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?

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.

### 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

* **Kendo UI version: 2025.2.520
* **jQuery version: 3.7.1
* **Browser: [all]

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.

Environment

• Kendo UI version: 2025.2.520

Currently, if a PDFViewer is opened on a mobile device and we use two fingers to zoom its content, the file is zoomed but the more we zoom it, the blurrier its content becomes. The reason for this is the fact that when we use "pinch-zoom" to zoom the PDF file(in a PDFViewer) it is zoomed using the browser's zoom functionality and not the functionality provided by the PDFViewer component. 

It will be a very useful feature if the built-in PDFViewer zoom functionality is used when the user zooms content with two fingers, on a mobile device

Description

File Manager refresh changes the selected item.

Refresh should not change the selected item if it is available after refresh.

If the selected item is not available after refresh, Preview pane should show No File Selected.

Reference

https://demos.telerik.com/aspnet-core/filemanager

Error

Select Documents folder in Tree View then Excel Document in List View. Excel Document is shown in the Preview pane.

Refresh the File Manager using jQuery in Console.

$("#filemanager").getKendoFileManager().refresh()

Excel Document is not selected and Preview pane shows Documents.

Refresh changed the selected item.

Expected behavior

Selected file does not change after refresh.

Example Windows File Explorer. Select a file in the folder and press F5 to refresh the folder.

Description

FileManager calls Create and Destroy instead of Update on move.

That is not what happens in the file system. Move is Update operation where the location of the item is updated. No files are copied or deleted.

Copying files and directories unnecessarily wastes the resources on the server and the cloud where computing and storage operations are charged.

If Destroy fails which might happen because Create and Destroy are executed separately then files are copied and not moved.

Expected behavior

Move calls Update.

### 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]

1. Installs both extensions ASP.NET Core and MVC without the latest MVC and ASP.Net Core product versions
2. Create an ASP.NET Core project with an older version
3. An Update Available Notification appears for ASP.Net Core
4. Click on the "Update Now" button
5. The Upgrade project wizard is launched
6. Click on "Next" button, then the following error appears:
   
   

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.

Environment

• Kendo UI version: 2024.1.130

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.
