Kendo Stacked Bar : Using stackValue for totals doesn't display correct amount if value is negative

I have a stacked kendo bar chart defined as follows:

$("#chart").kendoChart({
                title: {
                    text: ""
                },
                legend: {
                    visible: false
                },
                seriesDefaults: {
                    type: "bar",
                    stack: true
                },
                series: [{
                    name: "Value1",
                    data: [-40, 32, 34, 36, 45, 33, -34, 83, 36, 37, 44, 37, 35, 36, 46],
                    color: "#f3ac32"
                }, {
                    name: "Value2",
                    data: [19, 25, -21, 26, 28, 31, 35, 60, 31, 34, 32, 24, 40, 38, 29],
                    color: "#b8b8b8"
                }, {
                    name: "Value3",
                    data: [17, 17, 16, -28, 34, 30, 25, 30, -27, -37, 25, 33, 26, 36, 29],
                    color: "#bb6e36",
                  	labels: {
                			template: "#= stackValue #",
                			visible: true
                		},
                }],
                valueAxis: {
                    max: 180,
                    line: {
                        visible: false
                    },
                    minorGridLines: {
                        visible: true
                    }
                },
                categoryAxis: {
                    categories: [1952, 1956, 1960, 1964, 1968, 1972, 1976, 1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012],
                    majorGridLines: {
                        visible: false
                    }
                },
                tooltip: {
                    visible: true,
                    template: "#= series.name #: #= value #"
                }
            });

But the sum displayed at the end of the bar is not correct in the cases where data is negative.

See the output below :

How do I get it to display the correct sum?

How to display treeMap value on the chart along with the name?

I want to be able to display the treemap value on the TreeMap chart.

My TreeMap Definition :

$("#treeMap").kendoTreeMap({
    dataSource: {
        data: [{
            items: [{
                name: "Seg1",
                value: 54
            },
            {
                 name: "Seg2",
                 value: 37
            },
            {

Is there a way to declare a databound function for kendo grid inside an another grid?

I want to resize my grid that inside another grid. These grids are hierarchical. I wrote something for that but this works for second click. The processes I mentioned are seen in the pictures (firstclick, secondclick). the red circle shows extand button.

The js code block I wrote for solution but it does not work properly:

// The code inside the databound function of master grid
    $("#SiparisListeleGrid td a.k-icon").click(function () { // onclick for a element that opens second grid inside the row
        if ($(this).hasClass("k-i-expand")) { // if the grid is expand

            // uid of tr element
            var tr_UID = $(this).parents("tr").data("uid");

            // master grid
            var ustGrid = $("#SiparisListeleGrid").data("kendoGrid");

            $(ustGrid.dataSource.data()).each(function (i, item) {
                if (item.uid == tr_UID) {
                    var altGrid = $("#Grid_SiparisSatir_" + item.SipUstID).data("kendoGrid");
                    var rowCount = altGrid.dataSource.view().length;

                    $("#Grid_SiparisSatir_" + item.SipUstID).attr("style", "height:" + (rowCount * 40 + 125) + "px;");

                    $("#Grid_SiparisSatir_" + item.SipUstID + " .k-grid-content").css("height", (rowCount * 40));

                    $("#Grid_SiparisSatir_" + item.SipUstID + " .k-grid-content-locked").css("height", (rowCount * 40));
                }
            });
        }
    });
    // This code block only works on second clicking the expan button.
    // Does not recognize the second grid when clicked for the firs time
    // Should I use databound for second grid? However I do not know how can I do that.

custom theme not transferred

Hello all,

I have the problem that my custom theme is not transferred to my application.

As code I copied the code from the tile layout example (https://demos.telerik.com/kendo-ui/tilelayout/index?_ga=2.175878118.554134959.1665135807-2026844688.1664867263&_gl=1*1inatwj*_ga*MjAyNjg0NDY4OC4xNjY0ODY3MjYz*_ga_9JSNBCSF54*MTY2NTE0Mjk5MS4yLjEuMTY2NTE0NDE5MS4wLjAuMA..) and adapted the linked script-sources to my paths.

After the script-sources i linked the css of my theme: (image0)

my theme has the following color scheme: (image1)

But now when I launch my application, the TileLayout looks like this: (image2)

When I use F12 to display the properties, for example of the donut chart, I see the following: (image3)

i do not understand, where the fill="#ff6800" comes from, since it is not even displayed in the style window of the F12 menu.

I can't get the problem solved, can anyone help me?

Template inside a template

I am using the Scheduler and making a custom edit screen. I am following the example here.

Each scheduled event can have a category. These are selectable via dropdown. Consider the following portion of the template:

<div class="k-edit-label">
   <label for="category">Category</label>
</div>
<div data-container-for="category" class="k-edit-field">
   <!-- HERE IS WHERE THE DROPDOWN IS -->
</div>

In the example linked, a simple <select> element is used. But I am looking to add a real Kendo dropdown, not a basic select. So I defined it as follows:

var categoryEditorDropdown = Html.Kendo().DropDownList()
   .AutoBind(true)
   .BindTo(categories)
   .DataTextField(nameof(Category.Description))
   .DataValueField(nameof(Category.Id))
   .HeaderTemplate("Custom defined template which is why I need this over a select")
   .OptionLabelTemplate("Custom defined template which is why I need this over a select")
   .Name("category")
   .ToClientTemplate();

Back to my editor template, for the commented green line I tried both the following, and both gave template errors:

<div data-container-for="category" class="k-edit-field">
   <!-- Both fail with a template error -->
   @categoryEditorDropdown
   @Html.Raw(categoryEditorDropdown)
</div>

Next, I made a separate script:

<script id="editEventCategoryTemplate" type="text/x-kendo-template">
   // Tried both of these and again both fail when editing the event
   @categoryEditorDropdown
   @Html.Raw(categoryEditorDropdown)
</script>

And I updated the editor to try and use it:

<div data-container-for="category" class="k-edit-field">
   #= kendo.render(kendo.template($("\\#editEventCategoryTemplate").html())) #
</div>

For both tests here the page renders but then throws the same invalid template error when I try to edit an event.

How can I embed templates into each other. I need far more than category here. There are 6 templates in total needed for 6 different fields.

Datepicker loses readonly status on kendo.bind

It seems that if you set a data-format (or other options like data-min, data-max) on a datepicker and call kendo.bind then the readonly status is lost. Is this the expected behavior, as it doesn't seem correct?

See example:

Move html with dropdownlist from one div to another after initialization

I have a block of html that I want to move from one div to another div on the page using javascript. I am writing a function that will move this code block and will have no idea if, or how many, dropdown lists exist as it will be different every time. My problem is that when I do a .clone(true, true) with JQuery, the dropdownlist either stops opening or it opens with a width of 0 in the upper left corner of the screen. How do I fix this?

Task: Move everything from block1 to block2.

<div id="block1">
<p>Hi! I'm a paragraph.</p>
<select id="select1"></select>
The select was already initialized with JS and works fine.
</div>

<div id="block2">

</div>
