Ajax Binding

Updated on Oct 27, 2026

You can configure the Scheduler for Ajax binding to load event data remotely and send CRUD operations to server endpoints. This approach is useful when the event data is stored on the server instead of in the page.

For a complete example, refer to the demo on binding the Scheduler to remote data.

Razor

    @(Html.Kendo().Scheduler<Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel>()
        .Name("scheduler")
        .Date(new DateTime(2013, 6, 13))
        .StartTime(new DateTime(2013, 6, 13, 7, 00, 00))
        .Height(600)
        .Views(views =>
        {
            views.DayView();
            views.WeekView(weekView => weekView.Selected(true));
            views.TimelineView();
        })
        .Timezone("Etc/UTC")
        .DataSource(d => d
            .Model(m =>
            {
                m.Id(f => f.TaskID);
                m.RecurrenceId(f => f.RecurrenceID);
                m.Field(f => f.Title).DefaultValue("No title");
                m.Field(f => f.OwnerID).DefaultValue(1);
            })
            .Read("Read", "Scheduler")
            .Create("Create", "Scheduler")
            .Destroy("Destroy", "Scheduler")
            .Update("Update", "Scheduler")
        )
    )

C#

    public class SchedulerController : Controller
    {
        private ISchedulerEventService<TaskViewModel> taskService;

        public SchedulerController(
            ISchedulerEventService<TaskViewModel> schedulerTaskService)
        {
            taskService = schedulerTaskService;
        }

        public IActionResult Index()
        {
            return View();
        }

        public virtual JsonResult Read([DataSourceRequest] DataSourceRequest request)
        {
            return Json(taskService.GetAll().ToDataSourceResult(request));
        }

        public virtual JsonResult Destroy([DataSourceRequest] DataSourceRequest request, TaskViewModel task)
        {
            if (ModelState.IsValid)
            {
                taskService.Delete(task, ModelState);
            }

            return Json(new[] { task }.ToDataSourceResult(request, ModelState));
        }

        public virtual JsonResult Create([DataSourceRequest] DataSourceRequest request, TaskViewModel task)
        {
            if (ModelState.IsValid)
            {
                taskService.Insert(task, ModelState);
            }

            return Json(new[] { task }.ToDataSourceResult(request, ModelState));
        }

        public virtual JsonResult Update([DataSourceRequest] DataSourceRequest request, TaskViewModel task)
        {
            //example custom validation:
            if (task.Start.Hour < 8 || task.Start.Hour > 22)
            {
                ModelState.AddModelError("start", "Start date must be in working hours (8h - 22h)");
            }

            if (ModelState.IsValid)
            {
                taskService.Update(task, ModelState);
            }

            return Json(new[] { task }.ToDataSourceResult(request, ModelState));
        }
    }
