Bug report

The panelbar items for each level should have a span with "k-panelbar-item-text" and a "k-panelbar-item-icon" classes wrapping a given item's text and icon. Currently, the text is not wrapped in a span element, nor does it apply the required classes for both the items and icons.

Correct rendering for the items can be observed here. And the correct rendering for the icons can be checked here.

Reproduction of the problem

Inspect rendering of Panelbar items from this demo.

Current behavior

The PanelBar Item's TagHelper rendering lacks classes and a span wrapper element:

Expected/desired behavior

The Panelbar Item's TagHelper should have classes and a span wrapper element:

Overview

Currently, the ASP.NET Core Grid Columns's Template() method does not expose the ability to provide a delegate. In comparison to the ASP.NET MVC Grid Column's Template() method:

It would be useful to add this option to the ASP.NET Core Grid, as it will allow the configuration for multiline templates. For example:

.Columns(columns =>
{
    columns.Template(@<text>
        <div>#= OrderID # </div>
         <div>#= Discontinued # </div>
    </text>);
})

Current behavior

The Columns.Template() method of the Grid does expose a delegate overload.

Expected/desired behavior

The Columns.Template() method of the Grid should expose a delegate overload.

### Bug report

When the custom editor template of the Scheduler contains a label text with a special character, it is encoded automatically. If the encoding contains a hash literal (#), it throws a client-side error "Invalid template".

### Reproduction of the problem

1. Create a Scheduler with a custom editor template.

2. Add a label for a specified Model property by using the @(Html.LabelFor(model => model)) configuration.

3. Add a label text with a special character as per the example below.

<div class="k-edit-label">
    @(Html.LabelFor(model => model.Title, "Durchfüehrung"))
</div>

<div data-container-for="title" class="k-edit-field">
    @(Html.Kendo().TextBoxFor(model => model.Title)
        .HtmlAttributes(new  { data_bind = "value: title"})
      )
    <span data-for="title" class="k-invalid-msg"></span>
</div>

4. Try to add an event or edit an existing event. Open the browser console to review the error:

### Expected/desired behavior

The hash literals in the encoded strings should be escaped automatically.

### Environment

* **Telerik UI for ASP.NET Core version: 2023.2.718
* **Browser: [all]

I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.

At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.

What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:

I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode

I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.

Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.

### 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.
