Note: I already opened issue #7910 in the kendo-ui-core repo for this but wasn't sure if I should report this through the Feedback Portal.

The TextArea TagHelper does not render the "maxlength" attribute when set via data annotations.

Note: this is essentially the same issue from #6884 but applies to the TextArea helper (and not the TextBox helper), so perhaps the fix for that issue just needs to be applied to the TextArea helper (it's always that easy, right? 😉).

Given the following model property:

[StringLength(500)]
[DisplayName("Example")]
public string Example { get; set; }

The Kendo TextArea helper: 

<kendo-textarea for="Example" rows="3"></kendo-textarea>

...generates code without the "maxlength" attribute:

<textarea
   data-val="true"
   data-val-length="The field Example must be a string with a maximum length of 500."
   data-val-length-max="500"
   id="Example"
   name="Example"
   data-role="textarea"
   aria-disabled="false"
   rows="3"
   class="!k-overflow-auto !k-flex-none k-input-inner"
   autocomplete="off">
</textarea>

The default ASP.NET Core TextArea helper:

<textarea asp-for="Example" rows="3"></textarea>

...generates code with the "maxlength" attribute:

<textarea
   rows="3"
   data-val="true"
   data-val-length="The field Example must be a string with a maximum length of 500."
   data-val-length-max="500"
   id="Example"
   maxlength="500"
   name="Example">
</textarea>

The Kendo helper should generate the "maxlength" attribute like the built-in helper.

### 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;
    };

@(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" });
    })
)

### Bug report

The DropDownTree TagHelper does not serialize the "Value" and "Id" properties when it is configured for local data binding (using the "bind-to" option).

### Reproduction of the problem

1) Use the following DropDownTree TagHelper configuration:

//Controller
public IActionResult Index()
{
            List<DropDownTreeItemModel> ddtData = new List<DropDownTreeItemModel>()
            {
                new DropDownTreeItemModel() { Id = "1", Text = "Option 1", Value = "S1" },
                new DropDownTreeItemModel() { Id = "2", Text = "Option 2", Value = "S2",
                    Items = new List<DropDownTreeItemModel>()
                    {
                        new DropDownTreeItemModel() { Id = "3", Text = "Option 3", Value = "S3" }
                    }
                }
             };
            ViewBag.StateTreeListData = ddtData;
            return View();
}

// View
<kendo-dropdowntree name="StateLocationDropDownTree" style="width: 100%"
                    height="500px"
                    auto-width="true"
                    bind-to="(IEnumerable<DropDownTreeItemModel>)ViewBag.StateTreeListData">
</kendo-dropdowntree>

2) When the DropDownTree is loaded, inspect its initialization script - the "value" and "id" properties are "null".

### Expected/desired behavior

The "Id" and "Value" properties must be serialized as the rest of the DropDownTreeItemModel properties.

### Environment

### 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".

The options of the MultiSelect are not serialized when used in Template component.

### Reproduction of the problem

1. Open the following REPL sample: https://netcorerepl.telerik.com/mIOgYfFU47fvuM5N17

2. Review the MultiSelect that is initialized into the Grid's toolbar and notice that its options are not serialized.

### Current behavior

The Template component does not serialize the options of the MultiSelect.

### Expected/desired behavior

The Template component must serialize all options for the MultiSelect.

### Environment

Bug report

Toolbar.Items.Group.CustomTool() API of the Scheduler produces an invalid configuration.

Reproduction of the problem

1. Open the following Telerik REPL.
2. Try to add a Template component via the Toolbar.Custom.Items.Group.CustomTool() API configuration.
3. Notice that the configuration produces invalid serialization.

To give more context, the Toolbar's buttonGroup items do not expose, nor should they expose a template configuration. The currently available options advocate that each of the buttons must apply options similar to that of the ToggleButton.

Thus, making the wrapper configuration not applicable. The following dojo verifies this - https://dojo.telerik.com/@alexander64836/ayedUsAh

Current behavior

Toolbar.Custom.Items.Group.CustomTool() API configuration of the Scheduler produces an invalid configuration which is not serialized accordingly.

Expected/desired behavior

Toolbar.Items.Group API configuration of the Scheduler should expose a CustomTool() API configuration for the ButtonGroups.

Workaround

The current workaround would be to declare the CustomTool via the Toolbar.Custom.Items.CustomTool() API configuration. And a ButtonGroup via the Template component:

@(Html.Kendo().Scheduler<Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel>()
     .Name("scheduler")
     ...
     .Toolbar(t => t.Custom(c =>
         c.Items(itm => {
             itm.CustomTool(Html.Kendo().Template().AddComponent(c => c
                .ButtonGroup()
                 .Name("select-period")
                 .Items(t =>
                 {
                     t.Add().Text(string.Empty).Icon("chevron-up");
                     t.Add().Text(string.Empty).Icon("chevron-down");
                 })
             ));  
          })
       )
     )
)

The following Telerik REPL illustrates this approach.

### Bug report

When the deferred scripts are created, the script source points at the root of the application instead of the application's root directory.

### Reproduction of the problem

Enable the global deferred initialization and call the @(Html.Kendo().DeferredScriptFile()) method.

The rendered script tag is:  <script src="/kendo-deferred-scripts-XXXX.js"></script>

But it must be: <script src="/MyWebsite/kendo-deferred-scripts-XXXX.js"></script>

### Solution:

If you add a tilde in the Url.Content(), the generated script file must be located as expected:

public HtmlString DeferredScriptFile(string nonce = "")
{
           ...
            var scriptResult= hasDeferredScritps ? $@"<script src=""{urlHelper.Content("~/kendo-deferred-scripts-" + guid + ".js")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')}></script>" : "";
            var styleResult = hasDeferredStyles ? $@"<link href=""{urlHelper.Content("~/kendo-deferred-styles-" + guid + ".css")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')} rel=""stylesheet""></link>" : "";
            return new HtmlString(scriptResult + System.Environment.NewLine + styleResult);
}
