In Xamarin.Forms, there is no multiline text box editor in RadDataForm.
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.
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.
With the current implementation in Xamarin.Forms, the control has no built-in support for enumerable properties. The approach is to create custom renderers and use the native editors. We need to expose default editors for enumerable and custom types.
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.
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.
We need to simplify the way the editors can be customized. XAML only solution would be great.
There is an empty group title view above the editors even if there are no groups. The red area on the attached screenshot.
If the following data annotations are defined: [DisplayValueFormat(Date = "MM-dd-yyyy HH:MM tt")] [ReadOnly] DisplayValueFormat is not applied properly.
When DisplayValueFormat is set to an Integer property, Zero value is not applied.
