CheckBoxFor causing JavaScript error and not working

Hello I have the following MVC code in a .cshtml file for an ASP.MVC application:

@(Html.Kendo().CheckBoxFor(m => m.IsNotificationSuppressed).Checked(false).Label("some text"))

Until a few days ago, this line worked fine. But we've recently updated Kendo to the most recent version and now it's throwing the following JavaScript error:

Uncaught TypeError: jQuery(...).kendoCheckBox is not a function

And the checkbox appears but without a label.

I've already determined that neither "m" (the view model) nor the property IsNotificationSuppressed are null. I cannot find any information as to what is causing this CheckBoxFor to not function and its use here matches the examples given in every example I can find for the Kendo checkbox.

What is wrong here and how do I fix this?

Also the kendo.all.min.js file appears to be a 2016 version and ctrl-f for kendocheckbox finds nothing. Is this the problem? How do I update this file and why didn't it update when the rest of Kendo was updated?

Grid checkbox problem

Hello,

I have a question. After updating Kendo UI from version 2017.2.621 to 2017.3.1018, a problem occurred. The checkbox functionality in the grid, which previously had no issues, is no longer working. When I click the checkbox, nothing happens.

If you know how to solve this issue, please help me.

{    title: "사용여부", 
     width: "70px", 
     template: '<input type="checkbox" class="chk k-checkbox" name="useYn" #= useYn =="Y" ? "checked=checked" : "" # />'+
               '<label class="k-checkbox-label"></label>', 
     attributes: { style: "text-align: center" } 
}

CSS Issues After Upgrading to Version 2024.4.1112

Hello

I am currently using a purchased Kendo UI license. I plan to replace my existing Kendo UI with the latest jQuery version 2024.4.1112. Before making the change, I do not know the version I was previously using.

When I check the CSS file, I see the following comment:

/**
* Kendo UI v2017.2.621 (http://www.telerik.com/kendo-ui)
* Copyright 2017 Telerik AD. All rights reserved.
*
* Kendo UI commercial licenses may be obtained at
* http://www.telerik.com/purchase/license-agreement/kendo-ui-complete
* If you do not own a commercial license, this file shall be governed by the trial license terms.
*/

Since someone else developed this project, I am not sure which version was used, and if I try to update to the latest version, there are issues with the CSS.

Currently, my license allows me to download the following versions:
2015.2.624
2022.2.510
2022.2.621
2022.2.802
2022.3.913
2022.3.1109
2023.1.117
2023.1.314
2023.1.425
2024.2.514
2024.3.806
2024.3.1015
2024.4.1112

If I need to upgrade step by step to use the latest version, I am unsure what to do since I cannot find version 2017.2.621. Can you help me figure out how to use the newest version?

Form validation always treats checkbox as required field

I have a form on which there is checkbox control. For some reason the kendo validator always considers the checkbox a required field and considers a non-checked state as invalid. How can I get the validator to ignore the checkbox? As you can see, the field, IsTerminated is not marked required.

<form id="frmEmployee" method="post">
    <div class="control-grid">
        <div class="col-1-label">
            @Html.LabelFor(m => m.Id, "Employee Id: ")
        </div>
        <div class="col-1-control">
            @Html.Kendo().TextBoxFor(m => m.Id).HtmlAttributes(new { @readonly = "", @required = "", @validationMessage = "Id is required" })
        </div>

        <div class="col-2-label">
            @Html.LabelFor(m => m.FirstName, "First Name: ")
        </div>
        <div class="col-2-control">
            @Html.Kendo().TextBoxFor(m => m.FirstName).HtmlAttributes(new { @required = "", @validationMessage = "First Name is required" })
        </div>

        <div class="col-3-label">
            @Html.LabelFor(m => m.LastName, "Last Name: ")
        </div>
        <div class="col-3-control">
            @Html.Kendo().TextBoxFor(m => m.LastName).HtmlAttributes(new { @required = "", @validationMessage = "Last Name is required" })
        </div>

        <div class="col-1-label">
            @Html.LabelFor(m => m.MiddleName, "Middle Name: ")
        </div>
        <div class="col-1-control">
            @Html.Kendo().TextBoxFor(m => m.MiddleName)
        </div>

        <div class="col-2-label">
            @Html.LabelFor(m => m.PreferredName, "Preferred Name: ")
        </div>
        <div class="col-2-control">
            @Html.Kendo().TextBoxFor(m => m.PreferredName)
        </div>

        <div class="col-3-label">
            @Html.LabelFor(m => m.Email, "Email: ")
        </div>
        <div class="col-3-control">
            @Html.Kendo().TextBoxFor(m => m.Email).HtmlAttributes(new { @required = "", @validationMessage = "Email is required" })
        </div>

        <div class="col-1-label">
            @Html.LabelFor(m => m.HireDate, "Hire Date: ")
        </div>
        <div class="col-1-control">
            @Html.Kendo().DatePickerFor(m => m.HireDate).HtmlAttributes(new { @required = "", @validationMessage = "Hire Date is required" })
        </div>

        <div class="col-2-label">
            @Html.LabelFor(m => m.IsTerminated, "Terminated: ")
        </div>
        <div class="col-2-control">
            @Html.Kendo().CheckBoxFor(m => m.IsTerminated)
        </div>

        <div class="col-3-label">
            @Html.LabelFor(m => m.TerminationDate, "Termination Date: ")
        </div>
        <div class="col-3-control">
            @Html.Kendo().DatePickerFor(m => m.TerminationDate)
        </div>

        <div style="display: none;">
            @Html.Kendo().DatePickerFor(m => m.CreatedDate)
        </div>
    </div>
</form>

On page load I have:

    $(document).ready(function ()
    {
        $("#frmEmployee").kendoValidator();
    });

And before I submit my data to the server I have a check:

let validator = $('#frmEmployee').kendoValidator().data('kendoValidator');

if (validator.validate())
{
   // ...
}

validator.validate() always returns false if IsTerminated is not checked. IsTerminated is a non-nullable bool.

A short way of applying a theme to the entire page

If I include a certain kedo ui theme like default or nova or uniform in my asp.net mvc view/web page that uses kendo ui, then what would be the quickest way to apply the kendo ui theme to everything on the asp.net mvc view i.e. to the textboxes, buttons etc.?

The asp.net mvc view/web page is always applying boostrap theme to the textboxes, buttons etc, but I want to change it so that the kendo ui theme gets automatically applied to these textboxes, buttons etc.

I know that I could execute jquery code on document ready event that looks for all elements in the web page and then changes each element to a corresponding kendo ui element (example code as below), but this would involve quite a bit of coding in jquery.

 $(document).ready(function () {
        let allElements = document.querySelectorAll("button,input,textarea");
        console.log("allElements length is " + allElements.length);
        for (let i=0; i < allElements.length; i++) {
            let emt  = allElements[i];
            emt.className = "";
            console.log("element tag name is " + emt.tagName);
             if (emt.tagName === "BUTTON") {
                 $(emt).kendoButton();
            } else if (emt.tagName === "INPUT" && (emt.getAttribute("type") === "text" || emt.getAttribute("type") === "password")) {
                 $(emt).kendoTextBox();
            } else  if (emt.tagName === "TEXTAREA" ) {
                 $(emt).kendoTextArea();
             }
        }
        $(".jumbotron").kendoResponsivePanel({breakpoint:769});
        });

It would be really cool if by simply removing bootstrap.css from the web page, the entire page would automatically have the kendo ui theme applied or a single method could be called on the global kendo ui object like kendo.applyTheme(<theme-name>).

checkbox column in grid

i have a grid with one checkbox column bound to a dataitem. what i just want to do is when you click the checkbox to check/uncheck, it will update the data item.

i've tried copying the sample provided here: https://dojo.telerik.com/ozoHUwUP/5 but the onchange event is not triggered

columns.Bound(p => p.IsApproved).ClientTemplate("<input type='checkbox' class='chkbx k-checkbox' onclick='check()' #= IsApproved ? checked='checked' :'' # #=dirtyField(data,'IsApproved')#/>")

.Title("Approved?").Width(150);

Issue with Label Rendering in KendoUI TreeView Component

We are currently experiencing a rendering issue with the KendoUI TreeView component, version 2019.2.703, on Project Server Online. This problem arose following a recent update to Project Online, which introduced a change in how the WebComponentsIcons font, used for icon rendering, is managed in the cloud environment.

Issue Details:

Previously, the grid component functioned correctly. However, after the update, labels in combo boxes that contain hierarchical items (years and months in our case) are not displaying correctly. Specifically, the label for the year is now rendering "behind" he checkbox and is only partially visible within the interface.

See attachment: TreeView_err1.png

Attempted Fixes and Complications:

We attempted a solution that successfully made the year label visible again modifying the style of the class .k-treeview .k-in (setting the Font Family and size).

.k-treeview .k-in {
border-radius: 0;
margin: 0;
padding: 4px 8px;
border: 0 solid transparent;
text-decoration: none;
display: inline-flex;
align-items: center;
align-content: center;
vertical-align: middle;
position: relative;
font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
font-size: 14px;
}

However, this adjustment led to an unintended change in the Document Object Model, and an empty <span> cover the checkbox and partially blocked the selection of the checkbox.

See attachment: TreeView_err2.png

To avoid the conflict between the checkbox and the empty span we modified the style of the .k-icon class changing the display from inline-block to display: contents;

Now, the trigger, originally on the triangle icon for showing/hiding child items (months), is incorrectly positioned above the checkbox for selecting the year. This results in all child items being expanded and displayed when the parent is selected, which is not the desired behaviour.

See attachment: TreeView_err3.png

Attachments:

Please find attached screenshots for a better understanding of the issues described.

Request:

Could you please investigate this behaviour? Any suggestions on how to correct the year label rendering without affecting the functionality of the child item display would be greatly appreciated.

I want to know how to limit the number of checkboxes per row in the CheckBoxGroup function.

(Before getting into the article, I apologize for my poor English skills.)

Hello! you guys always help me.

I need to create checkboxes using kendoCheckBoxGroup function in specific fields of KendoForm.

However, it should be limited to 4 per line, not listed in one line.

Expressing it pictorially is as follows:

(Note, the text that goes into the field will vary in length.)

And, the code I'm working on is below.

var items = [
        {value: "item1", label: "Item 1"},
        {value: "item2", label: "Item 2"},
        {value: "item3", label: "Item 3"},
        ...
        {value: "item14", label: "Item 14"},
    ];

$('#checkBoxField').kendoCheckBoxGroup({
    items: items,
    layout: "horizontal"
});
