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.

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

Bob

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.

The Kendo UI for jQuery TreeList provides options for configuring the settings of the Window when using Popup editing mode:

https://www.telerik.com/kendo-jquery-ui/documentation/api/javascript/ui/treelist/configuration/editable#editablewindow

Currently, the Window options are not available for the HtmlHelper and TagHelper TreeList. Is it possible to implement the Window() configuration of the Editable() option, as per the example below?

        .Editable(e =>
        {
            e.Mode("popup");
            e.Window(w => w.AppendTo("..").Animation(false).Draggable(false).Title("..."));
        })

### Bug report

When adding a <select> element as a custom tool in the Editor, the dropdown does not open.

### Reproduction of the problem

1) Run the Dojo sample and try to open the dropdown in the toolbar:

https://dojo.telerik.com/VVPUopDw

The same example work as expected with version 2023.1.117.

2) When using version 2024.4.1112, if you remove the "ref-toolbar-tool" attribute from the <div class='k-toolbar-item'> element, the dropdown opens as expected.

### Expected/desired behavior

The <select> element must function correctly when added as a custom tool in the toolbar.

### Workaround

Handle the "click" event of the select and prevent the event bubbling:

<script>
    $(function () {
        const selectElements = $('select[id^="symbolSelect_"]');
        $(selectElements).each(function (index) {
            this.addEventListener("click", clickHandlerSymbolSelect);
        });
    });

    function clickHandlerSymbolSelect(e) {
        e.stopPropagation(); //Prevent event bubbling, so Kendo cannot swallow or cancel the event.
        const sendingElement = e.target;
        sendingElement.showPicker();
        return true;
    }
</script>

### Environment

* **Kendo UI version: 2025.1.227
* **jQuery version: 3.7.1
* **Browser: [all]

### Bug report

When integrating components into the ToolBar by using the TemplateId() or TemplateView() options, the ToClientTemplate() option throws a client-side error "SyntaxError: Failed to execute 'appendChild' on 'Node': Unexpected token '<'".

When the component is added to the template without the ToClientTemplate() option, the component is rendered as expected in the ToolBar.

### Reproduction of the problem

A REPL sample for reproduction: https://netcorerepl.telerik.com/cTYqlaPG12psetl157

Remove the ToClientTemplate() option to observe how the DropDownList is rendered as expected.

### Expected/desired behavior

When using an external Kendo UI Template, any nested components must be defined with the ToClientTemplate() option.

### 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";

Use the following demo to test the case and select the "classic" type for the ColumnMenu: https://demos.telerik.com/kendo-ui/grid/column-menu

The issue does not appear when using version 2024.4.1112.

### Expected/desired behavior

The filter menu container must not change its appearance when the dropdown opens.

### Workaround:

<style>
.k-menu-popup {
    overflow: visible !important;
}
</style>

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")

Environment

• Kendo UI version: 2025.2.520
• Browser: [all]

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 using the Kendo MultiSelect TagHelper and binding it to a model property, the selected values are not populated.

Reproduction of the problem

Create the MultiSelect and bind it to a property of the view model:

@model API.Models.IndexViewModel

<kendo-multiselect for="SelectedCategoriesTagHelper"
                   bind-to="@Model.Categories"
                   datatextfield="Text"
                   datavaluefield="Value"
></kendo-multiselect> 

Expected/desired behavior

The MultiSelect TagHelper should correctly display the selected values when bound to a model property.

Hi Team,

Currently, Telerik.Licensing NuGet package only has target for netstandard2.0, netframework462 and net6.0. I cannot use .NET 6 for my .NET 9 application because .NET 6 is out of support. 

This is a feature request to either

• Remove the net6.0 TFM and reply only on netstandard2.0
  • or
• Add net8.0 and net9.0 targets.

Thank you,

Arthur

### Bug report

When loading a PDF file using the PDFViewer configured for DPL processing, the file content is loaded partially.

### Reproduction of the problem

1) Open the DPL Processing Demo: https://demos.telerik.com/aspnet-core/pdfviewer/dpl-processing

2) The file content is not loaded as expected.

The issue started to occur in version 2025.1.211. When comparing the responses of the "pdfviewer/getinitialpdf?pageNumber=1" request, the response when using the previous version (2024.4.1112) is longer than that of version 2025.1.211.

### Expected/desired behavior

The content of the loaded PDF file must be complete.

### Environment

* **Telerik UI for ASP.NET Core version 2025.1.211
* **Browser: [all]

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/eRazIrIB

1. Scroll the Grid

Current behavior

The data is requested, but it is not displayed in the Grid.

Expected/desired behavior

The data is displayed, regardless of the type of loader used.

Environment

### 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" }
})
)

Bug report

When enabling Editing for the Grid or TreeList a "No License" overlay is displayed in the following scenarios:

Reproduction of the problem

• Grid: overlay is displayed on load

@(Html.Kendo().Grid<TelerikMvcApp13.Models.OrderViewModel>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.OrderID).Filterable(false);
        columns.Bound(p => p.Freight);
        columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
        columns.Bound(p => p.ShipName);
        columns.Bound(p => p.ShipCity);
        columns.Command(c => c.Edit());
    })
    .Editable(e=>e.Mode(GridEditMode.PopUp))
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Model(m=>m.Id(o=>o.OrderID))
        .Read(read => read.Action("Orders_Read", "Grid"))
        .Update(read => read.Action("Orders_Update", "Grid"))
        .Create(read => read.Action("Orders_Create", "Grid"))
        .Destroy(read => read.Action("Orders_Destroy", "Grid"))
    )
)

• TreeList: initially there is no overlay. Clicking on "Edit" button shows overlay and "No License" popup.

@(Html.Kendo().TreeList<Kendo.Mvc.Examples.Models.TreeList.EmployeeDirectoryModelPopUp>()
    .Name("treelist")
    .Toolbar(toolbar => toolbar.Create())
    .Columns(columns =>
    {

        columns.Add().Width(300).Command(c =>
        {
            c.CreateChild().Text("Add child");
            c.Edit();
            c.Destroy();
        });
    })
    .Editable(e => e.Mode("popup"))
    .DataSource(dataSource => dataSource
        .Create(create => create.Action("Create", "EmployeeDirectory"))
        .Read(read => read.Action("All", "EmployeeDirectory"))
        .Update(update => update.Action("Update", "EmployeeDirectory"))
        .Destroy(delete => delete.Action("Destroy", "EmployeeDirectory"))
        .Model(m =>
        {
            m.Id(f => f.EmployeeId);
            m.ParentId(f => f.ReportsTo);
            m.Expanded(true);
            m.Field(f => f.FirstName);
            m.Field(f => f.LastName);
            m.Field(f => f.ReportsTo);
            m.Field(f => f.HireDate);
            m.Field(f => f.Extension).DefaultValue(0);
            m.Field(f => f.Position);
        })
    )
    .Height(540)
)

Expected/desired behavior

No overlay and popup should be displayed in case of valid license.
