I have a need for the 'Drop files here to upload' text to always be visible in the drop area of the KendoReact Upload component. Example of what I am talking about is in attached images.

When using the tab strip, it'd be nice if there were an event that fired before the tab changed so that we could abort a tab chat. For example, if a tab has some input fields that allow a user to change some setting but they change the tab without hitting save or something. It'd be nice if I could pop up a modal and ask them to save before changing tab.

The function could just return true or false to allow the tab change, etc.

UPDATE: This is live code I prepared for you: https://stackblitz.com/edit/react-ts-dhhsaz?file=index.tsx

I get error:

 Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app

But error appears to be inside KendoDrawer component. I can't figure out what is wrong. This is my component:

import React, { useState } from 'react';
import { withRouter, useLocation, useHistory } from 'react-router-dom';

import { Drawer, DrawerContent } from '@progress/kendo-react-layout';
import { Button } from '@progress/kendo-react-buttons';



export const SidebarDrawer = (props:any) => {

    const items = [
        { text: 'Povezivanje', icon: 'k-i-inbox', selected: true, route: '/povezivanje' },
        { separator: true },
        { text: 'Notifications', icon: 'k-i-bell', route: '/notifications' },
        { text: 'Calendar', icon: 'k-i-calendar', route: '/calendar' },
        { separator: true },
        { text: 'Attachments', icon: 'k-i-hyperlink-email', route: '/attachments' },
        { text: 'Favourites', icon: 'k-i-star-outline', route: '/favourites' }
    ];

    const [expanded, setExpanded] = React.useState(true);
    const [position, setPosition] = React.useState(true);
    const [selectedId, setSelectedId] = React.useState(items.findIndex(x => x.selected === true));

    let positionMode = position ? 'start' : 'end';

    const handleSelect = (ev:any) => {
        setSelectedId(ev.itemIndex);
        setExpanded(false);
    };

    const handleClick = () => { setExpanded(prevState => !prevState); };

    const handleChange = () => { setPosition(prevState => !prevState); };

    const drawerProps = {
        expanded: expanded,
        position: positionMode,
        mode: 'push',
        items: items.map(
            (item, index) => ({ ...item, selected: index === selectedId })),

        onSelect: handleSelect,
    }

    return (
        <Drawer {...drawerProps}>
            <DrawerContent>
                {props.children}
            </DrawerContent>
        </Drawer >
    );

};

export default withRouter(SidebarDrawer);

And this is how I use it inside App component:

import React, { useState } from 'react';
import { hot } from 'react-hot-loader';
import { Button } from '@progress/kendo-react-buttons'
import { Grid, GridColumn, GridDetailRow, GridToolbar } from '@progress/kendo-react-grid';
import '@progress/kendo-theme-bootstrap/dist/all.css';

import 'bootstrap/dist/css/bootstrap.min.css';
import { Drawer, DrawerContent } from '@progress/kendo-react-layout';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

import urlConstants from 'ClientApp/constants/urlConstants'
import { Connecting } from '../containers/connecting/Connecting';
import SidebarDrawer from 'ClientApp/components/SidebarDrawer/SidebarDrawer';

export const App: React.FC = () => {


    return (
        <React.Fragment>
            <Router>
                <SidebarDrawer>
                    <Switch>
                        <Route exact={true} path="/" component={Connecting} />

                    </Switch>
                </SidebarDrawer>
            </Router>
        </React.Fragment>
            )
}

export default hot(module)(App);

Hi,

I need to implement two functionality for treelist control

1. Freezing of column and rows

2. Drag and Drop column and rows

Hi,

I'm seeing a bug in TreeList which seems to be related to how locked column positions are being set.  The issue I'm seeing is when I scroll to the right the columns either overlap of have a gap between them.  See image below.

I also created a demo that demonstrates this issue: https://stackblitz.com/edit/react-lwp4ua?file=app%2Fmain.jsx

Seeing this issue in:

Hello,

Please allow the Form component to submit even if it's not marked as modified internally. I am trying to use the Form within a Stepper workflow, and the Form can have default values based on what they submitted in the previous Step. If they return to the Step with the Form on it, though, and those initial values are not changed while displaying the Form, then the Form internally is not marked as modified, therefor the submit event never fires.

It'd be nice if we could have a boolean to tell the Form if we care to block submission based on modified or not.

Thank you

Hello,

I have a query regarding multiple cell paste and transpose paste

1. Multiple cell pastes:

Mouse selection of multiple cells after selecting, the contents present in the cells should get copied and while pasting it should get paste in multiple cells.
e.g i) column no 3 and 4 having value 200 and 56700 after selection of this  value gets copied while pasting into column no 3 and 4,250 and 3250 replace by copied value
      ii) column no 3 and 4 having value 200 and 56700 and next row value i,e 250and 3250 after selection of this  value gets copied while pasting into column no 5, so the           values 2400,98250,6750,34500 replace by copied values

2.Transpose Paste:

Mouse selection of two or more cells, then the contents present in that cells should get copied then after clicking on transpose paste the copied cell content get pasted vertically in multiple cells.

e.g column no 3 and 4 having value 200 and 56700 after selection of this  value gets copied while pasting into column no 3,250 and 300 replace by copied value

all cells should be editable

I am trying to lock first column in Grid, when I used the instructions in Kendo React documentation I tried the same but as you see in screenshots it's not working.

We need to customize our exported excel to contain some additional information to the top rows of the excel sheet.

On using 'filterable' option as true in ExcelExport React component, it's getting applied on the first row but we want those filters to come on header values present on the 2nd/nth row in case we have some additional information on the top rows.

<ExcelExport
                    data={data}
                    fileName="Products.xlsx"
                    ref={(exporter) => { this._exporter = exporter; }}
                    filterable={true}
                >

Please refer the attached snapshots for actual and expected results needed from customization.

When using the <Window> component, there is an issue trying to maximize, when a parent element has positioning (ie:  position: absolute, position: relative).  The calculation for defining the width uses window.innerWidth (similar for height).  However, for placement, it uses top and left = 0.  

You can see a sample of this on StackBlitz:

https://stackblitz.com/edit/react-59kqss

This is a straight copy of https://www.telerik.com/kendo-react-ui/components/dialogs/window/controlled-mode/, but added the additional styles to the parent <div>.

Version is 3.14.

Thanks.

With the ArcGauge component, when you set the rangeLineCap to something other than 'butt' (ie:  round or square), the indicator does not line up with the tick lines.  This leads to misleading values.  Please look at this StackBlitz:

https://stackblitz.com/edit/react-itztql

This will show the comparison between round and butt rangeLineCaps. 

From the screenshot as well, the ArcGauge on the right looks like the value is greater than 0, resulting in the user being mislead on the result.

Hi,

I have Scheduler vertical timeline with an user group and more users I add the wider is every slot.  Example 2 users https://stackblitz.com/edit/react-dttghr?file=app%2Fmain.jsx . Example 4 users https://stackblitz.com/edit/react-dttghr-a3nor3 the slot is double in width in comparation with 2 users. Can I control this somehow?

Hello,

After taking a look at your example in the documentation here (which doesn't seem to be working) https://www.telerik.com/kendo-react-ui/components/charts/chart/elements/selection/#using-selection-as-navigator 

I fixed the onSelectEnd function and got it working. However, the selection chart is reloading the data every time onSelectEnd changes this.state.min and this.state.max.

Here is the example:

https://stackblitz.com/edit/react-nub1sc?file=app/main.jsx 

As you can see, this makes for a clunky UI.

If this isn't a bug, do you have suggestions on how to fix this?

Thanks,

Orla

1. Configure a Kendo React Grid with paging on a react-bootstrap tab that is hidden on initial load
2. Navigate to the tab - the Grid is rendered with truncated paging controls and no item count
3. Resize the screen in any way - the full paging controls and item count are restored

Is there a workaround for this issue?

I would like to use my custom component as the chat input. Is it possible to add new prop to chat component? Similar to DatePicker's "dateInput" prop.

The navigation sidebar smooth scroll animation doesn't work for the Calendar component.

Here is a codesandbox that showcases the issue: https://codesandbox.io/s/hopeful-river-sk4oc?fontsize=14&hidenavigation=1&theme=dark

Thanks in advance for fixing this :-)

Hi there!

I've written this component for a custom message input box for the Chat in Conversational UI for React:

import { ChatMessageBoxProps } from '@progress/kendo-react-conversational-ui'
import { FC } from 'react'

const CustomChatMessageBox: FC<ChatMessageBoxProps> = (props) => {
  return (
		<>
			<input
				type="text"
				name="message"
				className="h-full w-full text-base md:text-sm focus:outline-none"
			/>
			{props.sendButton}
		</>
  )
}

export default CustomChatMessageBox

I'm supplying this component to the `messageBox` prop of the Chat component. However, sending the message doesn't work; neither by pressing enter or pressing the send button. If I replace the input with props.messageInput, it works.

Any help in fixing this will be greatly appreciated!

Thank in advance :-)
