing is that it's does block days and month on android. I've updated the sample on android to the same version as android here DatePickerMaxDateSample.zip. So does it means that it's a bug on android?

[carldebilly]

Yep it's a bug :-).

It should be possible to set a feature flag to bring back the old behavior.

To be honest, the "native DatePicker" is a lot closer to CalendarDatePicker than DatePicker itself. I think they should come back as native pickers for CalendarDatePicker instead...
