In this screenshot, End Date and Subm Is Open are "nested" properties, and Prod Date and Is LatestVersion are *not* nested.  The row filter functionality is not displaying the correct row filter widget.

Here's a data sample:

The current demo is showing  a contains predicate. To enhance the current application, I am requesting the feature to use a starts with predicate to meet a practical business need. 

The minimum length property will need to changed to 1 to limit the number of characters to be typed.

It would be nice to extend dialog like office 365 right dialog ( docked to the right).

It would be nice to have a dropdown button with a container

In the example below products is actually DbSet<Product>

public async Task<ActionResult> Products_Read([DataSourceRequest]DataSourceRequest request)
{
    using (var northwind = new SampleEntities())
    {
        IQueryable<Product> products = northwind.Products;
        DataSourceResult result = await products.ToDataSourceResultAsync(request);
        return Json(result);
    }
}

Under the hood the ToDataSourceResultAsync call is executed inside Task.Run

And that Task.Run is calling sync methods of IQueryable which means EntityframeworkCore queries are not taking place with async I/O

Whilst I'm aware that I can create a HTML label and add the k-label class. I feel that a Label and a LabelFor are essential parts of the toolkit to prevent brittle code getting created when/if the labels that are created within the toolkit have other requirements

I have created my own implementation for now but I think this should be added to your roadmap, especially as it's such a simple thing to do

Bug Report

The Pickers are not bound to model value when a nullable DateTime is set.

Reproduction of the problem

1. Create a model with a nullable DateTime property

        public class MyModel
        {
              public DateTime? Birthday { get; set; }
        }
   

2. Declare either a DatePickerFor, DateRangePickerFor, DateInputFor, or TimePickerFor Helpers

       @(Html.Kendo().TimePickerFor(m => m.Birthday))
   

3. Notice, that the value has not been bound accordingly.

Current behavior

The Pickers are not bound to model value when nullable.

Expected behavior

The Pickers are not bound to model value when a nullable DateTime is set.

### Bug report

When building the scripts through the 'npx gulp scripts' command, there is an error "Error: Cannot find module './build/gulp/kendo-version'".

### Reproduction of the problem

Download any of the source bundles (Core, MVC, jQuery) and try to build the scripts.

### Environment

Bug report
For the Telerik Scheduler Timeline View, since the update from somewhere in between version 2022.3.1109 to 2024.2.154, a custom timeline view cannot be selected if the view name has dot(s) in its name (e.g. "kendo.ui.customTimelineView").

Reproduction of the problem

Add a custom Timeline View by extending the kendo.ui.TimelineView

Current behavior

Unlike older versions (I know that it worked with version <= 2022.3.1109, but don't know when exactly it was introduced)  now the ui blocks, when the custom select view button is clicked. Specifically, the problem is in kendo.scheduler.js at line 4554:

var viewElementToSelect = that.toolbar.find("[" + kendo.attr("name") + "=" + name + "]");

Expected behavior

In this code line, the find method does not work when the variable "name" contains something like "kendo.ui.CustomTimelineView". As a solution, I suggest escaping the name beforehand:

var nameEscaped = $.escapeSelector(name);
var viewElementToSelect = that.toolbar.find("[" + kendo.attr("name") + "=" + nameEscaped + "]");

Overview

Currently, the Telerik UI for ASP.NET Core DataSource does not expose a Deferred() API configuration. In comparison to its Telerik UI for ASP.NET MVC counterpart.

It would be beneficial to expose the ability to defer the component in the following manner:

@(Html.Kendo().DataSource<TelerikMvcApp119.Models.OrderViewModel>()
    .Name("ds")
    .Ajax(dataSource => dataSource
		.Read(read => read.Action("AssetType_Read", "AssetTypes"))
	)
    .Deferred()
)

It will also enable users to employ CSP using a granular deferred initialization into a separate script tag. Annotated with the nonce attribute

Current behavior

The Telerik UI for ASP.NET Core DataSource does not expose a built-in configuration for deferring the DataSource.

Expected/desired behavior

The Telerik UI for ASP.NET Core DataSource should expose a built-in configuration for deferring the DataSource.

Environment

• Kendo UI version: 2024.2.514
• Browser: [all]

Bug report

TabStrip is not CSP compliant when the Selected() API configuration is enabled.

Reproduction of the problem

1. Create an application with CSP headers
2. Create a TabStrip and set the Selected() API configuration for one of the items

@(Html.Kendo().TabStrip()
    .Name("tabstrip")
    .Items(items =>
    {
        items.Add().Text("Details")
		.Selected(true)
		.LoadContentFrom("Details", "Home", Model);
    
    })
)

Current behavior

Setting the Select() API configuration will lead to the following Content Security Policy Header Report Error.

Refused to apply inline style because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'style-src' was not explicitly set, so 'default-src' is used as a fallback.

Expected/desired behavior

Setting the Select() API configuration should not lead to a Content Security Policy Header Report Error.

Environment

Add a 3 state mode to the Switch component (like it is already implemented in the Telerik UI for WPF) or create new component with that feature.

Example:

Bug report

When the Columns.Command.Edit.UpdateText property is set to Update, the text will not be modified and will remain as the default value Save.

Reproduction of the problem

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Command(command => { 
            command.Edit().UpdateText("Update");  //Will not work
        }).Width(250);
    })
    //....
)

REPL
https://netcorerepl.telerik.com/wIuyvtcO41rAa82G36

Expected/desired behavior

The text should change to the specified content within UpdateText.

Workaround

Set the text via JavaScript using the setOptions method and columns.command.text:

        $(document).ready(function(){
            var grid = $("#grid").data("kendoGrid");
            var options = grid.getOptions();
            //set the text for the first command in the last column
            // as shown in the second example on:
            //https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.command#columnscommandtext
            options.columns[4].command[0].text = { edit: "Edit", update: "Update" };
            grid.setOptions(options);
        });

 When uncheck "Use localization" while create project the Localization resources are still auto copied while publish the project.

The resources are part of the telerik.ui.for.aspnet.core.yyyy.q.mmdd.nupkg and therefore are copied to the bin folder regardless of the  "Use localization" option. The "Use localization" option controls the availability only of the messages files.

This a feature request for providing another lightweight NuGet which does not contain the localization dlls that could be used for non-localized projects.

At this stage, the Serialize() method depends on Newtonsoft.Json:

using Newtonsoft.Json;

namespace Kendo.Mvc.Infrastructure
{
    public class DefaultJavaScriptSerializer : IJavaScriptSerializer
    {
        public string Serialize(object value)
        {
            return JsonConvert.SerializeObject(value).Replace(@"<", @"\u003c").Replace(@">", @"\u003e");
        }
    }
}

Is it possible to remove the dependency and use the System.Text.Json serializer instead?

### Bug report

When the deferred scripts are created, the script source points at the root of the application instead of the application's root directory.

### Reproduction of the problem

Enable the global deferred initialization and call the @(Html.Kendo().DeferredScriptFile()) method.

The rendered script tag is:  <script src="/kendo-deferred-scripts-XXXX.js"></script>

But it must be: <script src="/MyWebsite/kendo-deferred-scripts-XXXX.js"></script>

### Solution:

If you add a tilde in the Url.Content(), the generated script file must be located as expected:

public HtmlString DeferredScriptFile(string nonce = "")
{
           ...
            var scriptResult= hasDeferredScritps ? $@"<script src=""{urlHelper.Content("~/kendo-deferred-scripts-" + guid + ".js")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')}></script>" : "";
            var styleResult = hasDeferredStyles ? $@"<link href=""{urlHelper.Content("~/kendo-deferred-styles-" + guid + ".css")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')} rel=""stylesheet""></link>" : "";
            return new HtmlString(scriptResult + System.Environment.NewLine + styleResult);
}
