Bug report

Even if a message file is added, the command buttons and the popup title in the Grid are not localized

Reproduction of the problem

1. Open the Dojo examples:

• Dojo with messages file - https://dojo.telerik.com/CehWjRrE
• Dojo with overriding the kendo.ui.Grid.prototype.options.messages - https://dojo.telerik.com/RWCxqxIm

2. Decrease the size of the screen so the Grid to be displayed in adaptive mode.
3. Click on a row and select the 'Edit' button to open the Edit popup

Current behavior

The command buttons and the dialog title are not localized:

Expected/desired behavior

It should be possible to change and localize the messages texts.

Workaround

 function onEdit(e){
      e.container.closest('.k-window').find('.k-window-title').text('My custom text')
      e.container.closest('.k-window').find('.k-button[ref-update-button]').text('Button Update Changed');
      e.container.closest('.k-window').find('.k-button[ref-cancel-button]').text('Button Cancel Changed');

### Bug report

When an Editor component in inline mode is set as an editor in an InCell editable Grid, the Grid cell does not enter edit mode on "click". The issue occurs since version 2023.1.314.

### Reproduction of the problem

1) Create an InCell editable Grid.

2) Set an Editor component in inline mode as an editor to a specified Grid column.

3) Try to edit the cell.

4) The cell flashes and does not enter edit mode.

A Dojo sample for reporduction: https://dojo.telerik.com/zQUvDQEq (check out the "ProductName" column)

### Expected/desired behavior

The Grid column that uses Editor component in inline mode must be editable.

### Environment

* **Kendo UI version: since 2023.1.314
* **jQuery version: 3.4.1
* **Browser: [all]

### Bug report

When using the default column checkbox filter menu and the data requested from the server takes time to load, the filter menu popup does not resize correctly when opening the menu for the first time.

The issue started to occur in version 2025.1.211.

### Reproduction of the problem

1) Enable the checkbox filter menu of a specified column. The Grid binds to remote data and the data operations are perfomed on the server.

2) Open the filter menu when the Grid is loaded.

3) The Read request triggers and a loader is displayed to indicate that the data is loading:

4) The options are loaded, but the popup container does not expand as expected:

5) Close the filter menu and opend it again:

### Expected/desired behavior

The filter menu popup must display all options when the data is loaded.

### Workaround

<style>
     .k-animation-container-shown {
        overflow: visible !important;
    }
</style>

### Environment

Bug report

When ParseFormats is set in the DatePicker editor used in the Grid popup, the picker does not show the field value to which it is bound.

Reproduction of the problem

1. Add a DateOnly? field to the model:

public DateOnly? OrderDate { get; set; }

2. Bind a Grid column to the field.
3. Set the default value in the DataSource:

.Model(model =>
{
    model.Id(p => p.OrderID);
    model.Field(p => p.OrderDate).DefaultValue(new DateOnly());
})

4. Configure Popup editing in the Grid.
5. Add a DateOnly.cshtml editor in EditorTemplates:

@model DateOnly?

@(Html.Kendo().DatePickerFor(m => m).ParseFormats(new string[] { "MM/dd/yyyy" }).HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("") }))

Current behavior

When editing a record. The value of the OrderDate field is not displayed in the DatePicker.
If you remove the ParseFormats option from the DatePicker, it shows the value as expected.

Expected/desired behavior

The field value should be displayed in the picker, even when ParseFormats is set.

### 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.

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

Bug report

The rowReorder event does not return the correct newIndex when dragging a row from a lower row index to a higher row index.

Reproduction of the problem

1. Run this dojo https://dojo.telerik.com/omyPpaZb
2. Drag Chai and drop after Chang. Note oldIndex is 0, newIndex is 2, which is unexpected as indices are 0-based

3. Re-run the dojo to start fresh and drag Chang and drop before Chai and the indices are correct - oldIndex: 1, newIndex: 0

Current behavior

The returned newIndex is incorrect.

Expected/desired behavior

The returned newIndex should be correct.

### Bug report

When opening the filter menu of a specified column through the classic ColumnMenu, the filter container is displayed with scrollbars when the dropdown of the filter operator is opened.

### Reproduction of the problem

1) Define a Grid and enable its classic ColumnMenu.

2) Open the filter menu of a specified column and then open the dropdown to select a filter operator.

3) The filter container has scrollbars. The "k-menu-popup" element has "overflow: auto";

Bug report

The Core Grid throws an exception when setting its toolbar template through the ClientTemplateId option. The issue is a regression introduced in version 2025.2.520.

Reproduction of the problem

1. Configure the toolbar of the Grid like this:

.ToolBar(toolbar => {
     toolbar.ClientTemplateId("myTemplate");
})

Current behavior

An exception is thrown:

NullReferenceException: Object reference not set to an instance of an object

Expected/desired behavior

The configuration works without throwing exceptions.

Wokraround

Use the alternative way of setting the toolbar template, on the Grid's root level:

@(Html.Kendo().Grid <MyModel>()
      .Name("grid")
      .ToolBarClientTemplateId("myTemplate")

Bug report

Expose additional API configurations for the Grid's ToolBar

Reproduction of the problem

As of recent releases, the Kendo UI Grid Toolbar has been substituted with the Kendo UI Toolbar. This change allows users to add the majority ToolBar.items API options apart from the built-in tools.

As noted within the Kendo UI for jQuery API documentation for the Grid's Toolbar:

"Apart from the built-in tools, the Grid fully exposes the ToolBar.items API. This way you can specify any custom tools in the widget using the components available in the ToolBar itself."

Current behavior

The inherited ToolBar.items API options are not available for the server-side Telerik UI Grid for ASP.NET Core and MVC wrappers as well.

Expected/desired behavior

It would be beneficial to the customers if the inherited ToolBar.items API options are available for the server-side Telerik UI Grid for ASP.NET Core and MVC wrappers as well.

Enhancement

Expose the sorts TagHelper for the Grid's column filter datasource taghelper

Overview

Currently, the Grid's Column Filter Datasource Taghelper exposes the following inner child TagHelpers.

Unlike its HtmlHelper counterpart which happens to expose the .Sort() API configuration. For example:

.Columns(columns =>
{
    columns.Bound(p => p.ShipName).Filterable(ftb =>
    {
        ftb.Multi(true);
        ftb.Search(true);
        ftb.CheckAll(true);
        ftb.DataSource(dataSource => dataSource
            .Custom()
            ...
            .Sort(sort =>
            {
                sort.Add("ShipName").Ascending();
            })
        );
    });
})
