Hi,

  we have a feature request as per description, value isn't changed when manually entering numbers in the field, it only changes when selecting a presented date. When manually entering date, value remains null so reset is actually changing null to null, not the entered value to null. Your colleague mentioned that the feature of exposing mask to be controlled would make it possible to clear the mask.
Please refer to this github issue for more detailed information, containing stackblitz example and gifs of an user case, as it was an ongoing discussion.
Please implement an option to properly reset partially entered dates.

Hi there, 
Im use chart component, and  sometimes the tooltip on grid disappear, i dont know why, and if i put the same code on the telerik this bug doesnt happen, here is an exemplo with the same data 

import * as React from 'react'
import * as ReactDOM from 'react-dom'

import {
    Chart,
    ChartSeries,
    ChartSeriesItem,
    ChartCategoryAxis,
    ChartCategoryAxisItem,
    ChartTitle,
    ChartLegend,
    ChartTooltip,
    ChartValueAxis,
    ChartValueAxisItem
} from '@progress/kendo-react-charts';

import 'hammerjs';


	const valueAxis = [
		{
			name: "",
			format: "{0:n1}",
			font: "10px Roboto",
      
		},
	];


const seriesValues = [
		{
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 1",
			spacing: 1,
      data: [27869.8616],
		},
		{
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 2",
			spacing: 1,
      data: [13277.95],
		},
		{
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 3",
			spacing: 1,
      data: [95164.9968],
		},
		{
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 4",
			spacing: 1,
      data: [115579.184],
		},
    {
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 4",
			spacing: 1,
      data: [null],
		},
        {
			type: "bar",
			toolTipFormat: "{0:n2}",
			title: "Teste 4",
			spacing: 1,
      data: [616.7145289747288],
		},
	];

const ChartContainer = () => (
  <Chart>
      <ChartTooltip
    shared={true}
    />
 <ChartValueAxis>
    {valueAxis.map((e, idx) => (
      <ChartValueAxisItem
        key={idx}
        name={name}
        labels={{
          visible: e.visible !== undefined ? e.visible : true,
          format: e.format,
          rotation: "auto",
          font: e.font,
        }}
      />
    ))}
  </ChartValueAxis>
    <ChartSeries>
      {seriesValues.map((item, idx) => (
        <ChartSeriesItem
          key={idx}
          type={item.type}
          data={item.data}
          name={item.name}
          spacing={item.spacing}
          labels={{
            font: '10px',
            format: "{0:n2}"
          }}

                />))}
    </ChartSeries>
  </Chart>
);

ReactDOM.render(
  <ChartContainer />,
    document.querySelector('my-app')
);

I inspected the page and realized this, that div is the tooltip and thats working normally, k-animation-container-show class, top and left properties on style;

and this one, is the tooltip that doest appear in the screen, does not have all class and style, just doesnt show up, 

However, the component inside that div was rendered, as can you see

Im using this version

Hi there,

I can see there is a column chooser component for the Angular Data Grid e.g. https://www.telerik.com/kendo-angular-ui/components/grid/columns/menu/#toc-column-chooser-item but there is not an equivalent for the React Data Grid (unless you code it yourself).

The DevExpress React Grid does have this feature https://devexpress.github.io/devextreme-reactive/react/grid/docs/guides/column-visibility/ so we were wondering if such a thing is planned React Data Grid?

Thanks very much,

James

On this page: https://www.telerik.com/kendo-react-ui/getting-started/

There's a syntax mismatch in end-of-line semicolons.

This line ends with a semicolon:

```js
import '@progress/kendo-theme-default/dist/all.css';
```

This line does not end with a semicolon:

```js
import { Calendar } from '@progress/kendo-react-dateinputs'
```

All teams that I know of consider it to be an error to do both ways in the same file.

The solution is to pick one way then be consistent. The broader solution is to use a linter, such as ESLint, that can process the code to ensure you're using your expected syntax and formatting.

In the case of multiple columns headers, the column width of the KendoReact  TreeList  is invalid

Hi,

I was just running through the new features of KendoReact 2021 R2 and am very keen to start implementing.

One of my colleagues pointed out that there is an ellipses after each checkbox when using checkboxes under Grid Selection, see https://www.telerik.com/kendo-react-ui/components/grid/selection/#toc-customizing-the-selection). It sees this is the casein MS Edge and Chrome. I use Firefox, so didnt notice it.

Thanks for the new features, keep it up.

Regards,
Grant

A TimePicker control will take all scroll events if the mouse cursor is over it, whether the element has focus or not, and prevent the scroll from bubbling up to the page. This prevents a page from scrolling as soon as the mouse cursor touches a TimePicker.

Using Kendo rect v5.1.0 in FireFox v98 on OSX. (Issue does not happen in Chrome)

You can view the problem in the demo page: https://www.telerik.com/kendo-react-ui/components/dateinputs/timepicker/
Just try to scroll down the view, and as soon as the TimePicker is under the mouse cursor, the page can no longer be scrolled until you move the cursor off the control.

Set up a TimePicker with a `min` and `max`. For example

            min={new Date(0, 0, 0, 0, 0)}
            max={new Date(0, 0, 0, 5, 0)}

Click on the text input to focus the 'hours' portion.

Roll the mouse scrollwheel up/down to change the hours.

You can 'scroll' past 5:00 and set the time to anything above the max.

You can also use the keyboard to enter any number outside the min/max.

Is this the expected behavior? Do we always have to add our own validation to check the min/max ourselves?

Add render prop for the SplitButton.

This will allow changing the main button and also the button that opens the DropDownList.

I use a Datepicker with 'he' loclae. It works fine, but the week's days are displayed from left to right instead of right to left as expected.
I tried to add className = 'k-rtl' but it did not help.
Is there a way to change that?

Here is a demonstration of the problem:
