Hello, 

We have a project using kendo-angular with kendo-ui for jquery for some components (spreadsheet, gantt, datepicker, context-menu,..)

When we started the project we followed this doc https://www.telerik.com/kendo-angular-ui/components/framework/kendo-jquery/

I updated all our @progress/kendo-angular-xxx dependencies to latest versions and also kendo-ui to latest 2022.1.119

When I run the project with ng serve and the site starts, we directly have an error coming from kendo.colorpicker

Cannot read properties of undefined (reading 'options')     at kendo.colorpicker.js:279:181

I created an empty project with our dependencies and was able to reproduce the error. Please see attached zip file.

npm install  ->  npm run start   ->   http://localhost:4200/

Here the kendo dependencies we have:

"@progress/kendo-angular-buttons": "^7.0.2",
"@progress/kendo-angular-charts": "^6.0.0",
"@progress/kendo-angular-common": "^2.0.2",

Bug report
Window modal overlay missing when using KendoWindow that has the following configuration fo window1
{

modal: true,

draggable: {containment: "body"}

}

I aware that there is this forum talking about this issue, but the example is opeining both window without draggable.containment configuration.

The current easist workaround is dont set draggable.containment for window1

Reproduction of the problem
1. Run this dojo

2. Open window1, then open window2, close window2

3. The modal overlay for window1 dissapeared

Current behavior
When window1 has configuration for draggable.contaiment, its modal overlay will dissapear after window2 closed

Expected/desired behavior
The modal overlay for window1 should remain, closing window2 should not affect window1's modal overlay

Environment
Kendo UI version: 2021.2.616

1. Open parent directory in Tree View.

2. Click the child directory more than once. (Click 5 times in a row)

3. Show parent directory's position. (Create an infinite number of 'k-treeview-toggle' classes in the parent directory each time the child directory is clicked.)

• seems to affect all Themes

Bug report

When a culture that uses a "comma" as a decimal separator is applied to the Kendo UI NumericTextBox, the value of the aria-valuenow attribute uses the value without transforming the "," separator into a "." separator.

Reproduction of the problem

Set a culture that utilizes the comma as a decimal separator. Notice the aria-valuenow attribute's value:

Environment

* **Kendo UI version:** 2020.2.617
* **jQuery version:** 1.12.4
* **Browser:** [all] 

The interface for PromptOptions does not extend DialogOptions like it should. I added it into my definition file, and it compiles and works fine when testing.

    interface PromptOptions extends DialogOptions {
        name?: string;
        messages?: PromptMessages;
    }

The behavior of DropDownList, ColorPickers and probably more controls changes when a tooltip is added to them. When the tooltip opens, the ".k-state-border-down" CSS-class is added to the (e.g. DropDown) container. However, in the context of the DropDown, this class means that the DropDown is opened and therefore, the styling changes accordingly.

The following two DOJOs demonstrate this bug:

• Here, a DropDown without a tooltip works correctly: https://dojo.telerik.com/AvAxuQaK
• Here, a DropDown with a tooltip displays an unwanted shadow below the control: https://dojo.telerik.com/OGAVEzUb

We currently experience this behavior in the Editor widget when adding tooltips to tools that render the aforementioned controls.

Hello,

I've noticed that any attempt at calling `dataSource.read()` on a datasource attached to a Kendo Menu results in keyboard accessibility breaking.

Steps to reproduce:

1. Use this code as a starter: https://dojo.telerik.com/IJOyUzEX/2

2. Notice that tabbing to the menu works the first time 

3. Activate the menu and close it.

4. Now try to tab into the menu again. It does no longer work.

Are there any better methods to have Kendo Menu dynamically generate the list everytime an open event is triggered?

Hello,

in the Typescript bindings, the JQuery $("...").data("kendoXXX") Methods do not include undefined in there return values.

https://docs.telerik.com/kendo-ui/intro/widget-basics/jquery-initialization#duplicate-initialization

-> in the second script section, it is also documented that it can return undefined, when there is no widget instance found.

It also returns undefined, when the selector doesn't match any element.

Please include undefined in the return values.

I am trying to upgrade to jQuery 3.5.1 and as per the documentation regarding compatible KendoUI versions I have upgraded KendoUI to v2021.1.119 (R1 2021). Now even though this version is compatible, I am getting warning messages from jQuery Migrate plugin as follows:

Wondering if this issue is known and support for the issue is on its way. Or else is it reccomended to change the minified JS files as these seems to be simple fixes.

Thanks!

From the forum below.
Even if the axis type of category is other than "Date" (for example, character string / number), PlotBand's position at the time of panning
Please do not move the place.

Hi,

The `alwaysVisible` option is ignored when we have an external DataSource.

Consider the following code:

```

var dataSource = new kendo.data.DataSource({
   pageSize: 2,
   data: [
       { name: "Jane Doe", age: 30 },
       { name: "John Doe", age: 33 }
   ]
});

$("#grid").kendoGrid({
   columns: [
       { field: "name" },
       { field: "age" }
   ],
});
var grid = $("#grid").data("kendoGrid");

grid.setDataSource(dataSource);

grid.setOptions({
   pageable: {
       alwaysVisible: false
   }
});

```

Here, since the `pageSize=2` and we have `2` records; I don't expect to see not the pagination and other pager options after `alwaysVisible` is set to `false`.
However, I do see them since `alwaysVisible` is completely ignored.

When I move the datasource back inside the `$("#grid").kendoGrid({})` everything works as expected.

Please let me know if this is an bug or I have mistaken in understanding something about the options.

Thanks,

Ajay

Hi,

When I call grid.datasource.sync() on a datasource that has a model id defined, but this field is unmapped, I get a cryptic error. You can find a reproducer here: https://dojo.telerik.com/iLacazot

On a slightly related subject; When checking the docs on the model id it seems that the example is missing from this page:
