We need your feedback, because we are considering changes in the release approach for Kendo UI for jQuery. Please provide your feedback in the comments section below:


1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?

2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?

3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

I have a sample at https://js.do/sun21170/kendouitextboxsample1, which shows up as in the screenshot below when rendered.

When I run the same sample at https://dojo.telerik.com/QASrBLOT, this problem is not there because no autofill occurs.

So, my question is how to prevent the overlap in my first sample when the autofill is occurring?

When I use the DatePicker, the calendar displays a date between the minimum and maximum values, which is fine. However, if I manually enter a date before the minimum or after the maximum value, nothing prevents me from doing so. Even worse, the change event is no longer triggered. There's no way to validate the input manually if it's out of range.

Wouldn't it have been better for the control to block manually entered values ​​that exceed the allowed range?

I'd like to build a grid of divs.
I have an array of arrays, like this:

[ [ { "value": "0"}, { "value": "1", } ] ]

(Sorry, but I can't indent the code properly in the editor.)

I can't do it with MVVM.

This is how I do it:

Template container:

<div data-bind="source: matrix" data-template="frame-cells-row-tmpl">
</div>


Template row:

<script type="text/x-kendo-template" id="frame-cells-row-tmpl">
<div class="frame-grid-row" data-bind="source: data" data-template="frame-cells-col-tmpl">
</div>
</script>


Template col:

<script type="text/x-kendo-template" id="frame-cells-col-tmpl">
    <div class="frame-grid-col">
         #: value #
    </div>
</script>


The error I get is:

Uncaught TypeError: e.bind is not a function

 


It works fine if I do this:

<script type="text/x-kendo-template" id="frame-cells-row-tmpl">
    <div class="frame-grid-row" >

 ## for(var i=0; i < data.length; i++) { ##
<div class="frame-grid-cell">
 ##= data[i].value ##
            </div>
 ## } ##

    </div>
</script>

Why can't I use MVVM?

In the "row" template, is "data" the correct variable name for "source"?

Many thanks!

I have a need for a slider switch with text labels instead of numbers. Instead of 1,2,3 I need Small, Medium, Large. It does not appear that Kendo UI has a built in way to do this so here is the function I came up with: 

/*
    This helper is designed to allow you to substitute a datasource for values in a kendo slider to do things like:
    "small", "medium", "large". 
    
    It includes 4 functions that should be used instead of the ones included with Kendo UI:

    initializeKendoSlider(options);
    getKendoSliderSelection(elementId);
    resizeKendoSlider(elementId);
    setKendoSliderValue(elementId, newValue);
*/

function initializeKendoSlider(options) {
    /*
        options = {
            elementId: string - required,
            dataSource: [{ label: string, value: any}],
            value: any - the value prop of any dataSource item
            orientation: string - defaults to "horizontal",
            tickPlacement: string - defaults to "bottomRight",
            change: custom change function. Available parameters are: selectedDataItem, e
        };

        Include this in your html to start: 
        <input id="mySlider" name="mySlider" type="text" />

        NOTE: If a proper dataSource is not passed, the slider will build as a numeric Kendo Slider.
        NOTE: The value returned by the .value() function is the index, not the actual value. You must use
              the included getKendoSliderSelection and setKendoSliderValue functions.
        NOTE: The change function will return the selected item as the second parameter which can be used in your custom change function.
        NOTE: Kendo's built in max and min methods will not work properly when using a dataSource.
        NOTE: Small steps are not supported.
    */

Hello. I am planning to use the taskboard for my code, but I would like to customize it a little bit. However Im finding almost any customization to be not possible. Im working with Copilot and its telling me a couple things that dont appear to be true:

1. On the datasource tab, I have commented out code because Copilot has told me that if I use the from attribute when defining the model that those fields would automatically map to its default title and description fields. It stays undefined until I switch to the default values.

2. The custom editor I have specified does not get acknowledged by the code. It simply loads the default one with Title and description fields. At the very minimum I just want it to show different labels than title and descritpion, such as PartyName and comments. However Im not seeing any way to not just load the out of the box solution. 

Are my requests possible? The example code on this site just appear to use out of the box editing and mapping.


<body>
    <div id="taskBoard"></div>
    <script id="JurisdictionEditor" type="text/x-kendo-template">
        <div style="padding:2em; color:red;">Custom Editor Rendered!</div>
    </script>
    <script>
        $(function () {
            $("#taskBoard").kendoTaskBoard({
                dataSource: [
                    { id: 1, title: "Jane", description: "Test", status: "cited" }
                    // { id: 1, PartyName: "Jane", comments: "Test", status: "cited" } //doesnt work
                ],
                schema: {
                    model: {
                        id: "id",
                        fields: {
                            id: { type: "number" },
                            title: { from: "PartyName", type: "string" },
                            description: { from: "comments", type: "string" },
                            PartyName: { type: "string" },
                            comments: { type: "string" },
                            status: { type: "string" }
                        }
                    }

I have an editor configured for a column which can reflect multiple values - the multiselect control binds to the source datasource just fine when a grid row is edited or a new record is being created but for the pure edit portion I need to preselect the current values from the grid row datasource - the values are there in the row object because I can see them when I do a console.log of the model field via e.model.get("UserRoleSectors") (example of value is  ["2","25"] ) - however in the grid edit event handler if I try to set the value for the multi-select to ensure it reflects what values are already bound to the record via the statement e.container.find('[name="UserRoleSectors"]').data("kendoMultiSelect").value(e.model.get("UserRoleSectors")); - nothing is selected even though the values are available in the multiselect.  Am I doing something wrong?

editor: function (container, options) {
                  // create an input element
                  var input = $('<select multiple="multiple" />');
                  // set its name to the field to which the column is bound
                  input.attr("name", options.field);
                  // append it to the container
                  input.appendTo(container);
                  // initialize a Kendo UI MultiSelect
                  input.kendoMultiSelect({
                      autoBind: true,
                      valuePrimitive: true,
                      dataTextField: "SectorAcronym",
                      dataValueField: "SectorNo",
                      dataSource: $scope.sectorsDataSource
                  });

Hi Telerik team!

I'm trying to scale my linechart by setting zoom Css property, but this is affecting mouse events and messing up the tooltip position and the marking wrong focused item.

As you can see here:

https://dojo.telerik.com/RQNGZUUK

So, is possible to scale linechart without affect mouse events?

Regards,

Gustavo
