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.
### Bug report
When adding custom classes or styles to the TimeDurationPicker component, they are applied to the hidden input elenent rather than to the parent element.
### Reproduction of the problem
1. Create a TimeDurationPicker and add a class to its element:
<input id="timedurationpicker" class="testClass" />
2. When you inspect the component's markup, the "testClass" is added to the hidden input element.
A Dojo sample for reproduction: https://dojo.telerik.com/IsTnGqsk
### Expected/desired behavior
Any custom attributes must be added to the parent element with class "k-timedurationpicker".
### Environment
* **Kendo UI version: 2025.2.520
* **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.
### Environment
* **Telerik UI for ASP.NET Core version: 2025.2.520
* **jQuery version: 3.7.1
* **Browser: [all]
### Bug report
When the TreeList is set up for Popup editing, the "required" validation triggers immediately when the Popup form is opened.
### Reproduction of the problem
1) Create a Popup editable TreeList.
2) Add the DataAnnotation [Required] attribute to any of the Model properties.
3) Click the built-in "Add new record" command.
4) The editor of the required field is automatically focused and the validation triggers immediately.
The behavior can be observed in the TreeList Popup Editing demo: https://demos.telerik.com/aspnet-core/treelist/editing-popup
### Expected/desired behavior
The validation must trigger on blur, as in the jQuery demo.
### Environment
* **Telerik UI for ASP.NET Core version: 2025.2.520

Expose additional API configurations for the Grid's ToolBar
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."
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.
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.
### Bug report
When using the sort" and "filter" toolbar commands, the "sort" and "filter" events do not trigger.
### Reproduction of the problem
A Dojo sample for reporduction: https://dojo.telerik.com/ySEQTSSS
### Expected/desired behavior
The "sort" and "filter" events must trigger when sorting and filterng the columsn through the respective toolbar commands.
### Environment
* **Kendo UI version: 2025.2.520
* **jQuery version: 3.7.1
* **Browser: [all]
### Bug report
The "Clear Sorting" and "Clear all filters" labels cannot be localized when using the "sort" and "filter" toolbar commands.
### Reproduction of the problem
A Dojo sample for reporduction: https://dojo.telerik.com/JHJGUaSH
### Expected/desired behavior
The "Clear Sorting" and "Clear all filters" messages should be exposed for localization.
### Environment
* **Kendo UI version: 2025.2.520
* **jQuery version: 3.7.1

Hi Team,
I noticed there is an Azure Blob Storage example with the UI for ASP.NET Core Upload, but there is not an example with Chunk Upload. I would like to request an example be provided in your documentation.
Thank you!
Hi Team,
I would like to request to add an Html/Tag Helper for the kendo.ui.icon.
Thanks!
Currently, when exporting a file from the Spreadsheet that contains named ranges, which refer to invalid or missing references (e.g., "#REF!"), the exported file is corrupted when attempting to open it in Excel:
Is it possible to remove any invalid named ranges before exporting the file to avoid such a warning when opening the file in Excel? Alternatively, rewrite the invalid named ranges in the exported file, so they are ignored by Excel when opening the exported file.
By default, when opening a file with invalid named ranges in Excel, there is no automatic warning to the user.
I'm in the process of rewriting all Kendo components to use CSP compatible templates. I'm looking at https://docs.telerik.com/aspnet-core/html-helpers/template/overview which shows how we'd use TemplateComponentName() for popup editors and that we would need to rewrite everything in the popup editor to use Kendo Template's AddHtml or AddComponent methods.
Original:
<div class="mb-2 row required">
@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
<div class="col-sm-6">
@(Html.Kendo().TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
</div>
</div>
<div class="mb-2 row">
@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
<div class="col-sm-6">
@(Html.Kendo().TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
</div>
</div>
Rewritten:
@(Html.Kendo().Template()
.AddHtml("<div class='mb-2 row required'>")
.AddHtml(@<text>
@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
</text>)
.AddHtml("<div class='col-sm-6'>")
.AddComponent(c => c.TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
.AddHtml("</div></div>")
.AddHtml("<div class='mb-2 row'>")
.AddHtml(@<text>
@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
</text>)
.AddHtml("<div class='col-sm-6'>")
.AddComponent(c => c.TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
.AddHtml("</div></div>")
)
While this works, this markup seems much harder to read than the original. Could this be made to be simpler? Ideally I'd like to be able to drop my existing mix of html and kendo components in one method and it'd parse through to render the template properly.
### 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

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.
