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.

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

The Button TagHelper is missing in the Visual Studio 2022 IntelliSense. 

### Reproduction of the problem

Create a Telerik UI for ASP.NET Core application (.NET 6) and try to insert a Button TagHelper by using the IntelliSense. It appears that not all available Telerik UI components are available in the suggested list.

### Environment

* **Visual Studio Professional 2022 version: 17.1.0 Preview 1.1

* **Kendo UI version: 2021.3.1109
* **jQuery version: 1.12.4
* **Browser: [all]

Dear Telerik Team

I have recently found a bug in the asp.net core Scheduler.

 What I did (using this demo):

1. Created a daily event

2. Edited the second event (the current occurrence) and saved it

3. Tried to edit the second event again

The problem is now that the popup if I want to edit the current occurrence or series still showed up but it should not.

We had the same problem also on our asp.net core application.

Best Regards

Jan

Hi!

We're using a drop down list as a grid cell's edit template, but.. our users are unable to properly edit the rows at the bottom of the grid due to drop down list going off the page, and closing when they attempt to scroll.

any ideas?

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"

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

1. Run the attached sample project:
   TelerikAspNetCoreApp100.zip
2. A child node is returned as checked from the server.
3. Note the difference between the state of the parent node checkbox in the Core TreeView (incorrect) and in the Kendo UI TreeView (correct).

Current behavior

The parent node's state remains "unchecked".

Expected/desired behavior

The parent node's state should be "indeterminate".

Workaround:

Attach a DataBound event handler to the TreeView:

<kendo-treeview name="DataRestrictionTree" load-on-demand="false" datatextfield="Name" on-data-bound="onDataBound" >

In the handler call the TreeView's updateIndeterminate API method:

function onDataBound(e) {
	var treeview = $("#DataRestrictionTree").data("kendoTreeView");
	treeview.updateIndeterminate();
}

Environment

• Kendo UI version: 2020.2.513
• jQuery version: x.y
• Browser: [all]

the header display 5/21 for 21 may, but should be 21/5 for French culture

no translation for Export PDF : "Export to PDF" should be "Exporter en PDF" in french Translation

There is an issue when you copy /paste a bullet list from a Microsoft word document.

• The numbers are not correct (See attached screenshot)
• If you started a new line you don't get a new number for that hierarchical level. Instead, you just get a new line.

Hello good afternoon all right?

I am developing a code where I create a base model of a window and use javascript to be able to define data like autura, width, content (URL) and etc ...
In the example I am doing, I have a menu that according to the ID of the item that I clicked on the menu, it performs a function and according to the ID, it defines the data of the Window, as I do not have a component like "RadWindowManager" to facilitate this part of the creation, I am doing this process:

Component Code:

<nav class="navbar navbar-expand-xl navbar-light bg-light">
        <a class="navbar-brand" href="#">
            <div> <img src="~/images/selo.png" class="pull-left imagem" /> </div>
        </a>
        <a class="navbar-brand" href="#">
            <img src="~/images/softlux.png" class="logo_posicao" alt="">
        </a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarText">
            <ul class="navbar-nav mr-auto">
                        <li class="dropdown nav-text">
                            <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('3,0')">
                                Example Window 1
                            </a>
                        </li>
                        <li class="dropdown nav-text">
                            <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('6,0')">
                                Example Window 2
                            </a>
                        </li>
                        <li class="dropdown nav-text">
                            <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('12,0')">
                                Example Window 3
                            </a>
                        </li>
            </ul>
        </div>
</nav>

@(Html.Kendo().Window()
    .Name("FrmGrid")
    .Resizable()
    .Draggable()
    .Content("Loading...")
    .Visible(false)
    .Modal(false)
    )

Scripts Code:

<script type="text/javascript">
        function aoClicar(idItem) {
            switch (idItem) {
                case "3,0":
                    var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");

                    janela.setOptions({
                        title: "Table of Environments",
                        width: 980,
                        height: 440
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Ambiente/Index'    // Open a Controller and Action as Frame
                    });

                    janela.center().open();
                    break;
                case "6,0":
                    var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");

                    janela.setOptions({
                        title: "Table of Professions",
                        width: 980,
                        height: 400
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Profissao/Index'    // Open a Controller and Action as Frame
                    });

                    janela.center().open();
                    break;
                case "12,0":
                    var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");

                    janela.setOptions({
                        title: "Table of reasons",
                        width: 980,
                        height: 560
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Motivo/Index'    // Open a Controller and Action as Frame
                    });

                    janela.center().open();
                    break;
                default:
                    alertify.error('Window not disponible.');
            }
        }
</script>

However, I noticed 2 problems in Defining Options such as height, width, title, and content
If I use this method to define:

janela.setOptions({
    title: "Table of reasons",
    width: 980,
    height: 560
});

The final result of the window looks like this:

Note that the Content Frame is passing outside the window border, or in case the background shadow of it, in other browsers the size may even follow the pattern of the shadow, but in Google Chrome you get this part beyond the limit.

If I use this method to set the properties:

var janela = $("#FrmGrid").kendoWindow({
        title: "Table of reasons",
        width: 980,
        height: 560
    }).data("kendoWindow");

When you create the first window, you create it without problems:
