    <DxScheduler @bind-StartDate="@StartDate" DataStorage="@DataStorage" CssClass="demo-sc-size">
            <DxSchedulerDayView DayCount="5" ShowWorkTimeOnly="true">
                    <div style="display: flex;">
                        <div class="dxbl-sc-date-hr-wrapper" style="width: 100%;">
                            <span class="dxbl-sc-date-hr-day">@context.Interval.Start.Day</span>
                            <span class="dxbl-sc-date-hr-week">@context.Interval.Start.ToString("ddd")</span>
                            string cloudCover = GetCloudCoverByDate(context.Interval.Start);
                            if(!string.IsNullOrEmpty(cloudCover)) {
                                <span class="@string.Format("scheduler-cloud-cover-icon {0}", cloudCover)"></span>

@code {
    DateTime StartDate { get; set; } = DateTime.Today;

    DxSchedulerDataStorage DataStorage = new DxSchedulerDataStorage() {
        AppointmentsSource = AppointmentCollection.GetAppointments(),
        AppointmentMappings = new DxSchedulerAppointmentMappings() {

            LabelId = "Label",
            StatusId = "Status",
            RecurrenceInfo = "Recurrence"

    string GetCloudCoverByDate(DateTime date) {
        foreach(WeatherForecast item in ForecastService.GetForecast())
            if(date.Day == item.Date.Day)
                return GetCloudCoverCssClass(item.CloudCover);
        return string.Empty;
