IeditableObject on dataform

[Sami]

HI:

I read the documentation about cancel option, and all that I saw says that you should implement interface IEditableObject.  I have a project that doesn't implement it and cancel button works perfectly over observable collection against entity framework throw CollectionViewSource:

            ICollectionView c = CollectionViewSource.GetDefaultView(db.Clientes.FromSqlRaw("Select * From CLIENTES ").ToList());
            dbGrid.ItemsSource = c;
            dataForm.ItemsSource = c;

 

in other project with other table it doesnt work unless my object implments IEditableObject, ¿Why?

Is necesary implement IEditableObject incluiding if use EnityFramework over observable collection? Is necesary implment this IedtiableObject interfase also if I use RadEntityFrameworkCoreDataSource instead  ICollectionView ?

 

Thanks in advance for your dvise.

Hello Sami,

The Cancel option of the RadDataForm control would require the items of the data source to implement either the IEditableObject or the INotifyPropertyChanged interfaces. My guess is that since the Cancel option works without having implemented the IEditableObject interface, is that the INotifyPropertyChanged interface is implemented instead. Or the class, which represents the items of the data source derives from a class that implements the INotifyPropertyChanged or IEditableObject interfaces.

I am not sure that I understand the question regarding the RadEntityFrameworkCoreDataSource class and the ICollectionView interface.

With this being said, would it be possible to double-check if this is the reason in on your end?
