### Bug report

When building the scripts with NPM, there is syntax error "Unexpected number":

### Reproduction of the problem

Build the scripts (version 2025.3.812).

### Expected/desired behavior

The scripts must be built successfully.

### Workaround:

Remove the extra single quotes that wrap the version in the "rollup.mjs.config.mjs" and "rollup.modules.config.js" files:

• rollup.mjs.config.mjs

import glob from 'glob';
import path from 'path';
import { nodeResolve } from '@rollup/plugin-node-resolve';
import polyfill from 'rollup-plugin-polyfill';
import alias from '@rollup/plugin-alias';

...

const version = '2025.3.812';

• rollup.modules.config.mjs

import glob from "glob";
import path from "path";
import { nodeResolve } from "@rollup/plugin-node-resolve";
import polyfill from "rollup-plugin-polyfill";
import alias from "@rollup/plugin-alias";

...

const version = '2025.3.812';

### Environment

* **Kendo UI version: 2025.3.812

### Bug report

When the Grid is set up for OData-v4 binding, the columns that bind to DateOnly fields fail to filter. The date value in the filter expression contains the time portion and the following error is thrown:

"The binary operator GreaterThan is not defined for the types 'System.Nullable`1[System.DateOnly]' and 'System.Nullable`1[System.DateTimeOffset]'."

### Reproduction of the problem

1) Create a Grid that uses OData-v4 binding.

2) Bind a specified column to a DateOnly field.

3) Filter the column through the default column filter menu and open the browser DevTools to review the response of the request.

//Model
public DateOnly LastProdUpdate { get; set; }

//View
@(Html.Kendo().Grid<ProductViewModel>()
    .Name("grid")
     .Columns(columns =>
        {
            columns.Bound(p => p.LastProdUpdate).Format("{0:dd/MM/yyyy}");
        })
        ...
        .Filterable()
        .DataSource(dataSource => dataSource
        .Custom()
        .Type("odata-v4")
        .Transport(t =>
        {
            t.Read(read => read.Url("/odata/Products").Data("function() {return {'$expand': 'Employee'} }"));
        })
        .PageSize(10)
        .ServerPaging(true)
        .ServerFiltering(true)
        .ServerSorting(true)
     )
)

### Expected/desired behavior

The DateOnly fields must be filtered successfully as the DateTime fields.

Currently, the Content function for Steps in a Wizard only accepts a string value (see API here). 
This means that in order to add a partial view (bound to the current model and its properties), the most straightforward way I could find was to put the partial view (and any wrappers) in its own file and add an extension method "ToHtmlString()". For example:

@model MyModel

@(Html.Kendo().Wizard().Steps(step => {
    step.Add().Content(Html.Partial("~/Path/To/View/Wrapper.cshtml", Model).ToHtmlString());
})

using Microsoft.AspNetCore.Html;
using System.IO;

public static class HtmlContentExtensions
{
    public static string ToHtmlString(this IHtmlContent htmlContent)
    {
        if (htmlContent is HtmlString htmlString)
        {
            return htmlString.Value;
        }

        using StringWriter writer = new();
        htmlContent.WriteTo(writer, System.Text.Encodings.Web.HtmlEncoder.Default);
        return writer.ToString();
    }
}

@model MyModel

@(Html.Kendo().TabStrip().Items(tabstrip => {

    tabstrip.Add()
    .Content(@<div id="@Model.TabContainer" class="myTabWrapperClass"> 
       @await Html.PartialAsync("~/Path/To/View.cshtml", Model)
    </div>);

})

Is it possible to implement an option that enables the paging of the Grid View?

For example:

@(Html.Kendo().FileManager()
    .Name("filemanager")
     .Views(gridView => gridView.Grid(grid => grid.Pageable()))
     ...
)

### Bug report

When loading an editor through a partial View using EditorTemplateView(await Html.PartialAsync("PartialViewName")), the following error occurs:

The 'await' operator can only be used within an async lambda expression. Consider marking this lambda expression with the 'async' modifier.

### Reproduction of the problem

@(Html.Kendo().Form<UserViewModel>()
     .Name("myForm")
     .Items(items =>
     {
         items.Add().Field(f => f.Username).EditorTemplateView(await Html.PartialAsync("PartialViewName"));
      })
)

### Expected/desired behavior

The EditorTemplateView() must accept Html.PartialAsync("PartialViewName").

### Bug report

When setting autoWidth: true and expanding a node, the popup's width is not adjusted based on the displayed child nodes.

### Reproduction of the problem

1) Enable the autoWidth option and open the DropDownTree.

2) Expand an item. A horizontal scrollbar appears and the width of the popup is not adjusted as expected:

A Dojo sample for reproduction: https://dojo.telerik.com/faeuFFwb/2

### Expected/desired behavior

The width of the popup must be automatically adjusted when expanding an option and the "autoWidth" option is enabled.

### Bug report

When dragging and dropping a file into a specified FileManager folder, the Upload request triggers twice.

### Reproduction of the problem

1. Open the FileManager Demo: https://demos.telerik.com/kendo-ui/filemanager/index

2. Open the browser's Network tab.

3. Drag and drop a file into the FileManager.

4. Two Upload requests are triggered one after another.

### Expected/desired behavior

When uploading a single file with drag & drop, a single Upload request must trigger. When using the default upload button to upload a file, a single request triggers as expected.

### Environment

### Bug report

When defining custom editors in the OrgChart form by using EditorTemplateView() or EditorTemplateId() options, the editors are not initialized as expected.

### Reproduction of the problem

1) Define a DropDownList editor in a partial View and load it through the EditorTemplateView() option:

@(Html.Kendo().OrgChart<OrgChartEmployeeViewModel>()
                .Name("departmentsChart")
                .Editable(edit =>
                {
                    edit.Form(form => form
                      .Items(i =>
                      {
                         i.Add().Field(x => x.ParentDepartment).EditorTemplateView(Html.Partial("~/Views/Shared/EditorTemplates/ParentDepartmentDropDown.cshtml"));
                      }));
                })
                ...
)

// ~/Views/Shared/EditorTemplates/ParentDepartmentDropDown.cshtml
@model OrgChartEmployeeViewModel

@(Html.Kendo().DropDownListFor(m => m.ParentDepartment)
    .OptionLabel("-None-")
    .DataTextField("Text")
    .DataValueField("Value")
    .DataSource(source =>
    {
	    source.Read(read => read.Action("ReadDepartments", "Home"));
    })
)

2) The DropDownList is not initialized when opening the OrgChart form.

### Expected/desired behavior

The editors defined through the EditorTemplateView() or EditorTemplateId() options must be initialized correctly.

### Environment

* **Kendo UI version: 2025.2.520

Bug report

TimeDurationPickerFor does not work in EditorTemplates scenarios.

Reproduction of the problem

1. Create a TimeDurationPickerFor Helper within a standalone view within the ~/Views/EditorTemplate/ folder.

@model double

@(Html.Kendo().NumericTextBoxFor<double>(m => m))

2. Use the Editor template within a more compound component. E.g the Grid

        .Columns(columns =>
        {
            columns.Bound(m => m.Duration).EditorTemplateName("TimeDurationPicker");
            columns.Command(command => command.Edit());
        })

3. Notice that the application produces a server error.

Current behavior

The TimeDurationPickerFor Helper does not work in EditorTemplates scenarios.

Expected/desired behavior

The TimeDurationPickerFor Helper should work in EditorTemplates scenarios.

Environment

• **Kendo UI version: 2025.2.702

The FileManager triggers two Read requests when double clicking a folder in the ListView/GridView. The behavior can be observed in the Basic Usage Demo.

When navigationg to a folder in the TreeView using a single click, the component triggers a single Read request.

Could you consider optimizing the request handling when navigating to nested folders, particularly in ListView/GridView, to reduce redundant Read calls and improve performance?

Hi,

I'm following this document to load data into the grid view control using local data binding.

https://demos.telerik.com/aspnet-core/grid/local-data-binding 

I'm not sure this is an issue or expected grid view behavior when using local data binding. If loader-type and no-records are added. What happens is when there are no records, the Skeleton is still displayed and the no-records template is not displayed (see the attached image)

<kendo-grid mobile="Disabled" name="Grid" loader-type="GridLoaderType.Skeleton">
 <columns>
 <column field="ProductName" title="Product Name">
 </column>
 <column field="UnitPrice" format="{0:C}" title="Unit Price" width="130">
 </column>
 <column field="UnitsInStock" title="Units In Stock" width="130">
 </column>
 <column field="Discontinued" title="Discontinued" width="130">
 </column>
 </columns>
 <datasource type="DataSourceTagHelperType.Ajax" page-size="20" server-operation="false" data="@Model">
 </datasource>
 <filterable enabled="true">
 </filterable>
 <scrollable enabled="true" />
 <pageable enabled="true">
 </pageable>
 <sortable enabled="true" />
<no-records template="string HTML template, automatically centered" />
</kendo-grid>

Thanks

Currenty, when the Grid is in InCell edit mode, if a column binds to a boolean field, it is required a custom logic to display the field as a checkbox, which is always in edit mode and can be updated through a single click. Here is a REPL sample that shows the example:

https://netcorerepl.telerik.com/GJOhEIkj47P2xHf709

My opinion is that this functionality should work correctly out of the box without additional coding. If this is not available, then there should be an applicable sample code.

Is it possible to make an example where EF, Dirty works, no double click required and the checkbox always looks like a checkbox?

As stated in the title, the Save() action of a grid (with pagination, not endless scroll) does set the scroll position to the top instead of persisting it. 

I tried to follow instructions from https://www.telerik.com/aspnet-core-ui/documentation/html-helpers/data-management/grid/scrolling/overview#restoring-the-scroll-position but without success. The scroll position is moved to the top after the DataBound event handler.

Starting with version 2025.2.520, the toolbar tools like "Save changes" and "Cancel changes" are hidden by default. When the ShowInactiveTools(true) option is set, the inactive tools are displayed as disabled until a change in the Grid's data is made (for example, the tools are active when the edited cell is closed).

Is it possible to create an option that enables the previous behavior of the inactive toolbar tools - to keep the tools always active and visible no matter if there is a change or not?

For example:

.ToolBar(toolbar =>toolbar
            .Items(itm =>
            {
                itm.Create();
                itm.Save();
            })
            .EnableInactiveTools(true)
)

Hello, 

I have a treeview that is getting the first items which are locations, then it loads divisions as its children. I want to have the treeview load a top item called "Locations" that is static. It will need to be expanded and load all the locations under it. Then when I click on a location it loads the divisions. The locations and divisions will be populated by a call to the controller and action. I have yet figured out how to do this and is it even possible? Here is the code I have right now. You will see for now that I am loading a div with the location icon and "Locations" as the text, but I would like this to be the top root level of the treeview.
