Currently, when dynamically appending menu items using the append() method, there is no built-in support to specify an icon via an icon, iconClass, or similar property — unlike other Kendo UI components such as kendo.ui.Button, which allow this directly.

To include an icon today, we must use inline HTML within the text property and set encoded: false, like so:

menu.append({
    text: '<span class="k-icon k-i-plus"></span> Add Item',
    encoded: false
});

While this workaround functions, it's not as clean or consistent as using a dedicated iconClass or icon option.

Please consider adding official support for an iconClass, icon, or similar property when using append() with kendo.ui.Menu, aligning it with how other Kendo components handle icons.

This would:

  • Improve API consistency across Kendo components.
  • Simplify code for dynamic menu updates.
  • Eliminate reliance on raw HTML and manual encoding flags.

I'm using an OData datasource to populate the grid.  To make matters worse, the Autocomplete retrieves data for *all* of the grid columns.  I'd say the default behavior should only retrieve the current column's data and preferably use OData groupby to limit the results to distinct values.

Interestingly, the CheckBoxList filter *is* populated from the current grid data, behaving as expected.  

My page is attached and the issue is occurring in the detail grid where Server Filtering is disabled.

Hi Team,

Currently, Telerik.Licensing NuGet package only has target for netstandard2.0, netframework462 and net6.0. I cannot use .NET 6 for my .NET 9 application because .NET 6 is out of support. 

This is a feature request to either

  • Remove the net6.0 TFM and reply only on netstandard2.0
    • or
  • Add net8.0 and net9.0 targets.

Thank you,

Arthur

Serializing DataSourceResult when it contains several groups is significantly slower compared to serializing the object when no grouping is used. Consider ways to improve the performance. For more context and an example, see Ticket ID: 1677867.

I am using the Kendo UI Upload Control and wanted to allow for multiple files in synchronous mode, but when adding multiple files at the same time, they are grouped together in the same line item. Is there a way to have each separate file as its own line item and remove item individually if we upload multiple files together? Currently while uploading multiple files and removing a single one is not supporting in synchronous mode.

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

*** Support ticket created by Telerik by Progress staff ***
*** Please follow-up with additional details, if necessary. Thank you. ***

There is currently no built-in feature to dynamically disable pagination when the number of grid rows is fewer than the defined page size. I need a way to automatically disable pagination when the number of records is less than or equal to the page size for a smoother user experience. Fig: 1(a)



In the above image, After filtering the data, despite current records are less than the page size but pagination is still appearing.

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.

 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?

Running WAVE on websites that use the Slider throw up a load of alerts to do with "Redundant title text" and "Unlabeled form control with title".

You can see examples of this on any demo page such as the Basic Usage one.

Can you please remove the offending attributes - or come up with values that don't throw these issues up? I'm not sure if they're in place to work with ToolTips, but if we elect not to support ToolTips (which is default behaviour) then they are effectively redundant.

I don't want to have to do this myself in script because it is an unnecessary overhead and may cause downstream issues in your code.

I'm looking to add the Nonce to the standard inline kendo initialization scripts rather that having to defer initialization and output the initialization scripts in a script tag with a nonce, as demonstrated in the documentation https://docs.telerik.com/aspnet-core/html-helpers/helper-basics/content-security-policy#for-r1-2023-sp1-and-later-working-with-telerik-ui-for-aspnet-mvc-components

Consider the use of TextWriter async methods for the HTML Helpers, for example the WriteInitializationScript methods.  In certain scenarios the use of the synchronous methods causes an exception: System.InvalidOperationException: Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true instead.

This can be resolved by explicitly enabling synchronous operations

services.Configure<IISServerOptions>(options =>
    {
        options.AllowSynchronousIO = true;
    });

though synchronous operations have been disabled by default at framework level as of .NET 3.0.
