Scheduler - Lazy loading data on

[Sam]

We have implemented a scheduler on an mvc page:

01.@(Html.Kendo().Scheduler<SchedulerBasicCore.Models.ScheduleViewModel>()
02.    .Name("scheduler")
03.    .Date(DateTime.UtcNow)
04.    .Editable(false)
05.    .Height(600)
06.    .Toolbar(t => t.Pdf())
07.    .AutoBind(true)
08.    .Views(views =>
09.    {
10.        views.DayView();
11.        views.WeekView(weekView => weekView.Selected(true));
12.        views.MonthView();
13.        views.AgendaView();
14.    })
15.    .Timezone("Etc/UTC")
16.    .DataSource(d => d
17.    .WebApi()
18.    .Model(m =>
19.    {
20.         m.Id(f => f.EventId);
21.         m.Field(f => f.Title).DefaultValue("No title");
22.    })
23.    .Read(read => read.Action("Schedules_Read", "Scheduler").Data("getAdditionalData"))
24.     )
25.)
26.
27.<script>
28.    function getAdditionalData() {
29.        var scheduler = $("#scheduler").data("kendoScheduler");
30.
31.        var result = {
32.            start: scheduler.view().startDate().toISOString(),
33.            end: scheduler.view().endDate().toISOString()
34.        }
35.
36.        return result;
37.    }
38.</script>

 

 

This calls through to an API and this all work successfully.

 

However, as i scroll through weeks or different views the api is called until some data is successfully returned. Once data is successfully returned no further changes of the views or scrolling through the dates result in an api call.

 

So I am wondering what I need to do to support loading data per view or date change?

 

Thanks

Hello Sam,

There is an existing example for ASP.NET MVC, where loading appropriate resources based on the navigated time range is demonstrated:

• Scheduler Server-Filtering Demo.

With the above example, once you navigate to another date/view the DataSource read will be successfully executed, thus retrieving the corresponding view records.
