  4. SfSchedule not displaying OnInitialized data

SfSchedule not displaying OnInitialized data

I'm using SfSchedule to display a List of ScheduleForm data, which is generated in OnInitialized method using previously loaded data from ScheduleService​. However, when the application is opened, the SfSchedule is loaded as empty. Even after the data is loaded, the SfSchedule doesn't display the data, even though the List<ScheduleForm> is correctly filled. Why doesn't SfSchedule work with data from OnInitialized method?

SfSchedule code:

@page "/schedule"

@using MyProject.Shared.Models

@inject IScheduleService ScheduleService

<SfSchedule TValue="ScheduleForm" SelectedDate="@(new DateTime(2021, 4, 12))" CurrentView="View.Week" FirstDayOfWeek="1">    

<ScheduleViews>       

<ScheduleView Option="View.Day" StartHour="07:00" EndHour="22:00"></ScheduleView>        

<ScheduleView Option="View.Week" StartHour="07:00" EndHour="22:00"></ScheduleView>   

</ScheduleViews>    

<ScheduleEventSettings DataSource="@schedules"></ScheduleEventSettings>

</SfSchedule>

@code:

@code {    

int number = 1;    
string course = "A";    
List<MyProject.Shared.Models.Schedule> schedulesData = new List<MyProject.Shared.Models.Schedule>();    
List<ScheduleForm> schedules = new List<ScheduleForm>();    

protected override async Task OnInitializedAsync()    
{        
await ScheduleService.LoadSchedules();        
schedulesData = ScheduleService.Schedules;        
int i = 0;        
foreach (var schedule in schedulesData)        
{            
foreach (var entry in schedule.Entries)            
{                
if (entry.Course == course && entry.Subject.Number == number)                
{                    
DateTime StartDate = new DateTime(schedule.Date.Year, schedule.Date.Month,                    schedule.Date.Day, entry.Start.Hour, entry.Start.Minute, 0);     
DateTime EndDate = new DateTime(schedule.Date.Year, schedule.Date.Month,                  schedule.Date.Day, entry.End.Hour, entry.End.Minute, 0);                    
schedules.Add(new ScheduleForm()                    
{                        
Id = i++,                       
StartTime = StartDate,                        
EndTime = EndDate,                        
Subject = entry.Subject.Value,                        
Description = entry.Description,                        
Location = entry.Location});                
}
}        
}
}    
public class ScheduleForm    
{        
public int Id { get; set; }        
public DateTime StartTime { get; set; }        
public DateTime EndTime { get; set; }        
public string Subject { get; set; }        
public string Description { get; set; }        
public string Location { get; set; }    
}
}

Hi Kristina, 

Greetings from Syncfusion Support. 

We could replicate the problem ‘appointment not displaying when defined in OnInitialized’ at our end and confirm this as defect. We have logged the bug report which can be tracked through the following link. 

The fix will be included in our Volume 2 SP release expected to be rolled out by mid of August, 2021. So we appreciate your patience until then.
