Hello,

We are subscribing to the change event of scheduler on clicking any event/Slot , the functionality works fine with window machines.

In iPad the change event gets triggered on clicking  any part of scheduler. for instance when i click the show Full day text below it triggers the change event in iPad but not in windows.

Please let us know how to restrict change event to be triggered only when a slot/event is selected in iPad.

 

 

Thanks.

I would like to request to add HtmlAttributes to the Kendo UI Dialog's buttons to help make styling easier.  For example, I'd like to add a class to the confirm button rather than use the k-primary class.

We are upgraded from MVC 5 to MVC-Core and using now your core components (latest version).

In our AutoComplete box, we get now a NullReference exception, without changing anything at our codebase.

 

Generated Script from Kendo MVC-Core:

kendo.syncReady(function(){jQuery("#txtSearchForLink").kendoAutoComplete({"select":insertLink.searchResultSelected,"dataTextField":"Text","filter":"Contains","footerTemplate":jQuery('#searchResultFooterTemplate').html(),"minLength":0,"placeholder":"Suchen","template":jQuery('#searchResultTemplate').html(),"dataSource":{"type":"aspnetmvc-ajax","transport":{"read":{"url":"/Orphy/Search/GetQuickSearchData","data":insertLink.onAdditionalData}},"serverFiltering":true,"serverGrouping":true,"sort":[{"field":"Weight","dir":"desc"}],"group":[{"field":"GroupName","dir":"desc"}],"filter":[],"schema":{"data":"Data","model":{"id":"Id"}}}});});

 

Debugging:

-> context.Count == 0 -> so Null will returned
-> Here you access the property Memeber of Null ... ?

Call Stack:

Bug report

The Kendo UI Sortable for ASP.NET Core assumes that all selectors are by "id".

Reproduction of the problem

1. Set the .For() option of the Sortable widget to a class selector:

@(Html.Kendo().Sortable()
    .For(".k-grid table")
    // . . . 
)

2. Inspect the page source.

3. The following string is rendered:

<script>
    kendo.syncReady(function () { jQuery("\\.k-grid table").kendoSortable(// options) });
</script>


Expected/desired behavior

The Sortable widget should allow for passing any jQuery selectors.

Environment

Hello,

 

When I try to create a Telerik UI project for .NET Core 3.0 using menu and grid options the project gets created and runs correctly, however when I try to add a new view or controller there appears to be an issue with the scaffolding (even when creating a partial view) and the creation fails.

Note: I was able to get the project to sort of work only when I added a bunch of libraries it was complaining about (see attached), however the views do not update when I make changes except only when rebuilding which does not seem correct.

Hi!

We're using a drop down list as a grid cell's edit template, but.. our users are unable to properly edit the rows at the bottom of the grid due to drop down list going off the page, and closing when they attempt to scroll.

 

any ideas?

Using .Net Core 3.0

ToDataSourceResult raises an exception if the DataSourceRequest has Aggregates

the exception says that there is no constructor with the following signature:

Void Microsoft.CodeAnalysis.CSharp.CSharpCompilationOptions(
	Microsoft.CodeAnalysis.OutputKind, 
	Boolean, 
	String, 
	String, 
	String, 
	Collections.Generic.IEnumerable`1<String>, 
	Microsoft.CodeAnalysis.OptimizationLevel,

	String, 
	Collections.Immutable.ImmutableArray`1<Byte>, 
	Nullable`1<Boolean>,

	Boolean, 
	Boolean, 
	Microsoft.CodeAnalysis.XmlReferenceResolver, 
	Microsoft.CodeAnalysis.SourceReferenceResolver, 
	Microsoft.CodeAnalysis.MetadataReferenceResolver, 
	Microsoft.CodeAnalysis.AssemblyIdentityComparer, 
	Microsoft.CodeAnalysis.StrongNameProvider, 
	Boolean, 
	Microsoft.CodeAnalysis.MetadataImportOptions, 
	Microsoft.CodeAnalysis.CSharp.NullableContextOptions
)

 

I traced the error down to the method that causes it :

CSharpCompilation CreateCompilation(SyntaxTree syntaxTree)
maybe it needs to use an updated Microsoft.CodeAnalysis.CSharp nuget that supports .Net Core 3.0

There is an issue when you copy /paste a bullet list from a Microsoft word document.

  • The numbers are not correct (See attached screenshot)
  • If you started a new line you don't get a new number for that hierarchical level. Instead, you just get a new line.

When visible attribute is set to false for a panelbar-item, the item remains visible when the widget is rendered.

Reproduction of the problem

<kendo-panelbar name="project">
        <items>
            <panelbar-item text="Storage" expanded="true">
                <items>

                </items>
            </panelbar-item>
        </items>
</kendo-panelbar>

Current behavior

Adding visible attribute to panelbar-item does not change its visibility.

Bug report

In Core when the ComboBoxFor helper is used as an editor in a Grid (Shared/EditorTemplates) and its Name is set, the Grid does not render and no exception is displayed, to indicate that the Name option should not be set.

Reproduction of the problem

Reproducible in the Editing custom editor Grid demo.

  1. Set the ComboBox' Name in the ClientCategory.cshtml template
@(Html.Kendo().ComboBoxFor(m => m)
    .Name("CategoryID")
    .DataValueField("CategoryID")
    .DataTextField("CategoryName")
    .BindTo((System.Collections.IEnumerable)ViewData["categories"])
)

Current behavior

We throw an exception when the Name is set (e.g. if the ComboBox is used outside of a Grid), but in this scenario it is not displayed.

Expected/desired behavior

An exception is thrown and its message is displayed.

Bug report

The data attributes are not rendered for the DropDownlist when bound to Model in Razor Pages.

Reproduction of the problem

View:

@page
@model TelerikAspNetCoreApp12.Pages.IndexModel

<form>
    @(Html.Kendo().DropDownList()
            .Name("fabric")
            .OptionLabel("Select...")
            .DataTextField("Text")
            .DataValueField("Value")
            .BindTo(Model.Data)
            .Filter("contains")
    )
    <input type="submit" />
</form>

Back end:

namespace TelerikAspNetCoreApp12.Pages
{
    public class IndexModel : Microsoft.AspNetCore.Mvc.RazorPages.PageModel
    {
        public List<TestModel> Data { get; set; } = new List<TestModel>();

        public void OnGet()
        {
            for (int i = 1; i <= 100; i++)
            {
                Data.Add(new TestModel() { Text = "product" + i, Value = i.ToString() });
            }
        }
    }
}

Model:

namespace TelerikAspNetCoreApp12.Models
{
    public class TestModel
    {
        [Required(ErrorMessage = "Please select")]

        public string Text { get; set; }

        public string Value { get; set; }
    }
}

Inspect the input field for the DropDownList. It does not have data-val and data-val-required attributes.

Current behavior

The data attributes are not being rendered.

Expected/desired behavior

The data attributes should be rendered.

When a model property is decorated with data annotation attributes, the RadioButton HtmlHelper does not properly render the data-val and data-val-required attributes on the element.

The Menu TagHelper does not render correct links for its items when the asp-page attribute is used.

With area it does not render a link at all:
<menu-item text="Home" asp-area="Products" asp-controller="Home" asp-action="About"></menu-item>

Without area it renders an incorrect link
<menu-item text="Login" asp-area="Products" asp-page="/Books"></menu-item>

Hi Kendo Team,

I am working on Kendo UI ASP.NET Core Grid binding with SignalR. But while starting Hub and providing the Promise, I am facing an error "The "promise" option must be a Promise."

I am following this URL for reference: https://demos.telerik.com/aspnet-core/grid/signalr .

Checked on your website as well, but the issue is also coming there. Here is the URL: https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.signalr

In this link, when clicking on "Open In Dojo" button, it opens a new window, then clicks on the Run button. It will generate an error in the console "Uncaught Error: The "promise" option must be a Promise.". 

Please check the attached snapshot.

Please reply asap. Thanks in advance!
