Add a shared note property for the Chart.

This property should allow rendering a note for multiple series items similar to the shared tooltip funtionality.

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

Add more animation options to the KendoReact Chart rendering.

For example, we can add the following type of animation:

The new suggested animation type should change smoothly the Y values of the line, that is an animation of the line from its old points to its new points."

This should result in the lines (series) animating not the entire Chart.

MaterialUI exposes a `ListBoxComponent` prop on their dropdown components (https://material-ui.com/api/autocomplete/) it would be nice to have that exposed on the kendo multiselect as well.

Use cases include:

• simplifying styling
• Custom scroll bars for the dropdown

Hi,

I'm trying to validate the file names that are being uploaded using Kendo react Upload component. But the validation message I set is not displaying next to the file just the way the following messages are displayed.

File type not allowed.
Invalid file(s). Please check file upload requirements.
File size too large.
File size too small.

For reproducing the steps here is the code pen. If you try to upload any file which contains 2019 should show the validation error message.

Could you please consider this request as a new feature?

Hi Team,

I'm facing below issue when manually enter the value in the datepicker.

Control : DatePicker

 <DatePicker defaultValue={value} format="dd/MM/yyyy"  />

Step 1: Manually I'm trying to enter the data as 01/01/2021 and clicked outside the datepicker control ( now the focus is out of the datepicker ).

Step 2: Now try to change the date (day) by entering  "2".  (Our Expectation is system should display the date as 02/01/2021 instead it is appending the date and displaying as 12/01/2021)

Every time system is expecting the user to clear the existing value and then enter the new value. 

Can you take this as feature request. Value should not get append to existing value. It should overwrite.

Reference Ticket URL : https://www.telerik.com/forums/datepicker-when-user-enter-the-date-manually-the-value-getting-appended-with-the-previous-value

If this is taken as feature request when will it get delivered.

We have two issues with grid with virtual scroll.

Both are registered on github.

First one is really blocking us: https://github.com/telerik/kendo-react/issues/1010

Second one we found on Safari, it's also very critical for our customers: https://github.com/telerik/kendo-react/issues/1013

Version: 4.7.0. Please note that version specified in Additional information does not make sense as we use Kendo React not Kendo UI.

Can you help us somehow?

The ListView component has an item prop that allows you to specify the render component. That component receives ListViewItemProps. The ListViewItemProps type is not exported and cannot be properly imported elsewhere.

Hello,

The Form component does not allow me to submit unless I modify the initial values. We have a Form that is provided with initial values that may not need to be modified by the user first - the data is all valid and acceptable. The user, currently, would need to purposefully modify one of the Field values in order to get the Form to realize that it can be submitted.

I'm aware of the submit click event but that event does not perform any validation.

I believe there needs to be some middle area where the Form can be provided initial values and be allowed to submit without having to modify the form first.

I have created a code sample showing the scenario below ...

Thank you

Hi Team,

we are looking same property in Kendo Tree View React Version.

https://docs.telerik.com/kendo-ui/api/javascript/ui/treeview/configuration/dataspritecssclassfield

could you pls check the feasibility and add the same?

Hi,

I've got a large form I'm making. When the page the form is on first renders, I maker a server call and get back a large javascript object:

serverData = {id: "1", ClientID: "1423", EstSentDate: "2021-07-08", .... }. The date strings are ODCB standards for date strings.

The form displays the current values of all these fields. For all the other field types, I give the form the prop initialValues={serverData}, and if the field names match the object keys, it populates the field with the data nicely.

The datePicker is encountering an error though. It looks like it expects a Date object and not just a string. Is there something I can do within the DatePicker component, or the field containing it, to resolve this, without having to parse the entire data set I receive for all dates and convert them to Date objects, and feed that into a new object to pass to the form?

Being able to populate the entire form with the simple line initialValues={serverData} would be the best outcome for us.

Hello,

I am using tooltip component for a long desciption field in my grid cell. And I am using it as it will encapsulate Grid component (like the example below) as it is suggested in this page.

<Tooltip openDelay={100} position="right" anchorElement="element"> <Grid>... </Grid> </Tooltip>

My grid has a date field and I am using columnMenu for filtering (GridColumnMenuFilter). An error occurs when I hover the text of date field and says : 

Tooltip(...): Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.

I also trid to replicate the problem in the example on this page and it gives the same error. I forked the project and you can check it from https://react-ed5jns.stackblitz.io/

Simply move the cursor over month/day/year in a date filter area and see the problem. This seems like a bug. Or if there is any solution to this, I would like to see a workaround.

Thanks

Hi,

The Kendo React Form Handle Submit event provides complete data over all fields, even the unchanged ones. While this is good for traditional submits, we are building upon a REST service that has HTTP patch support,  wherein we intend to submit only those fields (properties) that have changed. 

While a deep compare with initialValues and handleSubmit data property is possible, we were wondering if the Kendo Form component itself has some property Or method that allows us to get the changed values only.  This will save us the deep compare efforts, time and issues, especially with forms that have hundreds of fields.   

If Kendo library has some deep compare method available, please do include that as well.

Kindly advise.

Currently the TileLayout will allow you to drag a Tile when you click and drag anywhere within the Tile. This doesn't combine very well with content within a Tile that might have click-and-drag functionality or even just click functionality. A small click within a Tile causes the Tile to visually "lift up" in preparation for dragging.

It'd be nice if there were a setting to enable dragging only on the Tile header portion or somewhere.

Currently I have to add a toggle somewhere on the page that disabled or enables dragging.
