RecordsNavigationController for Blazor

This functionality is not supported because currently Blazor ListView cannot be used as an > order provider. You can enable the NextObject and PreviousObject actions by specifying > your own order provider - however, in this case, the order of records may be different > because of grouping, sorting, and filtering. Here is an example:

C#
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.SystemModule;

namespace MainDemo.Module.Blazor {
    public class EnableRecordsNavigationController : ViewController<DetailView> {
        public EnableRecordsNavigationController() {
            TargetViewNesting = Nesting.Root;
        }
        protected override void OnActivated() {
            base.OnActivated();
            Frame.GetController<RecordsNavigationController>().Active.RemoveItem> ("TemporaryNotSupported");
        }
    }
    public class BlazorRecordsNavigationController : RecordsNavigationController {
        protected override void OnActivated() {
            base.OnActivated();
            OrderProviderSource.OrderProvider = new StandaloneOrderProvider(ObjectSpace, > ObjectSpace.GetObjects(View.ObjectTypeInfo.Type));
            UpdateActionState();
        }
    }
}

Since this functionality depends on the grid control's data binding mechanism, we cannot > say when it will be available out of the box. We will definitely take your request into > account.
