Hi Team, 

I have found an issue in the Grid Component that I think needs some attention, see below.,

## Current behavior
My GridColumns are not styling correctly when i hide/show them based on an edit state (for example). Some that have no width restrictions will the shortened then not lengthed.

## Current Version

KendoReact 4.8.0

## Expected behavior
If I hide/show a GridColumn, its width should not affect other GridColumns, only the Grid overall.

## Minimal reproduction of the problem with instructions
Example: https://stackblitz.com/edit/react-ngpvuj?file=app%2Fmain.jsx

Instructions:
1. View how age is the only column visible with a width attr
2. Click "Switch Mode" and notice how 'Id' is not added, but a width of 80 is now applied to the 'lastname' column, the same width as age
3. Click "Switch Mode" back to view, and see how id is removed and a width of 60 is applied to the 'firstname' column.

## Investigation:
Some investigation in the DOPM revealed that the issue is centred around the <colgroup> of the Grid's <table>:
- step 2 does the following to the <col>s in the <colgroup>
  - add a new col to the beginning with a width, for the Id column
  - add a new col to the end with a width, for the Age column
  - DOES NOT clear the width of the col group that used to be the age column

- step 3
 - Simply removes the last <col> in the group. Does not affect hte attributes of the remaining <col>s

I hope this was informative and can be resolved soon.

Kind Regards,
Grant

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

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 :-)

The width of the Kendo React DatePicker can become small due to the container width.

In such case, consider the following use case

Users select the date part (year) and start incrementing it by the "up" key. The year date part is selected, but is partially visible,

and the users do not see the date part that they are currently modifying, while they can fully see the other date parts that are not currently in focus.

The DateInput needs a horizontal scrolling to ensure that a focused date part is fully visible to the users in case if the width of the component is narrow.

Please check the case here

https://stackblitz.com/edit/react-8dqy6j-gvgwtk?file=app%2Fmain.jsx 

DateTimePicker opens above or below the link to open it, however when it's in the middle of a page, it will choose to open below and sometimes require scrolling to see all the buttons.

Would be better, if it were to open offscreen, it should be "pinned" to the bottom edge.  Same for right/left/top borders of the screen.

Certain containers also make it impossible to scroll down to see the buttons, so that creates a real problem. The above proposal would fix this.

using fairly vanilla implementation of the component:

<DateTimePicker
      defaultValue={new Date(ActivationDate.toString())}
      onChange={handleActivationChange}
      width={'8rem'}
 />

Defined a date rang. But it allows to enter a date larger than a max date of the range. Both via calendar and manually.

const minDate = new Date(1, 1, 1);
const maxDate = new Date(9999, 12, 31);

          return (
           
              <DatePicker value = {this.state.value}
                 
                  min={minDate}
                  max={maxDate}
                
              /> 
           

There seems to be bug in the React Grid around date formatting inconsistencies:

Current behavior
When entering a date format of {0:dd/MM/yyyy} for a ColumnData prop, when in edit mode a calendar picker shows the date format as US date of MM/dd/yyyy.Expected behavior
The date should show as dd/MM/yyyy per the requested date format.Minimal reproduction of the problem with instructions
Create a Kendo grid with one column with following ColumnData:
const settlementDate: ColumnData = {
field: 'settlementDate',
title: 'Setlement Date',
format: '{0:dd/MM/yyyy}',
filterable: true,
filter: 'date',
editor: 'date'
};
Note that the date is displayed as MM/dd/yyyy
Change the format to "dd/MM/yyyy"
Note that when in view mode the date is displayed as "dd/MM/yyyy".
What is the motivation or use case for changing the behavior?
Currently I have to create a custom date cell for every instance of using a date field in my grid which is less than ideal.Environment

Other information:
It appears that there is an incompatibility as to what a text display field requires as opposed to what a date picker requires. For text display it requires a format of '{0:dd/MM/yyyy}' whereas the datepicker requires a format of "dd/MM/yyyy".

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.

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

The tooltip display position of KendoReact Chart  is incorrect

See the code.thank you

I am using the ComboBox component in IE11.  When the control has a value, the clear button covers the select arrow at the right of the control.  This occurs because IE11 does not allow nested calc() calls in the CSS width property, e.g. 

.k-dropdown-wrap .k-clear-value {
    right: calc(calc( 0.75rem + 17px) + 6.5px);
}

Removing the inner calc() works well enough:

.k-dropdown-wrap .k-clear-value {
    right: calc(( 0.75rem + 17px) + 6.5px);
}

Unfortunately, this rule seems to originate from a CSS function call to which I do not have access.  Is it possible to remove the inner calc()?

When rendering an AutoComplete, I get the following warning:

Warning: Failed prop type: Invalid prop `children` supplied to `Popup`.
    in Popup (created by ListContainer)
    in ListContainer (created by AutoComplete)
    in span (created by AutoComplete)
    in AutoComplete

I have tried this in the simple case below:

If you create a react grid without any GridColumn components and then add those components later, the added columns do not show and the grid is empty.  It appears, after a quick look that the columns have a width of 0 pixels.  They exist in the html, just not displayed.

See https://codesandbox.io/s/mmr894nllp as an example of the problem.  This example starts with a populated grid.  You can add columns and data using the buttons above the grid.  This works fine.  If you then "Reset" the grid with the button, which removes all data, any attempt to add columns and data will show a blank grid.

Thanks,

Joe

We are evaluating the React Grid component for our application and need to be able to have rows that span all columns.  To do this, I have created a rowRender function that, for some rows, will render a single <td> element with the colspan set to 100%.  The row renders fine, but the other rows, that have multiple <td> elements do not all render correctly.  For my test application, they will render with a width of 8 pxs.  On resize of a column, they will almost render correctly.

Here are some pictures of the issue in our test code.

I have created a sandbox that sort of reproduces the bug. https://codesandbox.io/s/w73v0x0mz8

If you select the "Show Full Row", the row with Id 999 will convert to a single <td> element with colspan='100%'.  You will notice how after doing so, the last three columns collapse to a small number of pixels.

Thanks

Joe
