### Bug report

The DropDownTree TagHelper with enabled checkboxes does not submit the selected options when it is bound to a Model property.

### Reproduction of the problem

1. Define a DropDownTree TagHelper as a form editor and and enable its checkboxes.

2. Bind the editor to a Model property (an array of integers).

3. Submit the form and examine the submit request payload. The values of the selected items are missing.

//Model
public class TestFormModelClass
{
  public int[] MonthsSelectedIds { get; set; }
}

//View
@model TestFormModelClass

<form method="post">
  <kendo-dropdowntree for="MonthsSelectedIds" 
      check-all="true"
      datatextfield="Month"
      datavaluefield="Id">
      <hierarchical-datasource type="DataSourceTagHelperType.Custom">
                <schema>
                    <hierarchical-model id="id"></hierarchical-model>
                </schema>
                <transport>
                    <read url="/api/items" />
                </transport>
      </hierarchical-datasource>
      <checkboxes check-children="false" name="CheckedMonths" enabled="true" />
  </kendo-dropdowntree>

  <button type="submit">Save</button>
</form>

### Expected/desired behavior

When the DropDownTree TagHelper with checkboxes is used as a form editor, the values of the selected items must be submitted as expected to the server.

### Workaround

Use the HtmlHelper version of the DropDownTree

### 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".


### Environment

* **Telerik UI for ASP.NET Core version: 2023.2.606
* **Browser: [all]

Overview

Currently, the Telerik UI for ASP.NET Core Form wrappers does not expose an overload for passing Template Component via the ButtonsTemplate API configuration. In comparison to its ASP.NET MVC counterpart. E.g:

** HtmlHelper **
@(Html.Kendo().Form()
        .Name("form")
        .ButtonsTemplate(Html.Kendo().Template().AddHtml("<button>Submit</button>"))
)

** TagHelper **
<kendo-form name="formExample" action="Index" method="POST">
    <buttons-template>
        <kendo-button name="test">
            Some Test
        </kendo-button>
    </buttons-template>
</kendo-form>

It would be beneficial if the configuration accepts a Template Component overload similar to the ButtonsTemplate API in the MVC wrappers.

Current behavior

The Form Core wrappers do not expose a Template component option for the Buttons Template.

Expected/desired behavior

The Form Core wrappers should expose a Template component option for the Buttons Template.

### Bug report

The ContextMenu does not show when the mouse is moved normally. It will show only when the mouse is moved very slowly.

### Reproduction of the problem

1. Create a Grid with a custom column command.

2. Define a ContextMenu that will be displayed when the custom column command is clicked.

3. Click over a specified column command - the ContextMenu opens.

4. Move the mouse over another row and click the custom column command - the ContextMenu does not open.

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

### Current behavior

The ContextMenu does not open over every item as expected.

### Expected/desired behavior

The ContextMenu must open when clicking each item.

#### The issue is a regression starting with 2023.1.314 version

### Workaround

Add the following script before the ContextMenu initialization:

  <script>
    function contains(parent, child) {
        try {
            return $.contains(parent, child);
        } catch (e) {
            return false;
        }
    }

    kendo.ui.ContextMenu.fn.open = function (x, y) {
        var OPEN = "open",
            ACTIVATE = "activate",
            DOCUMENT_ELEMENT = $(document.documentElement),
            NS = ".kendoMenu";
        var that = this;

        x = $(x)[0];

        if (contains(that.element[0], $(x)[0]) || that._itemHasChildren($(x))) { // call parent open for children elements
            kendo.ui.Menu.fn.open.call(that, x);
        } else {
            if (that._triggerEvent({ item: that.element, type: OPEN }) === false) {
                if (that.popup.visible() && that.options.filter) {
                    that.popup.close(true);
                    that.popup.element.parent().kendoStop(true);
                }

                if (!that._triggerFocusOnActivate) {
                    that._triggerFocusOnActivate = that._focusMenu.bind(that);
                }
                that.bind(ACTIVATE, that._triggerFocusOnActivate);
                if (y !== undefined) {
                    var overflowWrapper = that._overflowWrapper();
                    if (overflowWrapper) {
                        var offset = overflowWrapper.offset();
                        x -= offset.left;
                        y -= offset.top;
                    }
                    that.popup.wrapper.hide();
                    that._configurePopupScrolling(x, y);
                    that.popup.open(x, y);
                } else {
                    that.popup.options.anchor = (x ? x : that.popup.anchor) || that.target;
                    that.popup.element.parent().kendoStop(true);
                    that._configurePopupScrolling();
                    that.popup.open();
                }

                DOCUMENT_ELEMENT.off(that.popup.downEvent, that.popup._mousedownProxy);
                DOCUMENT_ELEMENT
                    .on(kendo.support.mousedown + NS + that._marker, that._closeProxy);
            }
        }

        return that;
    };

Bug report

In a .NET 7 project when TagHelper Grid is configured and RuntimeCompilation is employed, starting from version 2023.2.606 an unhandled exception is thrown.

Reproduction of the problem

1. Create a .NET 7 project
2. Enable RuntimeCompilation
3. Install a 2023.3.606 or later version of Telerik UI for ASP.NET Core
4. Configure a TagHelper Grid

Current behavior

When run a runtime error occurs

Expected/desired behavior

TagHelper Grid should exhibit the same behavior as HtmlHelper ones.

Environment

• Kendo UI version: 2024.1.130
• Browser: [all]

Overview

Currently, the only way to nest conventional HTML tag content for the Template Component would be through the following configuration

@(Html.Kendo().Template()
    .AddHtml("<div>")
    .AddHtml("<p>Test</p>")
    .AddHtml("</div>")
)

It would be beneficial if the configuration accepts a delegate overload that would allow transpose the previous configuration to the following

@(Html.Kendo().Template()
    .AddHtml(@<text>
           <div>
                 <p>Some Value</p>
           </div>
    </text>)
)

Current behavior

Currently, the Template component does not expose a delegate overload for the .AddHtml() API configuration.

Expected/desired behavior

The Template component should expose a delegate overload for the .AddHtml() API configuration.

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?

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>

This is a strange bug I came across when making a simple grid for a small personal project. I created a class called Book, which looks like this:

[Table("Books")]
    public class Book
    {
        [Key]
        public int Id { get; set; }
        [Required]
        public string Title { get; set; } = null!;

        public Checkout? Checkout { get; set; }

        [NotMapped]
        public bool CheckedOut => Checkout != null;
    }

I then created a simple Razor view on which to show the books on a grid. Here is what the code for the page looks like:

@{
    ViewData["Title"] = "All Books";
}

@(
    Html.Kendo().Grid<LibraryMvc.Core.Entities.Book>()
        .Name("bookGrid")
        .Pageable(p => {
            p.PageSizes(new[] {20, 50, 100 });
            p.Numeric(true);
            p.Input(true);
        })
        .Editable(e => e.Mode(GridEditMode.InLine))
        .Filterable()
        .Sortable()
        .Scrollable()
        .ToolBar(t => t.Create())
        .Columns(col => {
            col.Bound(c => c.Id).Title("ID");
            col.Bound(c => c.Title).Title("Title");
            col.Bound(c => c.CheckedOut).Title("Checked Out");
            col.Command(com => {
                com.Edit();
                com.Destroy();
            }).Title("Manage");
        })
        .DataSource(ds => 
            ds.Ajax()
            .PageSize(20)
            .Model(md => {
                md.Id(f => f.Id);
                md.Field(f => f.Id).Editable(false);
                md.Field(f => f.CheckedOut).Editable(false);
            })
            .Read(r => r.Action("Book_Read", "Book"))
            .Create(c => c.Action("Book_Create", "Book"))
            .Update(c => c.Action("Book_Update", "Book"))
            .Destroy(c => c.Action("Book_Destroy", "Book"))
        )
)

When running my app with this code, I noticed that client-side validation would not work on the grid. Nothing would stop me from adding multiple Book rows with empty Titles, despite Title being a [Required] property based on my Book class's Data Annotations:

I assumed I did something wrong, so I scoured the internet and Telerik's support items in hopes of finding something, but then I came across this when inspecting the page's elements in Chrome's dev tools:

Look at the script tag. For whatever reason, the kendoTextBox ended up using the Razor view's ViewData["Title"] property. Oops!

To work around this, I ended up changing my Book class's Title field to BookTitle, as shown below:

[Table("Books")]
    public class Book
    {
        [Key]
        public int Id { get; set; }
        [Required]
        [Column("Title")]
        public string BookTitle { get; set; } = null!;

        public Checkout? Checkout { get; set; }

        [NotMapped]
        public bool CheckedOut => Checkout != null;
    }

With this property name changed, I was able to get client-side validation to work as needed:

A second workaround involved getting rid of the ViewData["Title"] definition on my Razor view:

Given all this, it looks like something that's generating the client-side validation on the page is getting tripped up over the word "Title" being used by multiple items on the page.

We can easily add a photo image with only face in it. 

The request is to add an option in the avatar to detect face from a full body image and auto zoom in to the face to create an avatar from the image provided. This can be controlled using an option in the avatar settings.
