Coule you please so kind to share a grid demo for me, I change gridData at runtime in onSelect event, but can't make it work.
async void onSelect(Syncfusion.EJ2.Blazor.Lists.SelectEventArgs args)
{
var selectData = JsonConvert.DeserializeObject<Order>(args.Data.ToString());
var selectId = int.Parse(selectData.id);
var orderWithItems = await orderService.getOrderWithItems(selectId);
gridData = orderWithItems.items.ToList();
this.StateHasChanged();
this.detailgrid.DataBind();
this.detailgrid.Refresh();
}
