Number format in schema model field

HI,

I have a Kendo UI spreadsheet control bound to a datasource. I need to format the currency fields within to include a thousand separator as follows 13,000,000. How is this possible in the schema/model/fields. Here is my code:

schema: {
model: {
id: "ItemId",
fields: {
ItemAmount: { type: "number", format: "#,#" }
}
}
}

This doesn't work and the number is displayed as 13000000

[Solved] Pivot Grid Datasource, can JSON be used?

I'm struggling to get a Pivot Grid to populate. The demo works fine locally; however the datasource for it is XML from the datacube/dll. I have been using other widgets successfully with data delivered as JSON; is it possible to use JSON for the Pivot Grid? Are there any examples of this or even other examples of a Pivot Grid aside from the demo? Thanks in advance.

kendo grid column header - aria-haspopup

Hi Team,

Kendo grid column has "aria-haspopup=true" even though there is no popup/submenu that can be opened from the header.

there are no column filters or column menus present in this example.

sample dojo

also see attached image where it shows the aria-haspopup attribute.

thank you

Gantt: Issue creating new task after editing existing one

Hi,

So when working with the Gantt timeline I came upon a weird issue.

I have a simple view in which I enabled editing the title directly in the tree view.
When I click the 'add task' button after loading the page it works without issues. A new item will be added to the end of the list like it should.

After double clicking into any task and changing the title, this button does not really work anymore.
For some reason the menu, that usually only shows up, when an entry is selected, will appear.
Clicking 'add above' or 'add below' only produces console errors since there is obviously no item selected (see attached image).

It makes no difference if the task has been modified using the dialog or by double clicking the title in the left pane and editing it there.

This behavior also occurs in the linked dojo using the latest Kendo version (2021.2.616)
https://dojo.telerik.com/uBAHUgOy

In our project I temporarily solved it by re-selecting the entry in the save event listener but I think this is a more general issue with the gantt timeline.

save: function (data) {
    window.setTimeout(()=>{
     $timelineArea.data("kendoGantt").select('tr[data-uid="' + data.task.uid +'"]')
}, 500)
},

Thanks in advance for helping comments

[Solved] DatePicker - Date text disappears when using next/prev buttons

I'm using the DatePicker widget in conjunction with some next/prev buttons for switching the dates. I'm also setting a two-week window around the current date. The next/prev buttons are disabled accordingly when you select a date at either end of the window. The bug is - when future date is selected from the calendar, and then one of the next/prev buttons are used, the date text disappears. And after the first time the bug occurs, it will sometimes happen for previous dates too. Below is a working example of my code. Any help is appreciated!

[Solved] internalization lagging

Hi team,

Seems kendo.messages.fr-FR.js (19 KB) has been abandoned since the dawn of time!! Compared to kendo.messages.en-US.js (39 KB).

Seriously?? Many many translations are missing, at least half.

Could you please update that please?

I wouldn't blame you if you only update that one and not the derivatives.

Best regards,

Laurent.

When object in datasource somethimes is empty in kendo grid

I have a object that looks like this:

"employees":[
  {"lastName":"Doe"},
  {"firstName":"Anna" },
  {"firstName":"Peter", "lastName":"Jones"}
]

As you can see sometimes one of the properties is missing, sometimes lastname may be missing and other times firstname is missing.

The problem is when I use kendo grid (Jquery UI) because defining the columns I set something similar

$("#grid").kendoGrid({
  columns: [{
    field: "firstName",
    title: "Firstname",
    template: "Firstname: #:firstName#"
  },{
    field: "lastName",
    title: "Lastname" 
    template: "Lastname: #:lastName#"
  }

Because sometime the firsname is NULL and the same with lastName. The problem comes in the template. So how can I handle this?
I am not able to edit the datasource because it comes from a external api.

Here is an exampleof the replicated issue: https://dojo.telerik.com/uPUdiYOC

Code:

  columns: [ {
