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.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Feature request

Add Refresh method to the ASP.NET Core Timeline wrapper.  It should allow user to reload the component using the current data items.

Bug report

The server filtering is not working for MultiColumnComboBox defined using a tag helper.

Reason: The initialization script returns:
..... kendo.ui.ComboBox.requestData(.....
instead of
..... kendo.ui.MultiColumnComboBox.requestData(.....

Reproduction of the problem

For reproduction details please refer to ticket: #1435798

Current behavior

The server filtering is not working and the server returns all items from the DataSource.

Expected/desired behavior

The server should filter the response based on the data coming from the view.

Environment

• Kendo UI version: 2019.3.1023
• jQuery version: x.y
• Browser: [all]

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

	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)

We have the need to create a chart to display Risk Information. Below is the image of a risk matrix as defined on pages 96 in AFPAM63-128 https://static.e-publishing.af.mil/production/1/saf_aq/publication/afpam63-128/afpam63-128.pdf -- there are more examples on page 101

Another example of a risk matrix can be seen on page 18 here -> https://static.e-publishing.af.mil/production/1/af_se/publication/afi90-802/afi90-802.pdf

I've copied the images here for convenience.

Would it be possible to add this to the Kendo Chart backlog?

IgnoreCase property is missing for the filterable options of the column:

https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI.Fluent/GridBoundColumnFilterableBuilder

The option is documented in:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.filterable.ignorecase

Hi Team

With the latest version of Kendo (Silver Theme), The selected color of a Panelbar was white now it's blackish.

Do you have a quick fix for that?

Many thanks
