### 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>

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

Image

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

Image

Current behavior

The returned newIndex is incorrect.

Expected/desired behavior

The returned newIndex should be correct.

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 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

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; }

  1. Bind a Grid column to the field.
  2. Set the default value in the DataSource:
.Model(model =>
{
    model.Id(p => p.OrderID);
    model.Field(p => p.OrderDate).DefaultValue(new DateOnly());
})
  1. Configure Popup editing in the Grid.
  2. 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 initialized in a hidden container (for example, in a non-selected tab of a TabStrip) and its initial data binding is disabled (autoBind: false), the pager information is not visible when the data is loaded afterward.

### Reproduction of the problem

1. Initialize a Grid into a non-selected tab of a TabStrip and set its autoBind option to "false".

2. Select the tab and check how the empty Grid is rendered.

3. Call the read() method of the Grid's DataSource in the browser console to request the data.

4. The data is loaded, but the pager information remains hidden.

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();
            })
        );
    });

### 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'} }"));

        .ServerPaging(true)
        .ServerFiltering(true)
        .ServerSorting(true)

  2. Click the "Export to PDF" button in the Grid's toolbar

Current behavior

Flickering caused by a scrollbar appearing and hiding

Expected/desired behavior

The Grid should remain unchanged during the export and no scrollbar should appear and hide during the export.
