Reproduction of the problem

Declare a Html.Kendo().TextArea() in ASP.NET project

Current behavior

If there is a text binding to the item that has a script tag injected, the Core component will break its initialization instead of encoding it as it is done for the Telerik UI for ASP.NET MVC DropDownList helper.

        @(Html.Kendo().DropDownList()
            .Name("DDL")
            .HtmlAttributes(new { style = "width:100%" })
            .OptionLabel("Select...")
            .DataTextField("text")
            .DataValueField("value")
            .Height(310)
            .BindTo(new List<object> {
                new { text = "Test", value = 0 },
                new { text = "<script>alert(123)</script>", value = 0 }
            })
        )

Result:

### Bug report

When a specified gird column has a property '.EditorTemplateName("Date")', the default DatePicker editor is not rendered properly.

### Reproduction of the problem

1. Create a new Telerik ASP.NET Core MVC Application by using the "Create New Project Wizard". Use the "Grid and Menu" Template;

2. Make the Grid "InLine" editable;

3. Set the property '.EditorTemplateName("Date")' to the "OrderDate" grid column;

4. Run the application and try to edit an existing record. The DatePicker editor is not displayed as expected.

Attached is a runnable sample for reproduction.

### Expected/desired behavior

The closing bracket in the DatePicker configuration should be moved at the end:

//Current configuration
@model DateTime?

@(Html.Kendo().DatePickerFor(m => m)).HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("")})

//Updated configuration
@model DateTime?

@(Html.Kendo().DatePickerFor(m => m).HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("")}))

### Bug report

When the Grid group paging is enabled, and the Grid is grouped, when the user search through the built-in search panel, and expand a specified group, an infinite loop appears. The Grid sends Read requests, and the server returns empty "data" property.

### Reproduction of the problem

1) Create a Grid bound to remote data and enable the group paging feature.

2) Group the Grid by a specified column.

3) Enter a value in the Grid search panel (the grouped data is filtered).

4) Expand a specified group --> it causes an infinite loop.

5) Open the browser Network tab to review the Read requests.

A Dojo sample for reproduction: https://dojo.telerik.com/EsuQoQiP

### Expected/desired behavior

The grouped Grid data should be filtered through the search panel as expected.

### Environment

* **Kendo UI version: 2023.1.117
* **jQuery version: 1.12.4

### Bug report

When the Virtualization of the MultiColumnComboBox is enabled, the table headers and rows are not aligned correctly.

### Reproduction of the problem

A Dojo sample for reproduction: https://dojo.telerik.com/ORalaWoq

The tables and rows are aligned as expected when using version 2021 R3 SP2 (2021.3.1207).

A temporary workaround:

<style>
    .k-table-list .k-table-group-row, .k-table-list .k-table-row {
        display: inline-flex;
    }
</style>

### Expected/desired behavior

The headers and rows should be aligned correctly when the Virtualization is enabled.

* **jQuery version: 1.12.4
* **Browser: [all]

### Bug report

The attributes set through the "HtmlAttributes", "ContentHtmlAttributes", and "LinkHtmlAttributes"methods are not applied to the TreeView items.

### Reproduction of the problem

1. Create a TreeView and set attributes by using the "HtmlAttributes", "ContentHtmlAttributes", "LinkHtmlAttributes"methods:

@(Html.Kendo().TreeView()
    .Name("treeview-kendo2")
    .Items(treeview =>
    {
        treeview.Add().Text("My Documents")
        .SpriteCssClasses("k-icon k-i-globe")
        .Expanded(true)
        .Url("/")
        .HtmlAttributes(new { @class = "fairydust1" })
        .ContentHtmlAttributes(new { data_navigate = "navigate_content", @class = "trigger", title = "content_title" })
        .LinkHtmlAttributes(new { data_navigate = "navigate_link", @class = "trigger", title = "content_link" });
    })
)

2. Run the page and inspect the TreeView item.

### Expected/desired behavior

The attributes are serialized and rendered.

### Environment

### Bug report

When the Dialog is configured with actions and the Content Security Policy is enabled, it throws an "Invalid template" error.

### Reproduction of the problem

1) Configure a Dialog widget with actions and set the CSP with the following content:

<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline' https://kendo.cdn.telerik.com https://code.jquery.com; style-src 'self' 'unsafe-inline' https://kendo.cdn.telerik.com;" />

2) Open the browser console to review the error.

A Dojo sample for reproduction: https://dojo.telerik.com/ULOyazUC

### Expected/desired behavior

The Dialog should be rendered correctly without using the 'unsafe-eval' keyword in the "script-src" directive.

### Workaround

Insert the following script before the Dialog initialization:

 <script>
    kendo.ui.Dialog.fn._mergeTextWithOptions = function(action) { var text = action.text; if(text) { return kendo.isFunction(text) ? text(this.options) : text; } return ""; }
</script>

### Bug report

Adding the [Authorize(Roles = "Admin, User")] attribute at Controller or Actions within the Controller does not show the Menu items.

### Reproduction of the problem

1. Create an application with authorization and add "Admin" and "User" roles.

2. Add the [Authorize(Roles = "Admin, User")] attribute to a specified Action method within the Controller:

public class HomeController : Controller
{
        public IActionResult Index()
        {
            return View();
        }

        [Authorize(Roles = "Admin, User")]
        public IActionResult Security_Information()
        {
            return View();
        }
}

3. Add a Menu:

    @(Html.Kendo().Menu()
        .Name("htmlhelperMenu")
        .SecurityTrimming(true)
        .Items(menu =>
        {
            menu.Add().Text("Home").Action("Index", "Home");
            menu.Add().Text("Security Information").Action("Security_Information", "Home");
        })
    )

    <kendo-menu name="taghelperMenu">
        <items>
            <menu-item text="View Inventory">
                <sub-items>
                    <menu-item text="Home" asp-controller="Home" asp-action="Index"></menu-item>
                    <menu-item text="Security Information" asp-controller="Home" asp-action="Security_Information"></menu-item>
                </sub-items>
            </menu-item>
        </items>
    </kendo-menu>

3. The "Security Information" Menu item is not visible when the user is logged as "Admin" or as "User".

### Expected/desired behavior

The "Security Information" Menu item should be visible when the [Authorize(Roles = "Admin, User")] attribute is added to the respective Action/Controller and the user is logged as "Admin" or as "User".
