<SfGrid DataSource="@Orders" />

    public List<Order> Orders { get; set; }

    protected override void OnInitialized()
        Orders = Enumerable.Range(1, 5).Select(x => new Order()
            OrderID = 0 + x,
            CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],

    public class Order
        public int? OrderID { get; set; }
        public string CustomerID { get; set; }
