    @code {
        NorthwindContext Northwind { get; set; }
        List<Product> Products { get; set; }
        List<Category> Categories { get; set; }
    
        protected override async Task OnInitializedAsync() {
            Northwind = NorthwindContextFactory.CreateDbContext();
            Products = await Northwind.Products.ToListAsync();
            Categories = await Northwind.Categories.ToListAsync();
        }
    
        public void Dispose() {
            Northwind?.Dispose();
        }
    }
    

    To show or hide the editor’s drop-down button at runtime, use the IDropDownEditSettings.ShowDropDownButton property.
