The `Surface` component, in the drawing module, has a few exposed event handlers. It exposes click, mouse enter and mouse leave. It does not expose a handler for mouse scroll wheel movement.

You can see the exposed handlers in the `SurfaceOptions` type ...

Can you please expose the mouse scroll event handler?

React v18 has been released.

It appears that KendoReact only supports up to v17 (dependency conflicts if you try to use v18).

Can you please add support for React v18?

Thanks!

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?

After updating the kendo version in my project to "^5.1.0" I've noticed that both grid pager dropdown and normal dropdowns won't close when clicked outside if the dropdown is opened using the arrow icon.

I've attached a video with the issue.

Is there any workaround for this?

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:

https://stackblitz.com/edit/react-vkzwzo?file=app%2Fmain.jsx

There is an inconsistency with the DateRange picker in the way element focus is set when closing the date selection popup by mouse vs keyboard. When using the mouse to close the date range selection popup, element focus becomes lost/reset.

You can simulate this from the example page https://www.telerik.com/kendo-react-ui/components/dateinputs/daterangepicker/

Steps to simulate good behavior (this works correctly):

* click the 'from' input text element (causes the popup to open and the text input to have focus)
* press 'escape' to close the popup (the popup is closed, and the 'from' input element retains focus)
* press 'tab' (focus moves to the 'to' text input element)

Steps to simulate behavior that could be improved:

* click or tab into the 'from' input element (causes the popup to open and the text input to have focus)
* click (with the mouse) outside the popup to close it (the popup is closed, and focus appears to be lost.)
* press 'tab' (focus moves to the 'from' input element again because we are back at the beginning of the tab order list)

This input can lead you into a tab order loop if you mix pressing 'tab' to advance focus, and using the mouse to click to close the date selection popup.
Feature request: when clicking to close the popup, element focus should be retained in the 'from' or 'to' text input; whichever had focus before the popup close, the same as pressing 'escape' to close the popup.

Hi,

I'm using GridColumnMenuCheckboxFilter in column that holds dates, but the dates shown within the GridColumnMenuCheckboxFilter are not formatted.

Is there a way to format the dates like dd/mm/yyyy?

Here is an axample: https://stackblitz.com/edit/react-4cxw2e?file=app/main.jsx

Thank you!

Hi,

The Telerik example for Inline Editing with Custom Editors uses a dropdown list with reference data hardcoded into the custom dropdown cell. This isn't a realistic scenario for for production code with dynamic reference data. If you pass the reference data for the dropdown to the custom cell then the dropdown loses focus every time you change the selected value. This can be seen by shifting the localizedData in the Telerik example referenced earlier from myDropDownCell.tsx to main and passing it as a parameter: https://stackblitz.com/edit/react-9ycz1i?file=app/main.tsx

Is there a workaround for this issue?

Kind regards,

David

Hi Team,

While navigating using keyboard tab key focus is not moving to multiple controls such as Bar graphs and legends in kendo React Charts.

Screen reader should narrate proper name, role and value for the controls.

NVDA Focus is not moving to the bar graphs and legends and it is not narrating proper value for the bar graphs and legends.

which includes following components

• Chart
• ChartArea,
• ChartSeries
• ChartSeriesItem
• ChartCategoryAxis
• ChartCategoryAxisItem
• ChartValueAxis
• ChartValueAxisItem
• ChartLegend
• ChartTooltip
• ChartSeriesItemTooltip

Can you please suggest if any,

Thanks & Regards,

Hi,

Using KendoReact Scheduler component the functionality to group the events by date, then by resources is not supported. I can only group them by resources first, then by date.
This feature exists in Kendo for jQuery Scheduler component and can be configured by setting the group.date property to true as following:

 group: {
    date: true,
     resources: ["Rooms"]
   }

resulting in something similar as in the picture below.

We need the same functionality in KendoReact Scheduler component as well.

Thanks,
Camelia

Hello

Currently, the KendoReact Grid can only select all columns as shown in this demo:

https://www.telerik.com/kendo-react-ui/components/grid/selection/#toc-customizing-the-selection

We wish to be able to select only specific columns programmatically. 

According to https://www.telerik.com/kendo-react-ui/components/installation/source-code/#toc-source-repository the repo should be updated nightly. However it does not seem to be.

Thanks for any help!

Currently, you cannot specify a custom icon for `MenuItem`, e.g. a Material Design icon, as the `icon` prop only accepts the name of an icon from the Kendo font icons.

So please can you add a `iconClass` prop just like Button so we are able to use an alternative icon set.

Thanks.

The Kendo Form component internally uses a FormContext which is ued by FormElement and Field. However this Context is not exported in @progress/kendo-react-form

Please export this context. It would really help with the usability of the Form component for complex forms. There are things in the FormContext that are not available in the formRenderProps.

Alternatively, put everything from the context into the FormRenderProps. These don't seem like they needed to be 2 different objects.

Specifically with the Context you can see what fields have been `touched`, `visited` and `modified`. But with the render props you only get a boolean if any field has been touched, visited or modified; not the names of the fields.

All of the Kendo components that "hide" content (tab views, collapse panels, etc) don't actually hide any content. They require us to not render any children.

<ExpansionPanel
  {expanded === item.id && (
    <ExpansionPanelContent>

This just strikes me as an odd design decision. I guess I don't understand the point of these components if they don't do the 1 thing they are supposed to do; hide portions of the content.

Un-rendering the content is usually not desirable. The contents are often still important. Possibly for SEO purposes, A11y, or if they are part of a Form:

<Form
  render={() => {
    <FormElement>
      <ExpansionPanel>
        {expanded === item.id && (
          <ExpansionPanelContent>
            <Field
                name={"firstName"}
                component={Input}
                validator={() => 'always invalid'}
              />
          </ExpansionPanelContent>
      </ExpansionPanel>
    </FormElement>
  }}
/>

This makes the Form valid as long as the panel is collapsed.

Can check out how Bootstrap collapse panels work to see how most people would expect these components to behave. The contents is rendered into the DOM and JS and CSS are used to hide it. There should be a way to achieve this same behavior with Kendo.

As a workaround I end up having to do my own CSS/SASS to hide the contents

.k-expander {
  .k-expander-content-wrapper {
    height: 0;
    overflow: hidden;
  }

  &.k-expanded {
    .k-expander-content-wrapper {
      height: auto;
    }  
  }
}

A few suggestions for the React Grid (as of v5.0.1) to help devs conform to accessibility compliance...

1) Standard HTML tables can contains a <caption> element, which screenreaders will use as the descriptive name of the table. Kendo Grid does not appear to have any way to name the table.

2) Related to number 1, other ways to assign a descriptive name to a table may be to include a `title`, `aria-label` or `aria-describedby` attributes, but none of these work on <Grid>. They are not rendered into the HTML if passed as props.

3) Allow GridCell and other Cell components to take `children` to render. The current documentation generally advises us to override the `cell={}` prop on a GridColumn for custom cell rendering. What is not listed in the docs is that doing what seems like the obvious thing:

<GridColumn cell={() => <td>myContent</td>} />

actually breaks accessibility. At a minimum the cell MUST get the attributes

            role={'gridcell'}
            aria-colindex={props.ariaColumnIndex}

to have the table actually be represented correctly in most screen readers. The Kendo <GridCell> component would normally add these, but only renders the field from the dataItem. It can only render custom data if the `render` prop is set, in which case it yet again does not render the `<td role= aria-colindex=` portions on it's own.

What I'm getting at is, everyone who ever wanted to render a custom cell in Keno Grid always had to make their own cell component that added at least the `role` and `aria-colindex` attributes, and if they didn't, they probably unknowingly broke accessibility.

Kendo could make this clearer in the docs (including the accessibility page for the Grid), and could easily alter GridCell to render `children` if they are passed. Then we could do:

<GridColumn cell={<GridCell><button>yay</button></GridCell>} />

and have the rendered HTML:

<td colSpan="1" style="" class="" role="gridcell" aria-colindex="1" aria-selected="false"><button>yay</button></td>

I think in GridCell this would be as easy as changing:

        defaultRendering = (
          <td
            colSpan={props.colSpan}
            style={props.style}
            className={className}
            role={'gridcell'}
            aria-colindex={props.ariaColumnIndex}
            aria-selected={props.isSelected}
            {...{[GRID_COL_INDEX_ATTRIBUTE]: props.columnIndex}}
            {...navigationAttributes}
          >
            {dataAsString}
          </td>

        defaultRendering = (
          <td
            colSpan={props.colSpan}
            style={props.style}
            className={className}
            role={'gridcell'}
            aria-colindex={props.ariaColumnIndex}
            aria-selected={props.isSelected}
            {...{[GRID_COL_INDEX_ATTRIBUTE]: props.columnIndex}}
            {...navigationAttributes}
          >
            {children || dataAsString}
          </td>

Feature request

I am using the `AutoComplete` component to implement a search input and I want to be notified when the user selects an item (via mouse click or keyboard navigation) from the popup list.

I found an undocumented prop `handleItemSelect` on the `AutoCompleteHandle` ref object, and used it to implement my feature successfully.

Please can you expose `handleItemSelect` as an event on the `AutoCompleteProps` API.

Hello, 

I'm trying to implement an accessible table using your Grid React component. The idea is for the users to be able to navigate the table using the keyboard if need be. Because we are a government contractor we have to make our product accessible and, testable using the Government issued tool for testing, ANDI. 

When I use a normal table, I can implement scopes in the table header, either for the column or the row and thus create relationships between headers and cells as well as, use the keyboard to navigate the entire table.

When the same table is implemented with the Grid component, there are no scopes in the header then again, both header and body are separate even though they reside inside a div with role=grid on it which in turn, contains two divs, one for the header and one for the body each in turn, implementing a table: one for what would be the headers and one for what would be the body. I'm attaching screenshots even though I'm sure you know the product.

The fact that both the <thead> and the <tbody> reside in different places, even though they are within the grid, makes it impossible to add associations furthermore, we're using a data-table and the grid. I tried using different props but, as long as both the header and the body are separate, the ANDI tools can't find the table.

Question is, is there a way to make this table truly accessible just as a one created using the semantic table tags?

Hi,

Unfortunately,  the KendoReact PivotGrid sorting is currently supported only for string values. This means that even if you set the field type to "date", the sorting will still be applied as if the field were a string. You can see that in this example: https://dojo.telerik.com/oZoTuMIC/55

Please extend your sorting mechanism so that the sorting covers types such as dates and numbers too. Please also consider the user's language when implementing this sorting. We receive date fields in the format yyyy-mm-dd and they should then be displayed in the user language in the UI. For example in German dd.mm.yyyy (i.e. 21.11.2021) or in English 11/21/2021. And please offer this feature for local data binding too.

Regards,

Oliver
