[Zdenek]

Hi, when I try to Cancel a row creation i Grid's modal edit dialog - add action (either by clickin Cancel or just by closing the dialog) and there's no row selected in the grid, I get this exception:

warn: Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer[100]

This isn't the case, if a row in the Grid is selected.

Grid:

<SfGrid DataSource="@Orders" Toolbar="@(new List<string>() { "Add", "Edit", "Delete" })">

    <GridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true"

                      Mode="EditMode.Dialog" ShowDeleteConfirmDialog="true">

    </GridEditSettings>

</SfGrid>

@code {

    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)],

            }).ToList();

    }

    public class Order

    {

        public int? OrderID { get; set; }

        public string CustomerID { get; set; }

    }

}
