Why isnt Scheduler populated with appointments from my Mongodb server (using Mongoose)?

I am building a MEAN-application with Scheduler. Creating appointments and saving them to the mongodb database works flawlessly, hoewever, the schedulers remains empty while there are many appointments in the database. This is in my index.js

app.post("/GetData", (req, res) => {
Event.find({}, function(err, events) {

I see in my Network tab in my browsers developer tools that when the Scheduler is loaded, the 'getData returns a '200 OK' with the request
Running the 'GetData' endpoint in postman gives me these documents:

        "startTime""Tue Nov 12 2019 12:00:00 GMT+0100 (GMT+01:00)",
        "endTime""Tue Nov 12 2019 12:30:00 GMT+0100 (GMT+01:00)",

How does it come that I dont see the appointments in the scheduler?

private dataManager: DataManager = new DataManager({
url: 'http://localhost:8000/GetData',
crudUrl: 'http://localhost:8000/BatchData',
adaptor: new UrlAdaptor

this is what I have as dataManager

Hi Youssef, 
Syncfusion Greetings. 
We have tested your shared code in which field mapping is incorrect, which is the root cause of the reported issue. We prepared the sample below with the right field mapping, please refer to it.

Hi Yasser,

Greetings from Syncfusion support.

We have validated your query based on your shared images and in your DB the appointment start and end times are stored in the UTC format. By default, while assigning this data to the Scheduler it automatically converts the start and end times of the appointment based on the System timezone. Because of that, the Scheduler appointments are rendered in the 11.

Ex: If you are in the UTC +3 Moscow timezone. If the appointment start time is May 19, 2022, at 9 AM in UTC. The Schedule automatically adds three hours to the appointment start time-based on the System's local timezone UTC +3 Moscow. So, the appointment was rendered on May 19, 2022, at 11 AM.

If you want the Schedule to render the appointment at the exact time that is stored in the DB can you kindly share the below details?

  • Are you using the Timezone property of the Schedule?
  • If yes can you share the Timezone property value?

Refer to the below UG for more details about working with Schedule Timezone.

Please, I need help. I want to save in the database "idUser" to have each activity has a user who created.

I managed to create "idUser" in the database as you see.

==> Code "routes/activity"


==> database


Now I want to give the value of "id User", how i pass the value? knowing that I can recover the value and I don't know how to add it ?

==> Code "activity.component.ts"

Hi Yasser,

We have validated your query “I want to save in the database ‘idUser’” at our end. We suggest you add the IdUser field value to the added or changed appointment data on the actionComplete event of the Schedule as shown in the below code snippet. So, you can get the IdUser field value that will be available at the server end and you can store it in your DataBase.


export class AppComponent {

  public dataRecord<stringany>[] = extend([], zooEventsDatanulltrueas Record<stringany>[];

  public selectedDateDate = new Date(2021115);

  public eventSettingsEventSettingsModel = { dataSource: this.data };

  public currentViewView = 'Week';


  public onActionComplete(argsActionEventArgs): void {

    if (args.requestType === 'eventCreated') {

      // This block will execute once an appointment is created

      args.addedRecords[0].IdUser = 'User Id';


    else if (args.requestType === 'eventChanged') {

      // This block will execute once an appointment is edited

      args.changedRecords[0].IdUser = 'User Id';
