I am seeing an issue with the Kendo Responsive Panel component. There is a Kendo Menu inside the responsive panel, but when displaying the horizontal menu its showing horizontal and vertical scroll bars when hovering over the menu item that says Foo, and also its not showing the menu group item since the height of the responsive panel is limited to the initial height of the horiontal menu. I am using Kendo UI jQuery R2 2020. The code I have is as given below. The dojo sample can be seen at https://dojo.telerik.com/@sun21170/uPisoRoW

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.

Kendo for jQuery and WordPress

I am trying my first steps using jQuery and Kendo in WordPress.

It would be really helpful to get some advice on the following:

I do I install Kendo UI in a WordPress site?
I do I install Kendo UI just in a plugin?

Thanks!

[Solved] Kendo UI JQuery ListView Virtualization

I am trying to virtualize a Kendo UI JQuery list view with local data.

I also made my own Dojo here but it doesn't work. The problem with mine is that it is still creating all of the items, not just the first 5. Any idea how to fix this?

TreeView Expansion When Switching Views in Kendo UI FileManager

Description: We have encountered an issue with the Kendo UI FileManager component related to drag-and-drop uploads and the navigation bar.

Issue Details:

Duplicate Uploads on Drag-and-Drop: When performing a drag-and-drop upload, the file(s) are uploaded twice. This occurs because the API is called twice during the drag-and-drop operation, resulting in duplicate uploads.
Navigation Path Issue: The navigation bar at the top does not function as expected. When clicking a navigation path link, the FileManager navigates back to the home directory instead of the intended path. However, the navigation tree on the left works correctly.

Steps to Reproduce:

Open the Kendo UI FileManager.
Drag and drop a file into the FileManager interface.
Observe the file being uploaded twice.
Click on any path link in the navigation bar at the top.
Observe that it navigates to the home directory instead of the intended path.

Expected Behavior:

The file(s) should be uploaded only once during drag-and-drop.
The navigation bar should correctly navigate to the intended path, similar to the navigation tree on the left.

Attached Video: A video demonstrating both issues have been attached for reference. It shows how the file is uploaded twice during drag-and-drop and how the navigation bar fails to navigate properly.

Attached Source Code: I have also attached my JavaScript and controller upload source code for reference. This will provide additional context for the implementation and may help in identifying the root cause of the issues.

Update multiple rows

I have a grid where user input causes multiple rows to be updated through a complex formula. Currently, I'm using dataItem.set("column", value) to do the update. Unfortunately, this is taking about 20 seconds to complete. Is there a way to speed this up but also not lose the current grid view. For example, If the user scrolled down to record 50, it needs to stay there after the update. No rows are being added or deleted, just the values are changing.

How to keep header configuration when updating Grid options ?

Hello,

I have a kendo grid created from an HTML table like this:

<div class="content">
    <table id='k-grid'>
        <thead>
            <tr>
                <th data-field="my_value1">Title 1</th>
                <th data-field="my_value2">Title 2</th>
            </tr>
        </thead>
    </table>
</div>

I need to update its toolbar at runtime with setOptions in another file and I can't modify the grid setup.
So I did :

const options = kendoGrid.getOptions();
if (!options.toolbar) {
    options.toolbar = [];
}
options.toolbar.push(
    { template: `<div class='vr'></div>` },
    { template: `<select id='my-selector'></select>` }
);
kendoGrid.setOptions({ toolbar: options.toolbar });

But when I refresh the Grid using setOptions, the columns titles are lost and take the value of the data-field attributes.
I know this is expected behavior with reference to the setOptions documentation and the init from Table - documentation.

My goal is to make updating the toolbar completely transparent to creating the grid in order to reuse it on any table without breaking it.

How can I keep the data in the original HTML table and apply it to the newly created grid with setOptions please?
