I am looking for added support for multi drag and drop and the ability to select multiple days as this is available in the jquery version:

Is it possible to define where the dropdown container (i.e. k-list-container) is appended in the DOM?

By default it is appended at the bottom of the body but I'd like to define where it is appended.

The reason why I need to do this is because I'm using the KendoReact components in a WebComponent (custom element) which is hosted in a shadow-dom for isolation.
The styles are also only loaded within the shadow-dom and are therfore not applied to content on the outside. 

The issue is that the kendo dropdown container is appended outside of the shadow-dom and the scope of the kendo styles.
The dropdownlist component is styled correctly but the dropdown part that is appended to body is not styled.

I've solved this with other components (i.e. modal window) by defining where I want the the container appended with the createPortal method in React.

          <ModalOverlay />
        document.getElementsByTagName('custom-element').length > 0
          ? document.getElementsByTagName('custom-element')[0].shadowRoot

          : document.body

I find the autogrow and floating labels in the latest Kendo Angular library to be quite handy:

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

See here:


We would like this as we need to distinguish between a change due to a user typing and a change due to a spin.

To hack around this we will probably need to create a DOM event on click on the spin buttons or something

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:




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.

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:


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.

Provide built-in scrolling of the Chart.

It should work similar to the pannable but allows scrolling with the mouse wheel instead of zooming.

The required end result is similar to this:

I would like to request a mode for the Kendo React Date and Time Inputs that would allow the use of a mask like that of the MaskedTextBox - allowing the user to type freely without having to make use the arrow keys for each individual date/time part.

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.

                    ref={(exporter) => { this._exporter = exporter; }}

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

We are currently evaluating the use of the Scheduler control but there are times using the calendar portion just doesn't make sense. I see there's a SchedulerForm exposed but using it displays a dialog where we'd like it to be an inline form. Having this form would prevent us from writing a custom one. Also, the ability to add custom fields with just the form and not the Scheduler is highly desirable.

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
Package versions:
@progress/kendo-base-component-react-wrapper@2019.2.606 deduped
@progress/kendo-ui@2019.3.1113Browser:Chrome (desktop) version 78.0.3904.108
Platform: Windows

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.

One thing we end up doing quite a bit of writing custom Kendo Form components. A lot of these seem like they could exist out-of-the-box. For example, it'd be nice to have a DropDownList as a Form Input, without having to code the custom component for it.

The scheduler component does not work in Internet Explorer. We need to support IE 11 for our costumers. On the Kendo React example page I get an error that the  'object does not support property or method 'entries'.  In the code we're developing the error is similar, but refers to 'forEach' instead of entries.

- provide a boolean property "virtualScrolling" on component GridColumnMenuCheckboxFilter which allows rendering a large list of filter options without delay


- https://www.telerik.com/forums/gridcolumnmenucheckboxfilter-virtual-scrolling

Use case:

- there are a lot of options to filter already in memory

- the filter dropdown has to open quickly (it opens slowly now, because there are so many options)

- after opening, the user sees a huge list (i.e. a long scrollbar)

- so he starts making the list of options smaller using the search input

Here's a screenshot with 100 options. 



From a developer point of view I think a scrollable filter is the most convenient way to handle the problem.

An alternative would be to provide a handler whenever the user selects a combobox in the GridColumnMenuCheckboxFilter. Then we could cut the number of options after a threshold and an option / combobox labelled "show more". When this is clicked, the filter options are re-rendered, the lists gets longer - and the user will get annoyed and will making the list of options smaller using the search input.

An other alternative would be to have a possiblity to force the user right away to use the search box. Instead of showing the list of checkboxes a text would be shown: "1258 options. Please refine your search input." But this would be a more invasive option.

Add parseFormats option to the KendoReact DateInputs (DateInput, DatePicker, DateTimePicker etc).

The option is expected to work as the parseFormats one available in Kendo UI:
