Currently, the DatePicker can be set to read-only mode by adding the "readonly" attribute through the HtmlAttributes() option or by calling the client-side readonly() method.
Is it possible to implement a built-in Readonly() option, so the DatePicker is initialized as read-only? For example:
@(Html.Kendo().DatePickerFor(m => m.StratDate)
.Readonly(true)
)
> PivotGridV2 local flat-data binding produces identical values for all measures when multiple field-based measures are defined
---
**Description:**
When using **PivotGridV2** with local flat data (`.BindTo()` / inline `data` option) and defining **multiple measures that each reference a different numeric field**, all measures resolve to the same aggregated value instead of summing only their designated field.
### Environment
- Telerik UI for ASP.NET Core (2025 Q2 / latest)
- .NET 10
- Tested in Chrome, Edge
### Steps to Reproduce
1. Define a flat data model with multiple numeric properties:
```csharp
public class PivotRow
{
public string Category { get; set; }
public int Revenue { get; set; }
public int Units { get; set; }
}
```
2. Configure PivotGridV2 with two measures on separate fields:
```csharp
.Schema(schema => schema
.Cube(cube => cube
.Dimensions(d => { d.Add(m => m.Category).Caption("Category"); })
.Measures(measures =>
{
measures.Add("Total Revenue").Field(m => m.Revenue).AggregateName("sum");
measures.Add("Total Units").Field(m => m.Units).AggregateName("sum");
})
)
)
.Measures(measures => measures.Values("Total Revenue", "Total Units"))
```
3. Bind to local data containing rows where Revenue ≠ Units (e.g., Revenue=5000, Units=3).
### Expected Behavior
Each measure column aggregates **only its own field**:
- "Total Revenue" sums only the `Revenue` property
- "Total Units" sums only the `Units` property
### Actual Behavior
**All measure columns display the same value.** Both "Total Revenue" and "Total Units" show the same number. The pivot engine appears to ignore the `field` property on each measure definition during aggregation, summing the same (first?) numeric field for every measure.
### Key Observations
- The serialized cube schema is correct — each measure has the proper `field` mapping:
```json
{
"Total Revenue": { "field": "Revenue", "aggregate": "sum" },
"Total Units": { "field": "Units", "aggregate": "sum" }
}
```
- The underlying `PivotCubeBuilder.process()` method (used by `PivotDataSource` v1) **does** produce correct per-measure values when invoked manually with the same data and configuration.
- The bug is specific to **`PivotDataSourceV2`** — the v2 pipeline does not pass the per-measure field context through to its internal aggregation path, causing all measures to resolve identically.
- A single measure (e.g., only "Total Revenue") works correctly. The bug only manifests with **2+ measures referencing different fields**.
### Workaround
We implemented a monkey-patch on `PivotDataSourceV2.fn._saveState` that intercepts the rendered cell array and recalculates each cell's value from raw data using the measure's `field` property and tuple member filters. This confirms the issue is isolated to the v2 data source aggregation pipeline — the grid rendering layer correctly displays whatever values `_saveState` provides.
### Attached
Full `.cshtml` page demonstrating the issue (with workaround patch included for reference).
According the the documentation a user should be able to use the keyboard to navigate out of the spreadsheet as deescribed here. However, this does not happen.
Steps to reproduce:
- Open the Dojo - https://dojo.telerik.com/IvdWHNwo/2
- Navigate or click in the last cell in the last row
- Click Tab key.
Current behavior: The focus remains in the same cell.
Expected behavior: Teh second input should be focused.
The issue is a regression starting with version 2024.4.1112
### Bug report
When the virtualization is enabled, in some cases, the selected options in the dropdown do not match the selected options in the input.
### Reproduction of the problem
1) Create a MultiSelect with Virtualization (for example, the same configuration as in the online demo).
2) Select multiple options from the dropdown.
3) Enter a search entry in the input to filter the displayed options and select a specified option.
4) Scroll down and select another option.
5) Remove some of the already selected options through the input.
6) Open again the dropdown. The selected options in the input do not match the selected options in the dropdown.

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
The MCP assistant server currently supports Visual Studio, Visual Studio Code and Cursor.
Provide official support for Claude Code as well:
However, I do not see a way to handle when the tab strip is closed.
### Bug report
The Menu flickers on page load (i.e., when reloading the page, when navigating through the application pages).
### Reproduction of the problem
Attached is a demo that replicates the issue.
### Expected/desired behavior
The Menu should be rendered smoothly.

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)
)
Hey,
It would be very useful if the TimePicker component would have a feature called something like "AutoFocusTime()". By default, when there is no value inside the TimePicker, the default focused time is "12:00 am", therefore the user has to scroll up all the way to the required time. With the feature above, it would be possible to enter a time which should be focused by default. For example "8:00 am" which is when most businesses start operating.
Now the question is, why not just putting in a default value. Well, in a form with lots of inputs, the user may not know anymore which values he entered and which inputs have a default value set and therefore submitting wrong data. If a input doesn't have a default value this mistake can be caught by setting a [Required] attribute. Threfore, the user has to enter a value and it will be guaranteed that all values where entered by him and it wasn't a default value which has been set.

</script>Reproduction of the problem:
https://netcorerepl.telerik.com/myurdlbI16kA1TM213
Current behavior:
There is no way to have a dynamic template for column commands that depends on datasource.
Expected/desired behavior:
Having column-command template as column template, making it possible to access data from datasource.
Environment:
Kendo UI version: 2024.2.514
Workaround:
As an alternative solution, I'm using data-bound event, performing a for loop to all rows, but it needs to go line by line, which is not the best solution for large data.
Maybe adding it to the Kendo UI .Net Core offering would at least entice us to sign up for that too!
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?
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.
