Scheduler Unable to call Update WebAPI (Put)

[Ashley]

Hello,

 

I am trying to use the Scheduler control for my application. I have it reading the data from my controller fine. However, I cannot get it call the HttpPut handler correctly.

My breakpoint isnt hit & checking the traffic the responce is:

400 - Bad Request
{"":["The input was not valid."]}

 

The code I am using for the UI is:

01.@(Html.Kendo().Scheduler<MeetingViewModel>()
02.      .Name("SchedulerView")
03.      .Height(500)
04.      .Date(DateTime.Now.ToUniversalTime())
05.      .StartTime(new DateTime(2018, 11, 28, 0, 00, 00).ToUniversalTime())
06.      .MajorTick(30)
07.      .ShowWorkHours(false)
08.      .Footer(false)
09.      .Editable(edit =>
10.      {
11.          //edit.Resize(false);
12.          edit.Create(false);
13.      })
14.      .Views(views =>
15.      {
16.          views.TimelineView(timeline => timeline.EventHeight(50));
17.          //views.TimelineWeekView(timeline => timeline.EventHeight(50));
18.          //views.TimelineWorkWeekView(timeline => timeline.EventHeight(50));
19.          //views.TimelineMonthView(timeline =>
20.          //{
21.          //    timeline.StartTime(DateTime.Now);
22.          //    timeline.EndTime(DateTime.Now.AddMonths(1));
23.          //    timeline.MajorTick(1440);
24.          //    timeline.EventHeight(50);
25.          //});
26.
27.      })
28.      .Timezone("Etc/UTC")
29.      .Group(group => group.Resources("WorkCenters" /*,"Attendees"*/).Orientation(SchedulerGroupOrientation.Vertical))
30.      .Resources(resource =>
31.      {
32.          resource.Add(m => m.ScheduleRowID)
33.              .Title("Work Center")
34.              .Name("WorkCenters")
35.              .DataTextField("Text")
36.              .DataValueField("Value")
37.              .DataColorField("Color")
38.              .BindTo(@Model.AvailableWorkCenters);
39.      })
40.      .DataSource(d => d
41.          .ServerOperation(true)
42.          .WebApi()
43.          .Model(m =>
44.          {
45.              m.Id(f => f.ActivityID);
46.              m.Field(f => f.Title).DefaultValue("No title");
47.              //m.RecurrenceId(f => f.RecurrenceID);
48.              m.Field(f => f.Description).DefaultValue("No Description");
49.          })
50.          .Events(events => events.Error("error_handler"))
51.          .Read(read => read.Action("GetActivities", "Scheduler").Data("setRequestDateTimes"))
52.          //.Create(create => create.Action("Post", "Scheduler"))
53.          .Update(update => update.Action("PutActivity", "Scheduler", new { id = "{0}" }))
54.          //.Destroy(destroy => destroy.Action("Delete", "Scheduler", new { id = "{0}" }))
55.      )))

 

The code I am using for the Controller is:

15.        List<MeetingViewModel> test = new List<MeetingViewModel>();

What could be the issue for me?

Hello,

I have inspected the code provided but could not find out what may not be working correctly. In such case I would recommend you to refer to our online demo and compare your case with it where a similar scenario is working correctly and Put is triggered as expected. All the demo is also available in our offline demo Sample Application that can be downloaded from in your Telerik account.

If you still can't figure our what is not working correctly - I would recommend you to try to isolate the issue into a sample runnable project and send it so we could inspect it and be more helpful.

I have resolved this issue.

In ASP Core 2.1 the code above makes the Scheduler send the data as FormData and not Json.

 

I fixed it by changing the function to the following:

1.public IActionResult UpdateActivity(int id, [FromForm]MeetingViewModel task)
2.{
3.     //Code here
4.}

Hello,

I'm new to Telerik and I'm trying to run your Scheduler demo for Core in my Visual Studio 2017. I installed Telerik.UI.for.AspNet.Core(2019.1.115) in my VS 2016.

But when I copy the code from your demo I get an error in: @(Html.Kendo().Scheduler<Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel>()

 

Under Kendo.Mvc.Examples it cannot find "Models". Did the dll changed? How can I get to Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel ?

Hi Pablo,

You can download the examples solution with all the models in a runnable sample from your Telerik account as described in this documentation article.
