Hi,

I'm trying to load the appointments dynamically by listening to the DateChanged event and then load the appointments for the current view from the server. The problem is that the scheduler doesn't seem to react if the list assigned to Data changes. Also I cannot find any public "Refresh" method.

Any suggestions? My code is below

<Scheduler Data="@SchedulerItems"
           Date="@_schedulerDate"
           SelectedView="@_schedulerSelectedView"
           Editable="false"
           UseInternalEditing="false"
           Draggable="false"
           DateChanged="OnSchedulerDateChanged"
           SelectedViewChanged="OnSchedulerViewChanged"
           EditItemClicked="OnSchedulerItemClicked"
           ItemStyling="OnItemStyling">


private async Task OnSchedulerDateChanged(DateOnly newDate)
{
    _schedulerDate = newDate;    
    await LoadBookingsForScheduler();    
}

private async Task LoadBookingsForScheduler()
{
    var (from, to) = GetVisibleDateRange();
    var query = new GetBookingsOverviewQuery { From = from, To = to };
    var response = await Http.PostAsJsonAsync("api/bookings", query);

    if (response.IsSuccessStatusCode)
    {
        var dtos = await response.Content.ReadFromJsonAsync<List<BookingOverviewItemDto>>() ?? [];
        SchedulerItems = dtos.Select(SchedulerBookingItem.FromDto).ToList();
        _schedulerKey++;
    }
}
```</div>
