Hello,

I am reading the documentation for Gantt, and if i understand it correctly i can customize header column (headerCell?), but I dont know how. Is there any examle ?

I wound like to customize the column with dates.

Thank you, Matjaz Reberc

Hi Team, 

###Current Behavior

When displaying checkboxes, they are not aligned for nodes with children vs. nodes without children

### Example

https://stackblitz.com/edit/react-rqvush?file=app/main.jsx

### Expected Behaviour

Nodes checkboxes should be aligned the same regardless of if they have children.

###Version

4.8.0

Thanks and Kind Regards,
Grant

Looking at the JSDoc for for `toDataSourceRequestString` and `toDataSourceRequest`, they both appear to have JSDoc above them, showing the parameter as:

 * @param {DataRequestState} state - The state that will be serialized.

Should this actually have `@param {DataSourceRequestState}`?

Given the simple example:

const RatingContainer = () => {
  const [ratingValue, setRatingValue] = useState(0);

  const clearRating = () => {
    setRatingValue(0);
  }

  const onRatingChange = (event) => {
    setRatingValue(event.value);
  }

  return <div>
    <Rating 
      value={ratingValue}
      onChange={onRatingChange}
    />
    <Button
      onClick={clearRating}
    >
      Clear
    </Button>
  </div>
}

export default RatingContainer;

The Rating component behaves as expected when updating `ratingValue` through the Rating component. However, when I want to clear the rating value with the 'Clear' button to update the `ratingValue`, the number of stars displayed doesn't update reflect the value of `ratingValue`.

Here is a subsection of my package.json file.

Issue #1

Given:

Controlled TextaArea componenet with autoSize and rows properties.

const App = () => {
  const [state, setState] = useState();

  return (
    <TextArea
      value={state}
      onChange={(e) => setState(e.value)}
      autoSize={true}
      rows={2}
    />
  );
};

When:

Add couple text lines to extend TextArea size and remove these empty lines in any way

Then:

Content from TextArea field is removed but TextArea height stays the same, doesn't come back to it's initial value. It's different comparing to example from your docs where example contains uncontrolled component.

Issue #2

Given:

Controlled TextaArea componenet with autoSize and rows properties.

const App = () => {
  const [state, setState] = useState();

  return (
    <TextArea
      value={state}
      onChange={(e) => setState(e.value)}
      autoSize={true}
      rows={4}
    />
  );
};

and styles like these

.k-textarea textarea {
  border: 1px solid blue;
}

When:

Start typing anything

Then:

Height of textarea component is decreasing

There is a bug when rendering nested `PanelBarItem` components into a `PanelBar`. This error began in version 8.0 and still exists in 8.2.0.

In the linked example sandbox, you can see that I am rendering an empty array of children and it causes an error. This used to not cause any issues.

An empty array is needed because we render some `PanelBarItems` that come from an AJAX query and so the children starts off as an empty array until the requests completes.

Title basically says it all. Issue can be easily observed in the basic Multiselect with virtualization example:

1. Open the dropdown
2. Scroll to the bottom end
3. Close the dropdown
4. Open it again - popup's scroll position is incorrect and therefore shows blank.

What seems strange is that I cannot reproduce this issue with the combobox virtualization, although I found a somewhat similar bug submitted for the combobox - https://github.com/telerik/kendo-react/issues/1450 

Hi team, 

Im my example (see here), I've added a 'name' attribute to the 'Persons' resource data, and changed the textField mapping to use the 'name' field, however the scheduler is still displaying the results of the 'text' attribute. 

Leading me to think that the scheduler is hardcoded to only look for the text attribute, because if its changed/removed, the scheudler does not display anything, regardless of what the 'textField' value is.

Please advise.

Thanks,
Grant

I would like to add two tables side by side in Telerik Editor two tables side-by-side like I would in google docs for ex:

Hi,

I would like to be able to specify a Grid Column template for the data without having to replicate the entire cell and its properties. Please see below for justification:

Consider the following example of KendoReact Grid Cell customisation: https://www.telerik.com/kendo-react-ui/components/grid/styling/#toc-adding-custom-cells

Following this approach results in the loss of a lot of properties from the grid cell compared with 'default' cells e.g.

<td colspan="1" class="" role="gridcell" aria-colindex="1" aria-selected="false" data-grid-col-index="0">Chai</td>
<td style="background-color: rgba(55, 180, 0, 0.32);">18 <span class="k-icon k-i-sort-asc-sm"></span></td>

These properties are important for many reasons including accessibility. There is another example of KendoReact Grid Cell customisation that preserves these properties here: https://www.telerik.com/kendo-react-ui/components/grid/cells/#toc-customization

e.g.

<td colspan="1" class="" role="gridcell" aria-colindex="4" aria-selected="false" data-grid-col-index="3">39</td>
<td colspan="1" role="gridcell" aria-colindex="5" aria-selected="false" data-grid-col-index="4" style="color: red;">false</td>

However, there is a considerable amount of code required to achieve this:

const CustomCell = (props) => {
  const field = props.field || "";
  const value = props.dataItem[field];
  const navigationAttributes = useTableKeyboardNavigation(props.id);
  return (
    <td
      style={{
        color: value ? props.myProp[0].color : props.myProp[1].color,
      }}
      colSpan={props.colSpan}
      role={"gridcell"}
      aria-colindex={props.ariaColumnIndex}
      aria-selected={props.isSelected}
      {...{
        [GRID_COL_INDEX_ATTRIBUTE]: props.columnIndex,
      }}
      {...navigationAttributes}
    >
      {value === null ? "" : props.dataItem[field].toString()}
    </td>
  );
};

I would like to be able to define a template for a cell without having to specify these properties every time.

Kind regards,

David

Hello,

We are encountering an issue with duplicate entries in our Kendo Grid with drag & drop functionality. When the grid is scrolled, clicking on any of the header cells multiple times results in the first entry being duplicated. This problem occurs on the example provided on your website as well: Kendo React Grid Row Reordering

Reproduction Steps:

1. Scroll down within the grid.
2. Click on any header cell multiple times.
3. Scroll back to the top of the grid.

You will notice that the first entry is duplicated multiple times. It appears that the reorder logic is being triggered when a header cell is pressed.

We are using version 6.1.0. Please refer to the attached video for a visual representation of the issue.

Thank you for your assistance.

This is a bug on your documentation website.

Go to https://www.telerik.com/kendo-react-ui/components/grid/ for example to see that the side panel on the left is empty in an Edge browser. It flickers then it disappears.

It works fin in Chrome and Firefox. 

Hi Support, 

Is there any org chat component or similar components in Kendo React that is similar to the Org Chart in this link https://demos.telerik.com/aspnet-ajax/orgchart/examples/overview/defaultcs.aspx?

Thanks & Regards,

Eason

As per the subject, you can no longer use the Calendar to select a date in a month before the currently selected Date. Please see the following demo:

https://stackblitz.com/edit/react-xc2oxm-wgsfhy?file=app%2Fmain.tsx

Steps to reproduce:

• Click on the Calendar button
• Click on any month before the currently selected month
• Click on any date in the month
• Observe that the day is changed correctly but the month is incorrectly incremented by one

This error is not observed if you:

• type in a date
• use the mousewheel to scroll to the earlier date instead of clicking on the month
• use Firefox instead of Chrome

We aren't certain but don't believe this error was present before the latest Chrome 113 update. The error is reproducible in all versions of KendoReact from 5.2.0 onwards.
