Hi Rakesh,
Syncfusion Greetings.
We can perform CRUD operations using DataManager and for the same we have prepared a sample with Rest API and UrlAdaptor
private dataManger: DataManager = new DataManager({
url: "http://localhost:9876/api/Url",
crossDomain: true,
adaptor: new UrlAdaptor()
});
Kindly refer below UG link.
By default, Scheduler renders the data based on the current view date range(Load on demand basis).
Kindly try the above sample and let us know, if you need further assistance on this.
Regards,
M.Vinitha devi
