Kanban refresh not work when triggered by SignalR

[Maurizio Meloni]

Hello all, in my blazor server application i use the SignalR for update dinamically the razor pages of my app.

 When i create a component on a page wich i show on a syncfusion kanban component in another page, i call the SignalR method. 

In the page with the Kanban Component i connect to the SignalR connection and each time i raise a specific method, the page should update.It seems to work for everything but the kamban component (it not refresh)

 Here i save the component

public async Task<IDataResult<Ticket>> SaveTicketAsync(Ticket ticket)
       {
           var result = await _ticketRepository.AddAsync(ticket);
           if (result.Success)
           {
               ticket.Id = result.GetData().Id;
               await _hubContext.Clients.All.RefreshGenericTickets();
               return new GoodDataResult<Ticket>(ticket);
           }
 
           return new BadDataResult<Ticket>(result.ConcatenatedErrorMessages);
 
       }

here is my blazor component

SfKanban<KanBanTicket> KanbanBoard;

protected async override Task OnInitializedAsync()
  {
      var result = await _viewModel.LoadUIData();
      if (!result.Success)
      {
        
            ErrorMessage = result.ConcatenatedErrorMessages;
      }
      MyDatasource = _viewModel.KanbanTickets;
 
 
      var hubConnection = new HubConnectionBuilder()
         .WithUrl(_navigation.ToAbsoluteUri("/SignalRHub"))
         .Build();
 
      hubConnection.On("RefreshGenericTickets", async () =>
      {
      
          await InvokeAsync(async () => {
 
              MyDatasource = null;  
              
              //reload data when signalr receive the "refreshGenericTickets" method
              await _viewModel.LoadUIData();
              
              MyDatasource = _viewModel.KanbanTickets;
              await KanbanBoard.RefreshAsync();
              ErrorMessage = "test";
              this.StateHasChanged();
          }
          
          );
      });
 
      await hubConnection.StartAsync();
 
  }

<SfKanban CssClass="kanban-overview" @ref="KanbanBoard" TValue="KanBanTicket" KeyField="State" @bind-DataSource="MyDatasource" ID="kanbanTicket" Height="70vh" AllowDragAndDrop="false">
    <KanbanColumns>
 
        @foreach (Syncfusion.Blazor.Kanban.ColumnModel item in columnData)
        {
            <KanbanColumn HeaderText="@item.HeaderText" KeyField="@item.KeyField" AllowToggle="@item.AllowToggle">
                <Template>
                    @{
                        KanbanColumn column = (KanbanColumn)context;
                        <div class="header-template-wrap">
                            <div class="header-icon e-icons @column.KeyField[0]"></div>
                            <div class="header-text">@column.HeaderText</div>
                        </div>
                    }
                </Template>
            </KanbanColumn>
        }
    </KanbanColumns>
    <KanbanDialogSettings>
        <Template>
            @{
                KanBanTicket data = (KanBanTicket)context;
 
            }
            @data.DateCreation.ToString()
        </Template>
    </KanbanDialogSettings>
    <KanbanCardSettings HeaderField="Title" ContentField="DisplayType" GrabberField="Color">
        <Template>
            @{
                KanBanTicket data = (KanBanTicket)context;
                   <CoverTicketBacklogDetail Data="data"/>
            }
        </Template>
    </KanbanCardSettings>
    <KanbanEvents TValue="KanBanTicket" CardClick="@OnCardSingleClick" CardDoubleClick="OnCardSingleClick" DialogOpen="@OnDialogOpen"></KanbanEvents>
</SfKanban>    
     <GenericTicketDialog @ref="selectedTicketDialog"/>
 
}
<p>@ErrorMessage</p>
