Getting a Maximum call stack size exceeded error when trying to read more than 1000 records in Org Chart

Hi there, can you please tell me if this is a bug? or if I'm doing something wrong.

I get this error when I try to read 2000 records in from API, it says "Maximum call stack size exceeded". The response is retrieved but when the results are not showing in the Org Chart. They do show when I read 1000 records.

Kendo Chart Axis Label (categoryAxis)

Hi. I have a single JSON Array like this:

[{
            "country": "Spain",
            "year": "2008",
            "unit": "GWh",
            "solar": 2578,
            "hydro": 26112,
            "wind": 32203,
            "nuclear": 58973
}];

And, What I want to do is make this single array into a chart. (I hope the name of the series is the same as the axis text.)

Like this.

but, If I write code like this... All series are included in one category. How can I solve this?

var tempData = [{
    "country": "Spain",
    "year": "2008",
    "unit": "GWh",
    "solar": 2578,
    "hydro": 26112,
    "wind": 32203,
    "nuclear": 58973
}];

$("#chart").kendoChart({
    dataSource: {
        data : tempData
    },
    series:
    [{
        field: "nuclear",
        name: "Nuclear"
    }, {
        field: "hydro",
        name: "Hydro"
    }, {
        field: "wind",
        name: "Wind"
    }],
    categoryAxis: {
      categories: ["Nuclear", "Hydro", "Wind"]
    }
});

Attributes in kendo template not being replaced correctly for custom tools for Kendo editor jp

Hello,

I am debugging my code using Kendo Dojo example, https://demos.telerik.com/kendo-ui/editor/custom-tools, then click "Edit in Kendo UI Dojo" https://dojo.telerik.com/uyaWeQeb .

Here's the code I added to the example in tools array:

,{
name: "addTagv2",

tooltip: "Add a tag/segment",
label: "tag/segment",
template: '<button style="padding-left: 5px !important;" type="button" name="#: name #" title="#: tooltip #">#: label #</button>'

},
{
name: "editTagv2",

tooltip: "Edit a tag/segment",
label:"tag/segment",
template:'<button style="padding-left: 5px !important;" type="button" name="#: name #" title="#: tooltip #">#: label #</button>'
}

However, when I inspect the buttons I see the following HTML rendered:

<button style="padding-left: 5px !important;" type="button" name="Dojo output" title="Add a tag/segment" tabindex="-1">tag/segment</button>

<button style="padding-left: 5px !important;" type="button" name="Dojo output" title="Edit a tag/segment" tabindex="-1">tag/segment</button>

Where is "Dojo output" coming from? Is "name" a reserved word or property for the tool button.

Thanks,

James

Kendo-grid resize column will reset the grid, reverting to original values. How do I make resized widths stay set?

AngularJS version 1.5.8.
Kendo UI version 2016.3.914+Official

I have a kendo grid with the resizeable property set to true. However, when I display the grid and then use my cursor to resize the grid, it appears the grid rebinds the data and reverts all columns to their original size.

How do I make resized widths stay set?
Are there any properties I should look at to help with this issue?

Kendo UI - Drag and Drop functionality not working as expected within a Scheduler component

Context

We're using Scheduler component and a custom list of items. We're also using the Draggable component to let the items to be dropped into the Scheduler component. You can find the layout of the implementation in the attachment.

The configuration of the items is the following:

$(element)
  .find(`.${NS}customer-list__draggable`)
  .kendoDraggable({
    hint: () => {
      var draggableElem = $(`
      <span class="ui-draggable ${NS}customer-list__dragging">
        ${scope.customer.name} <br>
      </span>
      `);
      draggableElem.css({
        borderLeft: `3px solid ${scope.customer.displayColor}`
      });
      return draggableElem;
    },
    dragstart: event => {
      // prevent dragging on agenda view
      if ($rootScope.scheduler.viewName() === "agenda") {
        event.preventDefault();
      }
    },
    autoScroll: false,
    containment: "window",
    cursorOffset: { right: 0, top: 0, left: 0, bottom: 0 },
    distance: 50,
    group: "schedulerCustomerGroup"
  });

The configuration of the Drop are is the following:

scheduler.view().table.kendoDropTargetArea({
  group: 'schedulerCustomerGroup',
  filter: '.k-scheduler-table td, .k-scheduler-header-all-day td, .k-event',
  dragenter: (e) => {
    var offset = $(e.dropTarget).offset(),
          slot = scheduler.slotByPosition(offset.left, offset.top);

    $(slot.element).css('background', '#bce8f1');
  },
  dragleave: (e) => {
    var offset = $(e.dropTarget).offset(),
          slot = scheduler.slotByPosition(offset.left, offset.top);

    $(slot.element).css('background', '');
  },
  drop: (event) => {
    var offset = $(event.dropTarget).offset(),
        slot = scheduler.slotByPosition(offset.left, offset.top),
        dragElem = event.draggable.element[0],
        customer = _.find($rootScope.customers, {id: $(dragElem).data('customerId')});

    $(slot.element).css('background', '');

    scheduler.addEvent({
      title: customer.name,
      start: slot.startDate,
      end: slot.endDate,
      description: '',
      customerId: customer.id,
      streetAddr: customer.streetAddr,
      city: customer.city,
      state: customer.state,
      country: customer.country,
      zip: customer.zip,
      phone: customer.phone,
      lat: customer.lat,
      long: customer.long,
      accountId: customer.accountId,
      contactId: customer.d_tx_uid,
      isAllDay: slot.isDaySlot,
    });
  }
});

You can notice the group setting is the same in both configurations: schedulerCustomerGroup.

The filter configured in the kendoDropTargetArea is the following:

.k-scheduler-table td
.k-scheduler-header-all-day td
.k-event

As you can see, the filter include all the cells in the Scheduler component.

Problem

The problem I'm having is when using the Work Week, and resizing the browser to an specific dimension, some cells are not being detected as drop area.

As you can see, I cannot drop the item in Wed 2/21.

A workaround is to resize the browser, but that's not a final solution I'm expecting to have.

Kendo UI - can I drag across the range slider by dragging the tooltip?

I'm using the range slider from Kendo UI for jQuery. It provides a drag handle and a tooltip that is not draggable. Is it possible to make it so that I can click and drag the tooltip to move the drag handle across the slider? The file for this is fairly dense and I am not the original author so I'm not sure what to provide for reference. I'm just wondering if it's possible even thought it's not covered in the Kendo docs as far as I can tell.

Insert Image tool does not insert image at current position.

Hii,

I am using Kendo version Kendo UI v2020.2.617 in our project, and while using insertImage tool from the editor I am facing some issues.

Following are the issues I faced -

1. When I select the insertImage tool and try adding an image at a certain position, it jumps to the top of the editor (Once in multiple try it sticks at a certain position).

2. insertImage tool does not render images from all URLs. I entered multiple URLs but only on some URLs I got an image rendered.
