If you prepare a Xamarin.Forms app to respect iOS Dark Mode, it is apparent that the RadDataForm is only respecting the native elements for Dark Mode.

REPRODUCIBLE

For example, use my attached reproducible.  Notice how the text in the native editors has the appropriate light text, but the background is still stuck on light coloring.

If you try to use Editor style or GroupHeaderStyle, you can't use DynamicResource because the style's properties are not BindableProperties:

We really need these properties to be usable with DynamicResource, so this is a feature request more than a bug report. Update the properties to BindableProperties that with with DynamicResource.

WORKAROUND

A workaround for this would be to set everything you can to be transparent:

Thank you.

Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource.

Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.

Currently, all groups are expanded by default. We should expose methods to collapse/expand certain groups. Furthermore, CollapseAll, ExpandAll groups should be considered as well.

Add localization for DisplayOptions data annotation.

The Source property should support two way binding.

Available in the R2 2018 release.

Expose a way to control the exact string visualized in the DecimalEditor. After entering 1234.2 in the editor, users should be able to configure the string to see 1,234.20.
Available in minor release 2017.2.0602. It will also be available in the R2 2017 SP release.
