Bug report

The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.

Reproduction of the problem

1. Open this Dojo
2. Try to expand the Grid's groups

Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined

Current behavior

groupPaging is not compatible with the groupHeaderColumnTemplate

Expected/desired behavior

groupPaging and the groupHeaderColumnTemplate should be compatible

Environment

• Kendo UI version: 2021.2.616

• Browser: [all]

Bug report

When a Telerik UI Window is draggable and has its Position set, the first time the widget can be dragged, or it is being dispositioned while dragging.

Reproduction of the problem

1. Create a Telerik Window widget.

2. Set the Position.Left and Position.Top

3. Open and drag the window.

Expected/desired behavior

The window should be smoothly draggable.

Environment

* **Kendo UI version:** 2021.2.511
* **jQuery version:** 1.12.4
* **Browser:** [all]

IgnoreCase property is missing for the filterable options of the column:

https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI.Fluent/GridBoundColumnFilterableBuilder

The option is documented in:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.filterable.ignorecase

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

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.

### 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 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.

### Environment

* **Kendo UI version: 2022.1.412
* **jQuery version: 1.12.4
* **Browser: [all]

### 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
* **Browser: [all]

Bug report

Reproduction of the problem

1. Run this dojo: https://dojo.telerik.com/nuzVFAFI/6
2. Open the browser dev tools and clear the console.
3. Copy the table below the Editor and paste it in the Editor

Current behavior

An error for the missing image is thrown:
GET https://localhost:63252/test.png 404 (Not Found)

Expected/desired behavior

No error is thrown, since the value of the background-image property has been replaced with "none" in the Editor events and the actual content the Editor visualizes does not use the image:

<tr style="box-sizing: border-box; border-style: solid; border-width: 1px 0px; background-image: none;">
...
</tr>

Environment

• Kendo UI version: 2024.3.1015
• jQuery version: x.y

### Bug report

When deferring the component scripts to a file and a specified item of a Form HtmlHelper has a defined editor through the Editor() configuration, a client-side error is thrown:

"Uncaught Error: Syntax error, unrecognized expression: #"

### Reproduction of the problem

1) Enable the global deferred initialization.

2) Define a Form HtmlHelper with a ComboBox editor for one of its items:

@model FormViewModel

@(Html.Kendo().Form<FormViewModel>()
    .Name("form")
    .HtmlAttributes(new { action = @Url.Action("SubmitData", "Home"), method = "POST" })
    .FormData(Model)
    .Items(items =>
    {
        items.Add()
            .Field(f => f.Username)
            .Label(l => l.Text("Username:"));

        items.Add()
        .Field(f => f.City)
        .Label(l => l.Text("City"))
        .Editor(editor => editor
          .ComboBox()
          .DataTextField("Text")
          .DataValueField("Value")
          .BindTo(new List<SelectListItem>()
          {
            new SelectListItem() { Text = "City A", Value = "1" },
            new SelectListItem() { Text = "City B", Value = "2" },
            new SelectListItem() { Text = "City C", Value = "3" }
          })
        );
    })
)
@(Html.Kendo().DeferredScriptFile())

3) When the page with the Form is loaded, open the browser console and examine the error.  Review the content of the loaded kendo-deferred-scripts-xxxxx.js file - the ComboBox initialization script is included after the Form initialization script. Attached you can find screenshots.

When using the TagHelper version of the Form, the ComboBox initialization script is included in the kendo-deferred-scripts-xxxxx.js file before the initialization script of the Form with a unique generated "id" for example "3451ce77-2736-437f-9584-f5a5255902c2". In this case, no client-side errors occur.

### Expected/desired behavior

When deferring the component scripts to a file, the Form with specified editors must be initialized as expected without client-side errors.

### Workaround

Use the TagHelper version of the Form or define the editor by using the EditorTemplateView() option:

        items.Add()
        .Field(f => f.City)
        .Label(l => l.Text("City"))
        .EditorTemplateView(Html.Partial("ComboEditor"));

// ~/Views/Shared/ComboEditor.cshtml

@model FormViewModel

@(Html.Kendo().ComboBoxFor(m => m.City)
.DataTextField("Text")
.DataValueField("Value")
.BindTo(new List<SelectListItem>() {
	new SelectListItem() { Text = "City A", Value = "1" },
	new SelectListItem() { Text = "City B", Value = "2" },
	new SelectListItem() { Text = "City C", Value = "3" }
})
)
