As per the subject, if you use jQuery to get a Kendo TabStrip in a ComboBox change event it inserts this div into the TabStrip control:

<div class="k-tabstrip-items-wrapper k-hstack">
    <ul class="k-tabstrip-items k-reset" role="tablist"></ul>
</div>

This used to work as we were changing the selected tab in a TabStrip based on a ComboBox selection, but this no longer works. Please see the following REPL where a new div is added every time you change the ComboBox value:

Currently, the ToCamelCase() method lowers only the first letter, as per the example below:

Is it possible to create another overload of the ToCamelCase() method that transforms the string to "randomStatusId"?

Dear Telerik

The feature is related to https://www.telerik.com/account/support-center/view-ticket/1594775 this thread.

It is related to a product environment.

Scenario:

1. Save grid options in persistent storage (i.e. DB).
2. Grid operates successfully and return visits operate well with stored options being loaded with the grid.
3. Then the grid column structure or some other feature is amended during a maintenance and development request - the feature setting is contained within the stored options which are loaded with the grid. The grid functions without some of the changes because the options override the changes.
4. Behavior is unwanted so we would have to merge the new options and the old options.

Request:

Please can Telerik create functionality along the lines of:

$("#SomeGrid").data("kendoGrid").setOptions($("#SomeGrid").data("kendoGrid").mergeOptions(OptionsSaved, OptionsNew));

Hi this is a pretty basic bug. But I am using the k-i-cancel icon class but for some reason it is showing the settings icon?

It would be useful to have a grid operator for "IN" conditions. Right now we only have 2 options for an OR without having to use a custom filtering and custom clearing functions.

We have a lot of data that needs to be filtered that is not sequential.  For example purposes:

Given that a customer has a standing purchase order for parts over time.

Given that serial numbers on said parts will not be sequential and may not be even be similar enough for wildcards (if that feature is provided.)

Given that we need to filter grid data to retrieve customer number, purchase order and a set of serial numbers, we need the equivalent of:

SELECT * FROM testdatatable WHERE customer = '#####' AND purchaseorder = '#####' AND serialnumber IN ('abciqwe', 'cid235', 'sn34087', 'hpk2679');

which would be WHERE WHERE customer = '#####' AND purchaseorder = '#####' AND (serialnumber  = 'abciqwe' OR serialnumber =  'cid235' OR serialnumber = 'sn34087' OR serialnumber 'hpk2679');

So basically I would like to have the ability to have multiple OR statements and the operand could be 'contains' or 'not contains' as that would probably work better than "equal".

Our immediate need is for the MaskedTextBox.

And have modified my program.cs to add:

// Add services to the container.

builder.Services.AddControllersWithViews()

                // Maintain property names during serialization. See:

                // https://github.com/aspnet/Announcements/issues/194

                .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver());

// Add Kendo UI services to the services container"

builder.Services.AddKendo();

I copied the code from your demo into the ASP.net 6.0 Page above.

I added data properties to the Index.cshtml.cs model and changed the Value property on each Kendo object to point them. That works fine

The issue is that the formatting is not applied:

Steps to reproduce

1. Execute the code below
2. Enter some values in the Html and Kendo inputs
3. Hit the browser's back button
4. Hit the browser's forward button to redisplay the page

Current Behavior

The value in the Html Input is restored but not the value of the Kendo Input. The same behavior applies for Kendo NumericTextBox, etc.

### Bug report

If I manually enter the date in the cell the model binder parses the date as it was not an UTC and since my time zone is +2h it comes in the controller as 25.12.2021 22:00

(see the attached files)

Inside my startup.cs I have defined JsonOptions like this:

.AddNewtonsoftJson(options =>
                {
                    options.SerializerSettings.ContractResolver = new DefaultContractResolver();
                    options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
                });

In the Configure method:

var supportedCultures = new[] { new CultureInfo("bg-BG") };

app.UseRequestLocalization(new RequestLocalizationOptions
{
         DefaultRequestCulture = new RequestCulture("bg-BG"),
         SupportedCultures = supportedCultures,
         SupportedUICultures = supportedCultures
});

<script src="~/lib/kendo/js/cultures/kendo.culture.bg-BG.min.js"></script>

<script>
        kendo.culture("bg-BG");
</script>

Kendo dialog structure doesn’t use Aria landmarks properly for buttons  - this leads to a validation error

The pager control's select box renders role="listitem" but the parent is missing role="list"  - this leads to a validation error

Listviews will render role="list" even when empty - this leads to a validation error

Kendo grids use 2 tables (one for header and one for the data) which means that there are no role="cell" assigned to any of the headers  - this leads to a validation error

Scrollable grids are missing a tabindex="0" to allow for keyboard navigation - this leads to a validation error

this form doesn't have Core 2, 2.1, 3.0, 3.1 or 5 in the .Net Framework drop down. Just gonna pick 4.8 even though it doesn't apply. I am using core 5.

Can't update Razor.RuntimeCompilation to 5.0.0, because Telerik.UI.for.AspNet.Core (2020.3.1118) uses Microsoft.CodeAnalysis.Common=3.3.1 (needed >=3.7.0).

NU1107: 
 OperationalAccounting -> Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation 5.0.0 -> Microsoft.CodeAnalysis.Razor 5.0.0 -> Microsoft.CodeAnalysis.Common (>= 3.7.0) 
 OperationalAccounting -> Telerik.UI.for.AspNet.Core 2020.3.1118 -> Microsoft.CodeAnalysis 3.3.1 -> Microsoft.CodeAnalysis.CSharp.Workspaces 3.3.1 -> Microsoft.CodeAnalysis.Common (= 3.3.1).

Bug report

The StringExtensions -> ToCamelCase method(part of Kendo.Mvc.Extenstions) doesn't return the expected Camel case result.

• More details in ticket # 1458202

Reproduction of the problem

Include the Kendo.Mvc.Extenstions namespace. Define the following in a controller:

        public IActionResult Index()
        {
            string test = "RANDOMStatusId";
            test = test.ToCamelCase();

            return View();
        }

Set a debugger and see the value of the "test" variable.

Current behavior

The returned from the ToCamelCase() method value is "rANDOMStatusId"

Expected/desired behavior

The expected result returned from the ToCamelCase() method value is "randomStatusId"

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

I`m working development and produced I4.0 devices as well app systems since 3 years.  Are Telerick involve in this applications. 

Please add an option so that is possible to set Deferred rendering default setting to either true or false globally.

Currently the default is false and can only be overwritten on a control basis and not globally.

This would benefit those customers that have decided that all/most of the controls are rendered as deferred(true). Currently they have to append the Deffered(true) to each of the helpers.
