The error message is not showing when the editor is empty and the ValidateAll method is called 

Allow multiple selection from the AutoCompleteEditor using Tokens and properly commit it.

Add TextAttributes option to DataFormEditorStyle and DataFormGroupHeaderStyle (e.g. Bold).

Add FontFamily option to DataFormEditorStyle and DataFormGroupHeaderStyle.

Expose an IsEnabled property for editors that can be toggled after DataForm is rendered.

Currently, only Data Annotations can determine whether or not a property's editor is read-only. If a specific editor's read only state needs to be changed dynamically (e.g. due to a selection in another editor), you would need to completely reload the DataForm.

Available in minor release 2018.2.727.250. It will also be available in the R3 2018 release.

The expected behavior when updating the text on a button click, for example,  is to expand the editor.

Currently the editor is expanded when the user starts typing inside it.

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.

The segmented editor does not change the underlying property immediately.

This prevents content below the control to be visible.

Available in the R2 2018 release.

Available in the R2 2018 release.

If the following data annotations are defined:

[DisplayValueFormat(Date = "MM-dd-yyyy HH:MM tt")]
[ReadOnly]

DisplayValueFormat is not applied properly.

Available in the 2018 R2 SP release.

Currently, on Android and UWP the date and time editors display popups with "OK" and "Cancel" buttons, so one can easily dismiss the control even if a value has been selected. This will still keep the null value in the dataform. On iOS value changes are propagated immediately to the dataform, so there is no way to keep the null value.

When DisplayValueFormat is set to an Integer property, Zero value is not applied.
