### Bug report

The ExpandAll() option does not expand or collapse the TreeView nodes.

### Reproduction of the problem

1. Enable or disable the ExpandAll() option.

2. The nodes are not expanded/collapsed when the TreeView is initialized.

A REPL sample for reproduction: https://netcorerepl.telerik.com/mSuMEPkZ10ZA6l8P00

### Expected/desired behavior

All nodes must be initially expanded when ExpandAll(true) is set.

### Environment

* **Telerik UI for ASP.NET Core version: 2024.2.514
* **Browser: [all]

Bug report

The Visible() API configuration is not applied correctly in the TreeView.

Reproduction of the problem

1. Open the following Telerik REPL example.
2. Set the Visible() API configuration to a given TreeView Item explicitly to false and notice that the item is not hidden.

Current behavior

The Visible() API configuration is not applied correctly.

Expected/desired behavior

The Visible() API configuration should be applied correctly similar to how the Menu wrapper:

Environment

• Kendo UI version: 2023.3.1114
• jQuery version: x.y
• Browser: [all]

Bug report

The TreeView rendering in UI for ASP.NET MVC and UI for ASP.NET Core are not consistent. Setting the Id configuration for an item in UI for ASP.NET MVC renders a data-id attribute, that is missing in UI for ASP.NET Core.

Reproduction of the problem

1. Use the following TreeVIew definition

@(Html.Kendo().TreeView()
        .Name("treeview-kendo")
        .TemplateId("treeview")
        .Checkboxes(c=>c.CheckChildren(true))
        .Items(treeview =>
        {
            treeview.Add()
                .Text("My Documents")
                .Id("MyId1");

            treeview.Add()
                .Text("My Documents 2")
                .Id("MyId2");                
        })
)

Current behavior

When using the UI for ASP.NET Core the rendered <li> element does not have the data-id attribute that is present in UI for ASP.NET MVC

<li role="treeitem" class="k-item k-treeview-item k-first" data-uid="a3c937fd-1c4a-46a6-81e1-e53e1a2aeb6e" aria-checked="false" aria-selected="false" aria-expanded="false" data-expanded="false" aria-setsize="2" aria-level="1">
  <div class="k-treeview-top k-treeview-top">
    <span class="k-checkbox-wrapper" role="presentation">
      <input id="_a3c937fd-1c4a-46a6-81e1-e53e1a2aeb6e" aria-hidden="true" type="checkbox" tabindex="-1" class="k-checkbox k-checkbox-md k-rounded-md">
    </span>
    <span class="k-treeview-leaf k-in">
      <span class="k-treeview-leaf-text">My Documents</span>
    </span>
  </div>
</li>

Expected/desired behavior

Rendering should be consistent and the data-id attribute added in UI for ASP.NET Core.

Workaround

Use the HtmlAttributes configuration to add the data-id attribute

treeview.Add()
    .HtmlAttributes(new {data_id = "MyId1"})
    .Text("My Documents")
    .Id("MyId1");

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]
• Further details available in ticket 1588455

### 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
