Thanks a lot.

Hi,

I have a problem with the kendo map using tag helpers, and I'm getting the error: 

Uncaught TypeError: a.mobile.ui.Scroller is not a constructor
at init._initScroller (kendo.all.js:174114)
at new init (kendo.all.js:174307)
at HTMLDivElement.<anonymous> (kendo.all.js:2435)
at Function.each (jquery.js:360)
at jQuery.fn.init.each (jquery.js:137)
at jQuery.fn.init.e.fn.(anonymous function) [as kendoMap] (http://localhost:50902/lib/kendo/2018.1.221/js/kendo.all.min.js:26:4668)
...


I tried the tag helper implementation and it's not working, neither with razor, nor jquery. Error is the same. I'm using kendo for asp.net core 2018.1.221. Do you have any idea what cause the problem? 

Kind regards,
Asmir

Just starting a major new project, and wondering if the ASP.Net Core UI wrappers are a long-term bet?

Seems to me this forum is nearly deserted, and the latest support resources are years out of date. The installation in a new project seems a home-made affair - the product just seems a marketing extension to Kendo UI to try to get more people on board. I like the concept of server side tagging like this - abstracting away as much Javascript has to be a good thing.

I'd rather bale out now if this is product is another stinker like Linq to Sql, Webforms, Silverlight or any others on the long list of turkey technologies.

Going to assume that if no response by Tuesday, it's died a death.

I am using the Telerik Grid on a dashboard-type of web page in ASP.NET Core 2.1 (with Razor pages). I need to have the contents of the Grid updated when the data presented in the Grid changes. In case there are better solutions, I will give a bit more detail.

I have 2 web apps. One, let's call it the child web app, will send a notification via SignalR to the main web app, called the parent. When the parent app receives the notification via SignalR I want to update the Telerik Grid as well as display the message contained in the SignalR notification in a Telerik Notification. 

I know that I can use SignalR directly with the Grid, but I don't see any way to preserve the data that arrives via SignalR.  I need to save the data that arrives in the SignalR message.

So, I need to do this:

1. Force the Grid to re-read and display the data when the web app receives a SignalR notification.

2. At the same time display a Telerik Notification.

Again, this is in an ASP.NET Core web app with Razor pages using .NET Core 2.1

I've got a grid, using a pop-up editor. This works, but doesn't pick up the custom edit form in the EditorTemplatesfolder of the view.

The only way I can get it to work is to specify the full path in the TemplateName setting. I'm using version v2018.2.516.

Thanks

Hello,

I created a asp.net core mvc solution. I also created a working build on Visual Studio Team Services. Next, I added a reference to Telerik.UI.for.AspNet.Core using the Telerik private Nuget feed. With this addition, the build on VSTS now fails.

I already had a Nuget Installer task in my build. I set the path to a nuget.config file in my repository. I tried with the hashed password and with a clear text password. No matter what I do, the build still fail. The build fails when the next task is executed. The task performs a dotnet restore on the asp.net mvc project.

Can you help ?

Regards,

Patrice

Hello,

the default form-reset behaviour with preloaded inputs in HTML5 is setting the value back to the loaded value. For example: I open the customer-form and the name input is loaded with value = "Hans Müller". When i change the value to "Wilfried" and reset the form, the value is changed back to "Hans Müller".

With kendo-controls however, the behaviour is different. Resetting the form clears all fields, the value in the examples becomes empty.

Is it possible to change that behaviour to the "default" behaviour (Back to loaded values)?

Any help is much appreciated.

Dima.

I am evaluating your software for purchase and have encountered the following problem. I am trying to create a grid which will have a dropdown list editor for one of its columns. According to the comment in the thread https://www.telerik.com/forums/grid-with-drop-down-not-working it should be sufficient to create a foreign key column and then provide the data necessary to populate the dropdown. This isn't working for me. The editor for the personid column should be a dropdown list, but it isn't. No errors are shown when the project is built nor when the web page is displayed. Here is my code:

ScheduleGrid.cshtml

@{
    ViewData["Title"] = "Schedule";
}
<h2>Schedule</h2>

@(Html.Kendo().Grid<SessionItemModel>()
      .Name("ScheduleGrid")
      .DataSource(d => d
         .Ajax()
         .Batch(true)
         .PageSize(7)
         .ServerOperation(false)
         .Model(model => { model.Id(p => p.pkey);  })
         .Read(r => r.Action("Read", "Schedule"))
         .Update(u => u.Action("Update","Schedule"))
         .Group(g => g.Add(p => p.daypart)))
      .Columns(c => {
         c.Bound(m => m.pkey).Visible(false);
         c.Bound(m => m.sessionkey).Visible(false);
         c.Bound(m => m.daypart).Title("Day Part").Visible(false);
         c.Bound(m => m.type).Visible(false);
         c.Bound(m => m.slot).Title("Slot");
         c.ForeignKey(m => m.personid, (System.Collections.IEnumerable)ViewData["persons"], "personid", "name").Title("Name");
         c.Bound(m => m.editable).Visible(false);
      })
      .Groupable(false)
      .Pageable()
      .Editable(e => e.Mode(GridEditMode.InCell))
      )

ScheduleController.cs

   public class ScheduleController : Controller {
      private sessionsRepository repo = new sessionsRepository();

      public IActionResult Index() {
         ViewData["persons"] = repo.GetPersons();
         return View("ScheduleGrid");
         }

      public ActionResult Read([DataSourceRequest] DataSourceRequest request) {
         List<SessionItemModel> sessions = repo.GetItems();
         DataSourceResult result = sessions.ToDataSourceResult(request);
         return Json(result);
         }

      [HttpPost]
      public ActionResult Update([DataSourceRequest] DataSourceRequest request,  [Bind(Prefix = "models")]IEnumerable<SessionItemModel> items) {
         // update sessions here

         List<SessionItemModel> sessions = repo.GetItems();
         DataSourceResult result = sessions.ToDataSourceResult(request);

         return Json(result);
         }
      }

I can set toolbar collapse use follow code:

@(Html.Kendo().Spreadsheet()
        .Name("spreadsheet")
        .HtmlAttributes(new { style = "width:100%" })
        .Toolbar(false)
        .Sheetsbar(false)....

but it dose not work use taghelper.

<kendo-spreadsheet name="spreadsheet" style="width: 100%" sheetsbar="false" >
        <toolbar enabled="false" />
