Blazor Grid with Row Virtualization & CheckBox Selection: Column Reorder doesn't work

Hi SyncFusion,

I use Blazor Grid in Version (Blazor Server App) and a grid with Row Virtualization, Checkbox Selection and Column Reorder. But the Column Reorder doesn't work properly - the Headers can be changed, but the order of the corresponding values doesn't change.

I have checked following documentation:




My short example is:

@page "/test"

@using Syncfusion.EJ2.Blazor.Data
@using Syncfusion.EJ2.Blazor.Grids

<EjsGrid DataSource="@Orders" AllowReordering="true" AllowSelection="true" Height="550" Width="1550" EnableVirtualization="true">
  <GridSelectionSettings Type="SelectionType.Multiple"></GridSelectionSettings>
    <GridColumn Type="ColumnType.CheckBox" Width="50"></GridColumn>
    <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
    <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
    <GridColumn Field=@nameof(Order.OrderDate) HeaderText="Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
    <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>

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

  protected override void OnInitialized()
    Orders = Enumerable.Range(1, 75).Select(x => new Order()
      OrderID = 1000 + x,
          CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
            Freight = 2.1 * x,
            OrderDate = DateTime.Now.AddDays(-x),

  public class Order
    public int? OrderID { get; set; }
    public string CustomerID { get; set; }
    public DateTime? OrderDate { get; set; }
    public double? Freight { get; set; }

I hope, you can reproduce my problem.

Kind Regards
