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);
    })
    //....
)

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);
        });

Environment

• Kendo UI version: 2024.1.319
• jQuery version: Related Supported Versions
• Browser: all

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

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

• Kendo UI version: 2024.2.514

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.

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 + "]");

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

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:

Bug report

When enabling Editing for the Grid or TreeList a "No License" overlay is displayed in the following scenarios:

Reproduction of the problem

• Grid: overlay is displayed on load

@(Html.Kendo().Grid<TelerikMvcApp13.Models.OrderViewModel>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.OrderID).Filterable(false);
        columns.Bound(p => p.Freight);
        columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
        columns.Bound(p => p.ShipName);
        columns.Bound(p => p.ShipCity);
        columns.Command(c => c.Edit());
    })
    .Editable(e=>e.Mode(GridEditMode.PopUp))
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Model(m=>m.Id(o=>o.OrderID))
        .Read(read => read.Action("Orders_Read", "Grid"))
        .Update(read => read.Action("Orders_Update", "Grid"))
        .Create(read => read.Action("Orders_Create", "Grid"))
        .Destroy(read => read.Action("Orders_Destroy", "Grid"))
    )
)

• TreeList: initially there is no overlay. Clicking on "Edit" button shows overlay and "No License" popup.

@(Html.Kendo().TreeList<Kendo.Mvc.Examples.Models.TreeList.EmployeeDirectoryModelPopUp>()
    .Name("treelist")
    .Toolbar(toolbar => toolbar.Create())
    .Columns(columns =>
    {
        columns.Add().Field(e => e.FirstName).Width(220).Title("First Name");
        columns.Add().Field(e => e.LastName).Width(100).Title("Last Name");
        columns.Add().Field(e => e.Position);
        columns.Add().Field(e => e.HireDate).Format("{0:MMMM d, yyyy}");
        columns.Add().Field(e => e.Phone).Width(200);
        columns.Add().Field(e => e.Extension).Width(140).Title("Ext").Format("{0:#}");
        columns.Add().Width(300).Command(c =>
        {
            c.CreateChild().Text("Add child");
            c.Edit();
            c.Destroy();
        });
    })
    .Editable(e => e.Mode("popup"))
    .DataSource(dataSource => dataSource
        .Create(create => create.Action("Create", "EmployeeDirectory"))
        .Read(read => read.Action("All", "EmployeeDirectory"))
        .Update(update => update.Action("Update", "EmployeeDirectory"))
        .Destroy(delete => delete.Action("Destroy", "EmployeeDirectory"))
        .Model(m =>
        {
            m.Id(f => f.EmployeeId);
            m.ParentId(f => f.ReportsTo);
            m.Expanded(true);
            m.Field(f => f.FirstName);
            m.Field(f => f.LastName);
            m.Field(f => f.ReportsTo);
            m.Field(f => f.HireDate);
            m.Field(f => f.Extension).DefaultValue(0);
            m.Field(f => f.Position);
        })
    )
    .Height(540)
)

Expected/desired behavior

No overlay and popup should be displayed in case of valid license.

Environment

• Kendo UI version: 2025.1.211

I am seeing that once a grid checkboxlist column filter exceeds about 1000 items the wait time appears to increase non-linearly (performance is worse than linear.)  For example, with 3,000 items the page freezes for about 30 seconds.  The data is fetched in under 50 milliseconds, so the vast majority of this time appears to be processing by Kendo.

Please see the attached for my configuration.

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

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,

I would like to request to add an Html/Tag Helper for the kendo.ui.icon.  

Thanks!

Hello,

Object doesn't support property or method 'syncReady' I am getting this error and not able to resolve that issue. I am using visual studio core and imported Telerik.ui.for.aspnet.core.trial. I also imported the js of Kendo.Ui.Core . but not able to resolve the issue. Please help

Thanks

Allow general configuration of SuggestionOperator, as is available for Operators.

I can do something like this in GridFilterableSettingsBuilder --

  filterable.Operators(operators => operators
    .ForString(str => str
      .Clear()
      .Contains("contains"))

I would like to also be able to do this -- 

  filterable.SuggestionOperator(FilterType.Contains)

Be able to bind the DataSource to data without a separate controller and AJAX fetch for use with Razor Pages.

The use case is a shared data source that drives multiple components on a page for example a chart and grid filtered with an auto complete box.

In a grid I can do this:

@(Html.Kendo().Grid(Model.Data)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.Description).Title("Description");
        columns.Bound(p => p.RecordCount).Title("Number Sold").Width(130);
        columns.Bound(p => p.TotalValue).Title("Total Value").Width(130);
        columns.Bound(p => p.AverageValue).Title("Average Value").Width(130);
        columns.Bound(p => p.Rank).Title("Rank").Width(130);
        columns.Bound(p => p.RankMax).Title("Bananas").Width(130);
        columns.Bound(p => p.LowerQuartile).Title("LowerQuartile").Width(130);
        columns.Bound(p => p.Median).Title("Median").Width(130);
        columns.Bound(p => p.UpperQuartile).Title("UpperQuartile").Width(130);
    })
    .Sortable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .ServerOperation(false)
    )
)

Would want to be able to do same with the DataSource like:

@(Html.Kendo().DataSource(Model.Data)
    .Name("dataSource1")
    .Ajax(dataSource => dataSource
        .ServerOperation(false)
    )
    )
